12af39cad7 ARM: OMAP2+: hwmod: disable ick autoidling when a hwmod requires that
Deny autoidle for hwmods with the OCPIF_SWSUP_IDLE flag,
that makes hwmods working properly which cannot handle
autoidle properly in lower power states.
Affected is e. g. the omap_hdq.
Since an ick might have mulitple users, autoidle is disabled
when an individual user requires that rather than in
_setup_iclk_autoidle. dss_ick is an example for that.

2ed5c2e3f2 SoC fixes for omaps for v5.0-rc cycle
This series contains two SoC regression fixes and one uninitialized
 variable fix:
 
 - Fix inverted nirq pin handling for omap5 that started producing
   warnings with earlier GIC direction checks and took a while to
   understand and confirm. Basically there are two sys_nirq pins
   that are bypassing peripheral modules and inverted automatically
   by the SoC and need to be handled with a custom irq_set_type()
 
 - Recent ti-sysc changes caused a regression to the pwm-omap-dmtimer
   code where the device tree handling code for timer source clock
   gets confused. It looks like we can remove that code eventually,
   but for now we just drop a bogus pm_runtime_irq_safe() for the
   timers with the related quirks caused by pm_runtime_irq_safe(),
   and have the standard assigned-clocks and assigned-clock-parents
   deal with setting the source clock
 
 - Fix potentially uninitialized value for display init code if
   regmap_read() fails

So don't bother making it a user visible options that is selected

da4f07ddc1 ARM: dts: qcom-apq8060: Fix up interrupt parents
Before we fixed up the interrupt hierarchy for the SSBI
GPIO controller, we had to use the PM8058 directly to pick
interrupts. After making the interrupt controller work properly,
we can reference the real interrupt parent.

582648f5ef arm: dts: qcom: mdm9615: add interrupt controller properties
Add interrupt controller properties now that ssbi-gpio is a proper
hierarchical IRQ chip. The interrupts property is no longer needed so
remove it.

Note that the IRQs started at 24 instead of 192 like all of the other
PMICs. This is the same IRQs as the MPP for this board. qcom-pm8xxx.c
doesn't set the shared IRQs so this is highly likely to be a copy and
paste error.

fc67e6f120 ARM: 8835/1: dma-mapping: Clear DMA ops on teardown
Installing the appropriate non-IOMMU DMA ops in arm_iommu_detch_device()
serves the case where IOMMU-aware drivers choose to control their own
mapping but still make DMA API calls, however it also affects the case
when the arch code itself tears down the mapping upon driver unbinding,
where the ops now get left in place and can inhibit arch_setup_dma_ops()
on subsequent re-probe attempts.

Fix the latter case by making sure that arch_teardown_dma_ops() cleans
up whenever the ops were automatically installed by its counterpart.

de9c0d49d8 ARM: 8833/1: Ensure that NEON code always compiles with Clang
While building arm32 allyesconfig, I ran into the following errors:

  arch/arm/lib/xor-neon.c:17:2: error: You should compile this file with
  '-mfloat-abi=softfp -mfpu=neon'

  In file included from lib/raid6/neon1.c:27:
  /home/nathan/cbl/prebuilt/lib/clang/8.0.0/include/arm_neon.h:28:2:
  error: "NEON support not enabled"

Building V=1 showed NEON_FLAGS getting passed along to Clang but
__ARM_NEON__ was not getting defined. Ultimately, it boils down to Clang
only defining __ARM_NEON__ when targeting armv7, rather than armv6k,
which is the '-march' value for allyesconfig.

>From lib/Basic/Targets/ARM.cpp in the Clang source:

  // This only gets set when Neon instructions are actually available, unlike
  // the VFP define, hence the soft float and arch check. This is subtly
  // different from gcc, we follow the intent which was that it should be set
  // when Neon instructions are actually available.
  if ((FPU & NeonFPU) && !SoftFloat && ArchVersion >= 7) {
    Builder.defineMacro("__ARM_NEON", "1");
    Builder.defineMacro("__ARM_NEON__");
    // current AArch32 NEON implementations do not support double-precision
    // floating-point even when it is present in VFP.
    Builder.defineMacro("__ARM_NEON_FP",
                        "0x" + Twine::utohexstr(HW_FP & ~HW_FP_DP));
  }

Ard Biesheuvel recommended explicitly adding '-march=armv7-a' at the
beginning of the NEON_FLAGS definitions so that __ARM_NEON__ always gets
definined by Clang. This doesn't functionally change anything because
that code will only run where NEON is supported, which is implicitly
armv7.

The pfla02 SoM has a Micrel KSZ9031RNX ethernet phy connected to the FEC,
which needs RX and TX clock skew settings to compensate for differences
in line length. The skew values are taken from barebox commit
4c65c20f1071 ("ARM: pfla02: Set new ethernet phy tx timings"), which
is based on patches originally provided by Phytec:

    TX_CLK line is approx. 54mm longer than other TX lines which adds
    a delay of 0.36ns. RGMII need a delay of min. 1.0ns. This mean we
    have to add a delay of 0.64ns. We choose 0.78 to have a little gap.
    This can be done by setting GTX pad skew value to 11100
    Also add a delay for the RX delay lines, needed for the Duallite
    variant.  => Set register 2.8 (RGMII Clock Pad Skew) to 0x039F.

29f0023d01 ARM: dts: meson8b: fix the Ethernet data line signals in eth_rgmii_pins
According to the Odroid-C1+ schematics the Ethernet TXD1 signal is
routed to GPIOH_5 and the TXD0 signal is routed to GPIOH_6.
The public S805 datasheet shows that TXD0 can be routed to DIF_2_P and
TXD1 can be routed to DIF_2_N instead.

The pin groups eth_txd0_0 (GPIOH_6) and eth_txd0_1 (DIF_2_P) are both
configured as Ethernet TXD0 and TXD1 data lines in meson8b.dtsi. At the
same time eth_txd1_0 (GPIOH_5) and eth_txd1_1 (DIF_2_N) are configured
as TXD0 and TXD1 data lines as well.
This results in a bad Ethernet receive performance. Presumably this is
due to the eth_txd0 and eth_txd1 signal being routed to the wrong pins.
As a result of that data can only be transmitted on eth_txd2 and
eth_txd3. However, I have no scope to fully confirm this assumption.

The vendor u-boot sources for Odroid-C1 use the following Ethernet
pinmux configuration:
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_6, 0x3f4f);
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_7, 0xf00000);
This translates to the following pin groups in the mainline kernel:
- register 6 bit  0: eth_rxd1 (DIF_0_P)
- register 6 bit  1: eth_rxd0 (DIF_0_N)
- register 6 bit  2: eth_rx_dv (DIF_1_P)
- register 6 bit  3: eth_rx_clk (DIF_1_N)
- register 6 bit  6: eth_tx_en (DIF_3_P)
- register 6 bit  8: eth_ref_clk (DIF_3_N)
- register 6 bit  9: eth_mdc (DIF_4_P)
- register 6 bit 10: eth_mdio_en (DIF_4_N)
- register 6 bit 11: eth_tx_clk (GPIOH_9)
- register 6 bit 12: eth_txd2 (GPIOH_8)
- register 6 bit 13: eth_txd3 (GPIOH_7)
- register 7 bit 20: eth_txd0_0 (GPIOH_6)
- register 7 bit 21: eth_txd1_0 (GPIOH_5)
- register 7 bit 22: eth_rxd3 (DIF_2_P)
- register 7 bit 23: eth_rxd2 (DIF_2_N)

Drop the eth_txd0_1 and eth_txd1_1 groups from eth_rgmii_pins to fix the
Ethernet transmit performance on Odroid-C1. Also add the eth_rxd2 and
eth_rxd3 groups so we don't rely on the bootloader to set them up.

iperf3 statistics before this change:
- transmitting from Odroid-C1: 741 Mbits/sec (0 retries)
- receiving on Odroid-C1: 199 Mbits/sec (1713 retries)

iperf3 statistics after this change:
- transmitting from Odroid-C1: 667 Mbits/sec (0 retries)
- receiving on Odroid-C1: 750 Mbits/sec (0 retries)

d2b91ab148 ARM: dts: imx6*-apalis/-colibri: mark I2C recovery GPIOs as open drain
Since commit d2d0ad2aec ("i2c: imx: use open drain for recovery
GPIO") GPIO lib expects this GPIO to be configured as open drain.
Make sure we define this GPIO as open drain in the device tree.
This gets rid of the following warning:
  gpio-81 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file

Note that currently the i.MX pinctrl driver does not support
enabling open drain directly, so this patch has no effect in
practice. Open drain is enabled by the fixed pinmux entry.

41ea39101d y2038: Add time64 system calls
This series finally gets us to the point of having system calls with
 64-bit time_t on all architectures, after a long time of incremental
 preparation patches.
 
 There was actually one conversion that I missed during the summer,
 i.e. Deepa's timex series, which I now updated based the 5.0-rc1 changes
 and review comments.
 
 The following system calls are now added on all 32-bit architectures
 using the same system call numbers:
 
 403 clock_gettime64
 404 clock_settime64
 405 clock_adjtime64
 406 clock_getres_time64
 407 clock_nanosleep_time64
 408 timer_gettime64
 409 timer_settime64
 410 timerfd_gettime64
 411 timerfd_settime64
 412 utimensat_time64
 413 pselect6_time64
 414 ppoll_time64
 416 io_pgetevents_time64
 417 recvmmsg_time64
 418 mq_timedsend_time64
 419 mq_timedreceiv_time64
 420 semtimedop_time64
 421 rt_sigtimedwait_time64
 422 futex_time64
 423 sched_rr_get_interval_time64
 
 Each one of these corresponds directly to an existing system call
 that includes a 'struct timespec' argument, or a structure containing
 a timespec or (in case of clock_adjtime) timeval. Not included here
 are new versions of getitimer/setitimer and getrusage/waitid, which
 are planned for the future but only needed to make a consistent API
 rather than for correct operation beyond y2038. These four system
 calls are based on 'timeval', and it has not been finally decided
 what the replacement kernel interface will use instead.
 
 So far, I have done a lot of build testing across most architectures,
 which has found a number of bugs. Runtime testing so far included
 testing LTP on 32-bit ARM with the existing system calls, to ensure
 we do not regress for existing binaries, and a test with a 32-bit
 x86 build of LTP against a modified version of the musl C library
 that has been adapted to the new system call interface [3].
 This library can be used for testing on all architectures supported
 by musl-1.1.21, but it is not how the support is getting integrated
 into the official musl release. Official musl support is planned
 but will require more invasive changes to the library.

fd659cc095 arch: System call unification and cleanup
The system call tables have diverged a bit over the years, and a number
 of the recent additions never made it into all architectures, for one
 reason or another.
 
 This is an attempt to clean it up as far as we can without breaking
 compatibility, doing a number of steps:
 
 - Add system calls that have not yet been integrated into all
   architectures but that we definitely want there. This includes
   {,f}statfs64() and get{eg,eu,g,p,u,pp}id() on alpha, which have
   been missing traditionally.
 
 - The s390 compat syscall handling is cleaned up to be more like
   what we do on other architectures, while keeping the 31-bit
   pointer extension. This was merged as a shared branch by the
   s390 maintainers and is included here in order to base the other
   patches on top.
 
 - Add the separate ipc syscalls on all architectures that
   traditionally only had sys_ipc(). This version is done without
   support for IPC_OLD that is we have in sys_ipc. The
   new semtimedop_time64 syscall will only be added here, not
   in sys_ipc
 
 - Add syscall numbers for a couple of syscalls that we probably
   don't need everywhere, in particular pkey_* and rseq,
   for the purpose of symmetry: if it's in asm-generic/unistd.h,
   it makes sense to have it everywhere. I expect that any future
   system calls will get assigned on all platforms together, even
   when they appear to be specific to a single architecture.
 
 - Prepare for having the same system call numbers for any future
   calls. In combination with the generated tables, this hopefully
   makes it easier to add new calls across all architectures
   together.
 
 All of the above are technically separate from the y2038 work,
 but are done as preparation before we add the new 64-bit time_t
 system calls everywhere, providing a common baseline set of system
 calls.
 
 I expect that glibc and other libraries that want to use 64-bit
 time_t will require linux-5.1 kernel headers for building in
 the future, and at a much later point may also require linux-5.1
 or a later version as the minimum kernel at runtime. Having a
 common baseline then allows the removal of many architecture or
 kernel version specific workarounds.

This is a bit larger than normal, as we had not managed to send out

 - tango: one fix for multiplatform configurations broken on other
   platforms when tango is enabled
 - arm_scmi: device unregistration fix
 - iop32x: fix kernel oops from extraneous __init annotation
 - pxa: remove a double kfree
 - fsl qbman: close an interrupt clearing race
 
 The rest is the usual collection of smaller fixes for device tree
 files, on the renesas, allwinner, meson, omap, davinci, qualcomm
 and imx platforms. Some of these are for compile-time warnings,
 most are for board specific functionality that fails to work
 because of incorrect settings.

e7b3ed3380 crypto: arm/crct10dif-ce - cleanup and optimizations
The x86, arm, and arm64 asm implementations of crct10dif are very
difficult to understand partly because many of the comments, labels, and
macros are named incorrectly: the lengths mentioned are usually off by a
factor of two from the actual code.  Many other things are unnecessarily
convoluted as well, e.g. there are many more fold constants than
actually needed and some aren't fully reduced.

This series therefore cleans up all these implementations to be much
more maintainable.  I also made some small optimizations where I saw
opportunities, resulting in slightly better performance.

This patch cleans up the arm version.

(Also moved the constants to .rodata as suggested by Ard Biesheuvel.)

0db5e02230 KVM: arm/arm64: Add kvm_ras.h to collect kvm specific RAS plumbing
To split up APEIs in_nmi() path, the caller needs to always be
in_nmi(). KVM shouldn't have to know about this, pull the RAS plumbing
out into a header file.

Currently guest synchronous external aborts are claimed as RAS
notifications by handle_guest_sea(), which is hidden in the arch codes
mm/fault.c. 32bit gets a dummy declaration in system_misc.h.

There is going to be more of this in the future if/when the kernel
supports the SError-based firmware-first notification mechanism and/or
kernel-first notifications for both synchronous external abort and
SError. Each of these will come with some Kconfig symbols and a
handful of header files.

Create a header file for all this.

This patch gives handle_guest_sea() a 'kvm_' prefix, and moves the
declarations to kvm_ras.h as preparation for a future patch that moves
the ACPI-specific RAS code out of mm/fault.c.

50d6b3cf94 ARM: OMAP2+: fix lack of timer interrupts on CPU1 after hotplug
If we have a kernel configured for periodic timer interrupts, and we
have cpuidle enabled, then we end up with CPU1 losing timer interupts
after a hotplug.

This can manifest itself in RCU stall warnings, or userspace becoming
unresponsive.

The problem is that the kernel initially wants to use the TWD timer
for interrupts, but the TWD loses context when we enter the C3 cpuidle
state.  Nothing reprograms the TWD after idle.

We have solved this in the past by switching to broadcast timer ticks,
and cpuidle44xx switches to that mode at boot time.  However, there is
nothing to switch from periodic mode local timers after a hotplug
operation.

We call tick_broadcast_enter() in omap_enter_idle_coupled(), which one
would expect would take care of the issue, but internally this only
deals with one-shot local timers - tick_broadcast_enable() on the other
hand only deals with periodic local timers.  So, we need to call both.

48166e6ea4 y2038: add 64-bit time_t syscalls to all 32-bit architectures
This adds 21 new system calls on each ABI that has 32-bit time_t
today. All of these have the exact same semantics as their existing
counterparts, and the new ones all have macro names that end in 'time64'
for clarification.

This gets us to the point of being able to safely use a C library
that has 64-bit time_t in user space. There are still a couple of
loose ends to tie up in various areas of the code, but this is the
big one, and should be entirely uncontroversial at this point.

In particular, there are four system calls (getitimer, setitimer,
waitid, and getrusage) that don't have a 64-bit counterpart yet,
but these can all be safely implemented in the C library by wrapping
around the existing system calls because the 32-bit time_t they
pass only counts elapsed time, not time since the epoch. They
will be dealt with later.

d33c577ccc y2038: rename old time and utime syscalls
The time, stime, utime, utimes, and futimesat system calls are only
used on older architectures, and we do not provide y2038 safe variants
of them, as they are replaced by clock_gettime64, clock_settime64,
and utimensat_time64.

However, for consistency it seems better to have the 32-bit architectures
that still use them call the "time32" entry points (leaving the
traditional handlers for the 64-bit architectures), like we do for system
calls that now require two versions.

Note: We used to always define __ARCH_WANT_SYS_TIME and
__ARCH_WANT_SYS_UTIME and only set __ARCH_WANT_COMPAT_SYS_TIME and
__ARCH_WANT_SYS_UTIME32 for compat mode on 64-bit kernels. Now this is
reversed: only 64-bit architectures set __ARCH_WANT_SYS_TIME/UTIME, while
we need __ARCH_WANT_SYS_TIME32/UTIME32 for 32-bit architectures and compat
mode. The resulting asm/unistd.h changes look a bit counterintuitive.

This is only a cleanup patch and it should not change any behavior.

00bf25d693 y2038: use time32 syscall names on 32-bit
This is the big flip, where all 32-bit architectures set COMPAT_32BIT_TIME
and use the _time32 system calls from the former compat layer instead
of the system calls that take __kernel_timespec and similar arguments.

The temporary redirects for __kernel_timespec, __kernel_itimerspec
and __kernel_timex can get removed with this.

It would be easy to split this commit by architecture, but with the new
generated system call tables, it's easy enough to do it all at once,
which makes it a little easier to check that the changes are the same
in each table.

97131f85c0 ARM: dts: qcom: ipq4019: Fix MSI IRQ type
The databook clearly states that the MSI IRQ (msi_ctrl_int) is a level
triggered interrupt.

The msi_ctrl_int will be high for as long as any MSI status bit is set,
thus the IRQ type should be set to IRQ_TYPE_LEVEL_HIGH, causing the
IRQ handler to keep getting called, as long as any MSI status bit is set.

A git grep shows that ipq4019 is the only SoC using snps,dw-pcie that has
configured this IRQ incorrectly.

Not having the correct IRQ type defined will cause us to lose interrupts,
which in turn causes timeouts in the PCIe endpoint drivers.

regulator: fixed/gpio: Pull inversion/OD into gpiolib
This pushes the handling of inversion semantics and open drain

files are also augmented.

This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

We request the "enable" GPIO separately as before, and make sure
that this line is requested as nonexclusive since enable lines can
be shared and the regulator core expects this.

Most users of the GPIO regulator are using device tree.

There are two boards in the kernel using the gpio regulator from a
non-devicetree path: PXA hx4700 and magician. Make sure to switch
these over to use descriptors as well.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before

5388a5b821 ARM: avoid Cortex-A9 livelock on tight dmb loops
machine_crash_nonpanic_core() does this:

	while (1)
		cpu_relax();

because the kernel has crashed, and we have no known safe way to deal
with the CPU.  So, we place the CPU into an infinite loop which we
expect it to never exit - at least not until the system as a whole is
reset by some method.

In the absence of erratum 754327, this code assembles to:

	b	.

In other words, an infinite loop.  When erratum 754327 is enabled,
this becomes:

1:	dmb
	b	1b

It has been observed that on some systems (eg, OMAP4) where, if a
crash is triggered, the system tries to kexec into the panic kernel,
but fails after taking the secondary CPU down - placing it into one
of these loops.  This causes the system to livelock, and the most
noticable effect is the system stops after issuing:

	Loading crashdump kernel...

to the system console.

The tested as working solution I came up with was to add wfe() to
these infinite loops thusly:

	while (1) {
		cpu_relax();
		wfe();
	}

which, without 754327 builds to:

1:	wfe
	b	1b

or with 754327 is enabled:

1:	dmb
	wfe
	b	1b

Adding "wfe" does two things depending on the environment we're running
under:
- where we're running on bare metal, and the processor implements
  "wfe", it stops us spinning endlessly in a loop where we're never
  going to do any useful work.
- if we're running in a VM, it allows the CPU to be given back to the
  hypervisor and rescheduled for other purposes (maybe a different VM)
  rather than wasting CPU cycles inside a crashed VM.

However, in light of erratum 794072, Will Deacon wanted to see 10 nops
as well - which is reasonable to cover the case where we have erratum
754327 enabled _and_ we have a processor that doesn't implement the
wfe hint.

So, we now end up with:

1:      wfe
        b       1b

when erratum 754327 is disabled, or:

1:      dmb
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        wfe
        b       1b

when erratum 754327 is enabled.  We also get the dmb + 10 nop
sequence elsewhere in the kernel, in terminating loops.

This is reasonable - it means we get the workaround for erratum
794072 when erratum 754327 is enabled, but still relinquish the dead
processor - either by placing it in a lower power mode when wfe is
implemented as such or by returning it to the hypervisior, or in the
case where wfe is a no-op, we use the workaround specified in erratum
794072 to avoid the problem.

These as two entirely orthogonal problems - the 10 nops addresses
erratum 794072, and the wfe is an optimisation that makes the system
more efficient when crashed either in terms of power consumption or
by allowing the host/other VMs to make use of the CPU.

I don't see any reason not to use kexec() inside a VM - it has the
potential to provide automated recovery from a failure of the VMs
kernel with the opportunity for saving a crashdump of the failure.
A panic() with a reboot timeout won't do that, and reading the
libvirt documentation, setting on_reboot to "preserve" won't either
(the documentation states "The preserve action for an on_reboot event
is treated as a destroy".)  Surely it has to be a good thing to
avoiding having CPUs spinning inside a VM that is doing no useful
work.

6213f70e7c ARM: smp: remove arch-provided "pen_release"
Consolidating the "pen_release" stuff amongst the various SoC
implementations gives credence to having a CPU holding pen for
secondary CPUs.  However, this is far from the truth.

Many SoC implementations cargo-cult copied various bits of the pen
release implementation from the initial Realview/Versatile Express
implementation without understanding what it was or why it existed.
The reason it existed is because these are _development_ platforms,
and some board firmware is unable to individually control the
startup of secondary CPUs.  Moreover, they do not have a way to
power down or reset secondary CPUs for hot-unplug.  Hence, the
pen_release implementation was designed for ARM Ltd's development
platforms to provide a working implementation, even though it is
very far from what is required.

It was decided a while back to reduce the duplication by consolidating
the "pen_release" variable, but this only made the situation worse -
we have ended up with several implementations that read this variable
but do not write it - again, showing the cargo-cult mentality at work,
lack of proper review of new code, and in some cases a lack of testing.

While it would be preferable to remove pen_release entirely from the
kernel, this is not possible without help from the SoC maintainers,
which seems to be lacking.  However, I want to remove pen_release from
arch code to remove the credence that having it gives.

This patch removes pen_release from the arch code entirely, adding
private per-SoC definitions for it instead, and explicitly stating
that write_pen_release() is cargo-cult copied and should not be
copied any further.  Rename write_pen_release() in a similar fashion
as well.

So, once a CPU has entered cpu_die() it will never, ever leave.

1b5ba35078 ARM: 8824/1: fix a migrating irq bug when hotplug cpu
Arm TC2 fails cpu hotplug stress test.

This issue was tracked down to a missing copy of the new affinity
cpumask for the vexpress-spc interrupt into struct
irq_common_data.affinity when the interrupt is migrated in
migrate_one_irq().

Fix it by replacing the arm specific hotplug cpu migration with the
generic irq code.

This is the counterpart implementation to commit 217d453d47 ("arm64:
fix a migrating irq bug when hotplug cpu").

Tested with cpu hotplug stress test on Arm TC2 (multi_v7_defconfig plus
CONFIG_ARM_BIG_LITTLE_CPUFREQ=y and CONFIG_ARM_VEXPRESS_SPC_CPUFREQ=y).
The vexpress-spc interrupt (irq=22) on this board is affine to CPU0.
Its affinity cpumask now changes correctly e.g. from 0 to 1-4 when
CPU0 is hotplugged out.

72cd4064fc ARM: 8830/1: NOMMU: Toggle only bits in EXC_RETURN we are really care of
ARMv8M introduces support for Security extension to M class, among
other things it affects exception handling, especially, encoding of
EXC_RETURN.

The new bits have been added:

Bit [6]	Secure or Non-secure stack
Bit [5]	Default callee register stacking
Bit [0]	Exception Secure

which conflicts with hard-coded value of EXC_RETURN:

In fact, we only care of few bits:

Bit [3]	 Mode (0 - Handler, 1 - Thread)
Bit [2]	 Stack pointer selection (0 - Main, 1 - Process)

We can toggle only those bits and left other bits as they were on
exception entry.

It is basically, what patch does - saves EXC_RETURN when we do
transition form Thread to Handler mode (it is first svc), so later
saved value is used instead of EXC_RET_THREADMODE_PROCESSSTACK.

071d184a19 ARM: 8826/1: mm: initialize pfn limits with find_limits()
The max_low_pfn value must be set before sparse_init() is called to
keep the early memblock allocations and frees balanced for kmemleak
initialization when sparsemem is enabled.

This commit accomplishes that by replacing the local variables min,
max_low, and max_high with the global limit variables min_low_pfn,
max_low_pfn, and max_pfn respectively in bootmem_init(). The global
variables are initialized directly by find_limits() and used in the
remainder of the function.

This is used when mmapping the PCI resource* files in sys.  Because ARM
currently lacks an implementation of pgprot_device(), it falls back to
pgprot_uncached() (Strongly Ordered), but we should be able to use
Device memory instead.

Doing this speeds up large writes to the resource files by about 40% on
one of my systems.  It also ensures that mmaps on these resources use
the same memory type as ioremap().

1c31d4e96b ARM: 8820/1: mm: Stop printing the virtual memory layout
Since commit ad67b74d24 ("printk: hash addresses printed with

instead of actual addresses:

    Memory: 501296K/524288K available (6144K kernel code, 528K rwdata, 1944K rodata, 1024K init, 7584K bss, 22992K reserved, 0K cma-reserved)
    Virtual kernel memory layout:
	vector  : 0xffff0000 - 0xffff1000   (   4 kB)
	fixmap  : 0xffc00000 - 0xfff00000   (3072 kB)
	vmalloc : 0xe0800000 - 0xff800000   ( 496 MB)
	lowmem  : 0xc0000000 - 0xe0000000   ( 512 MB)
	modules : 0xbf000000 - 0xc0000000   (  16 MB)
	  .text : 0x(ptrval) - 0x(ptrval)   (7136 kB)
	  .init : 0x(ptrval) - 0x(ptrval)   (1024 kB)
	  .data : 0x(ptrval) - 0x(ptrval)   ( 529 kB)
	   .bss : 0x(ptrval) - 0x(ptrval)   (7585 kB)

Instead of changing the printing to "%px", and leaking virtual memory
layout information again, just remove the printing completely, cfr. e.g.
commits 071929dbdd ("arm64: Stop printing the virtual memory
layout") and  31833332f7 ("m68k/mm: Stop printing the virtual
memory layout").

All interesting information (actual section sizes) is already printed by
mem_init_print_info() just above anyway.

9ec5cd0a40 ARM: 8817/1: mm: skip cleaning of idmap page tables on LPAE capable cores
Currently, init_static_idmap() installs some page table entries to
cover the identity mapped part of the kernel image (which is only
about 160 bytes in size in a multi_v7_defconfig Thumb2 build), and
calls flush_cache_louis() to ensure that the updates are visible
to the page table walker on the same core.

When running under virtualization, flush_cache_louis() may take more
than 10 seconds to complete:

[    0.108192] Setting up static identity map for 0x40300000 - 0x403000a0
[   13.078127] rcu: Hierarchical SRCU implementation.

This is due to the fact that set/way ops are not virtualizable, and so
KVM may trap each one, resulting in a substantial delay.

Since only LPAE capable CPUs may execute under virtualization, and
considering that LPAE capable CPUs are guaranteed to have cache
coherent page table walkers (per the architecture), let's only
perform this cache maintenance on non-LPAE cores.

Remove some code that is no longer called now that we make sure never
to invoke the SIMD routine with less that 16 bytes of input.

62fecf295e crypto: arm/crct10dif - revert to C code for short inputs
The SIMD routine ported from x86 used to have a special code path
for inputs < 16 bytes, which got lost somewhere along the way.
Instead, the current glue code aligns the input pointer to permit
the NEON routine to use special versions of the vld1 instructions
that assume 16 byte alignment, but this could result in inputs of
less than 16 bytes to be passed in. This not only fails the new
extended tests that Eric has implemented, it also results in the
code reading past the end of the input, which could potentially
result in crashes when dealing with less than 16 bytes of input
at the end of a page which is followed by an unmapped page.

So update the glue code to only invoke the NEON routine if the
input is at least 16 bytes.

432dd7064a ARM: cns3xxx: Use actual size reads for PCIe
commit 802b7c06ad ("ARM: cns3xxx: Convert PCI to use generic config
accessors") reimplemented cns3xxx_pci_read_config() using
pci_generic_config_read32(), which preserved the property of only doing
32-bit reads.

It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
so it changed writes from always being 32 bits to being the actual size,
which works just fine.

Given that:

- The documentation does not mention that only 32 bit access is allowed.
- Writes are already executed using the actual size
- Extensive testing shows that 8b, 16b and 32b reads work as intended

Allow read access of any size by replacing pci_generic_config_read32()
with the pci_generic_config_read() accessors.

65dbb423cf ARM: cns3xxx: Fix writing to wrong PCI config registers after alignment
Originally, cns3xxx used its own functions for mapping, reading and
writing config registers.

Commit 802b7c06ad ("ARM: cns3xxx: Convert PCI to use generic config
accessors") removed the internal PCI config write function in favor of
the generic one:

  cns3xxx_pci_write_config() --> pci_generic_config_write()

cns3xxx_pci_write_config() expected aligned addresses, being produced by
cns3xxx_pci_map_bus() while the generic one pci_generic_config_write()
actually expects the real address as both the function and hardware are
capable of byte-aligned writes.

This currently leads to pci_generic_config_write() writing to the wrong
registers.

For instance, upon ath9k module loading:

- driver ath9k gets loaded
- The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER,
  located at 0x0D
- cns3xxx_pci_map_bus() aligns the address to 0x0C
- pci_generic_config_write() effectively writes 0xA8 into register 0x0C
  (CACHE_LINE_SIZE)

Fix the bug by removing the alignment in the cns3xxx mapping function.

1531f1b24d ARM: omap2plus_defconfig: remove PROVE_LOCKING from defconfig
PROVE_LOCKING enables LOCKDEP, which causes big overhead on cache and
bus transactions.

On some ARM big.LITTLE architecutres (Exynos 5433) the overhead is really big.
The overhead can be measures using hackbench which will speed up
by x3 times (11sec -> 3.4sec).
When you check transaction on cache or buses, the results are way higher
than normal for the same hackbench test:
L1d cache invalidations: 26mln vs 4mln
L2u cache invalidations: 42mln vs 12mln
bus cyc/access: 30cyc/access vs. 20cyc/access
context switch is x3 times cheaper

Enable this option only when you have some locking issue to investigate.

34332ef736 ARM: multi_v7_defconfig: enable GCC plugin support and structleak plugin
Enable the base GCC plugin support symbol CONFIG_GCC_PLUGINS for
multi_v7_defconfig so that builds hosted on systems that have a
supported version of GCC along with the prerequisite headers will
allow GCC plugins to be used during the build. At the moment, this
will also enable the ARM per-task stack protector plugin, since
all its remaining Kconfig dependencies are fulfilled by default.

At the same time, enable the structleak plugin. This plugin ensures
that local struct type variables are fully initialized, preventing
inadvertent leaks of kernel state if such variables are shared with
userland. This is a reasonable transformation to apply by default,
since it does not adversely affect performance, and does not affect
GCC compiler diagnostics regarding the use of uninitialized local
variables.

abe60a3a7a ARM: dts: Kill off skeleton{64}.dtsi
Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61 ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.

The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

a7403eb27e Allwinner Fixes for 5.0
A couple of device tree fixes for the 5.0 cycle:
 
   - Add missing clock-output-names for the osc24M clock on sun6i/A31
 
     The Linux clock driver uses the device node as the clock name if
     the property is missing. The node name was changed in 5.0-rc1,
     breaking a subtle dependency in the sunxi-ng clock driver, and
     renders Linux unable to completely boot up.
 
   - Add alias for Ethernet controller on Beelink X2
 
     This allows the bootloader to assign a deterministically generated
     MAC address to it.
 
   - Add property to enable USB VBUS regulator on OrangePi Win
 
     The board had defined the constraints for the regulator, but was
     missing the property to actually enable it.

Commit 84badc5ec5 ("ARM: dts: omap4: Move l4 child devices to probe

interconnect target module. Turns out this broke pwm-omap-dmtimer
for reparenting of the timer clock.

With ti-sysc, we can now configure the clock sources in the dts with
assigned-clocks and assigned-clock-parents.

cc0dbf4366 arm: dts: vexpress-v2p-ca15_a7: Add cpu dynamic-power-coefficient information
A CPUfreq driver, like the ARM big.LITTLE driver used on the TC2 board,
which provide the Energy Model with power cost information via the
PM_OPP of_dev_pm_opp_get_cpu_power() function, do need the
dynamic-power-coefficient (C) in the device tree.

Method used to obtain the C value:

C is computed by measuring energy (E) consumption of a frequency domain
(FD) over a 10s runtime (t) sysbench workload running at each Operating
Performance Point (OPP) affine to 1 or 2 CPUs of that FD while the other
CPUs of the system are hotplugged out.

By definition all CPUs of a FD have the the same micro-architecture. An
OPP is characterized by a certain frequency (f) and voltage (V) value.
The corresponding power values (P) are calculated by dividing the delta
of the E values between the runs with 2 and 1 CPUs by t.

With n data tuples (P, f, V), n equal to number of OPPs for this
frequency domain, we can solve C by:

P = Pstat + Pdyn

P = Pstat + CV²f

Cx = (Px - P1)/(Vx²fx - V1²f1) with x = {2, ..., n}

The C value is the arithmetic mean out of {C2, ..., Cn}.

====================
pull-request: bpf-next 2019-01-29

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Teach verifier dead code removal, this also allows for optimizing /
   removing conditional branches around dead code and to shrink the
   resulting image. Code store constrained architectures like nfp would
   have hard time doing this at JIT level, from Jakub.

2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
   code generation for 32-bit sub-registers. Evaluation shows that this
   can result in code reduction of ~5-20% compared to 64 bit-only code
   generation. Also add implementation for most JITs, from Jiong.

3) Add support for __int128 types in BTF which is also needed for
   vmlinux's BTF conversion to work, from Yonghong.

4) Add a new command to bpftool in order to dump a list of BPF-related
   parameters from the system or for a specific network device e.g. in
   terms of available prog/map types or helper functions, from Quentin.

5) Add AF_XDP sock_diag interface for querying sockets from user
   space which provides information about the RX/TX/fill/completion
   rings, umem, memory usage etc, from Björn.

6) Add skb context access for skb_shared_info->gso_segs field, from Eric.

7) Add support for testing flow dissector BPF programs by extending
   existing BPF_PROG_TEST_RUN infrastructure, from Stanislav.

8) Split BPF kselftest's test_verifier into various subgroups of tests
   in order better deal with merge conflicts in this area, from Jakub.

9) Add support for queue/stack manipulations in bpftool, from Stanislav.

10) Document BTF, from Yonghong.

11) Dump supported ELF section names in libbpf on program load
    failure, from Taeung.

12) Silence a false positive compiler warning in verifier's BTF
    handling, from Peter.

13) Fix help string in bpftool's feature probing, from Prashant.

14) Remove duplicate includes in BPF kselftests, from Yue.

ARM: dts: sun5i: q8-tablet: Use bananapi,s070wv20-ct16 panel compatible
The compatible string for the LCD panel used for the Q8 tablets are just
a placeholder that was shown to be compatible with the actual panels
found on these devices. The real panels do not have any identifiable
markings and vary between production runs.

The compatibe string previously used had a pixel clock that could not
be accurately reproduced on Allwinner hardware, and discussions on
whether a margin should be added to the display drivers and how large
a margin was acceptable had stalled.

Now that we have a panel model that is actually used with Allwinner
hardware, has the same dimensions, and the timings have been shown to
work with the nameless panels, we can use that one instead.

Commit 225da7e65a ("ARM: dts: add eMMC reset line for
exynos4412-odroid-common") added MMC power sequence for eMMC card of
Odroid X2/U3. It reused generic sd1_cd pin control configuration node
and only disabled pull-up. However that time the pinctrl configuration
was not applied during MMC power sequence driver initialization. This
has been changed later by commit d97a1e5d7c ("mmc: pwrseq: convert to
proper platform device").

It turned out then, that the provided pinctrl configuration is not
correct, because the eMMC_RTSN line is being re-configured as 'special
function/card detect function for mmc1 controller' not the simple
'output', thus the power sequence driver doesn't really set the pin
value. This in effect broke the reboot of Odroid X2/U3 boards. Fix this
by providing separate node with eMMC_RTSN pin configuration.

275f22148e ipc: rename old-style shmctl/semctl/msgctl syscalls
The behavior of these system calls is slightly different between
architectures, as determined by the CONFIG_ARCH_WANT_IPC_PARSE_VERSION
symbol. Most architectures that implement the split IPC syscalls don't set
that symbol and only get the modern version, but alpha, arm, microblaze,
mips-n32, mips-n64 and xtensa expect the caller to pass the IPC_64 flag.

For the architectures that so far only implement sys_ipc(), i.e. m68k,
mips-o32, powerpc, s390, sh, sparc, and x86-32, we want the new behavior
when adding the split syscalls, so we need to distinguish between the
two groups of architectures.

The method I picked for this distinction is to have a separate system call
entry point: sys_old_*ctl() now uses ipc_parse_version, while sys_*ctl()
does not. The system call tables of the five architectures are changed
accordingly.

As an additional benefit, we no longer need the configuration specific
definition for ipc_parse_version(), it always does the same thing now,
but simply won't get called on architectures with the modern interface.

A small downside is that on architectures that do set
ARCH_WANT_IPC_PARSE_VERSION, we now have an extra set of entry points
that are never called. They only add a few bytes of bloat, so it seems
better to keep them compared to adding yet another Kconfig symbol.
I considered adding new syscall numbers for the IPC_64 variants for
consistency, but decided against that for now.

Adding the number in arch/arm/ lets us use the system call on arm64
systems in compat mode, and also reduces the number of differences
between architectures. If we want to implement kexec_file_load on ARM
in the future, the number assignment means that kexec tools can already

78594b9599 ARM: add migrate_pages() system call
The migrate_pages system call has an assigned number on all architectures
except ARM. When it got added initially in commit d80ade7b32 ("ARM:
Fix warning: #warning syscall migrate_pages not implemented"), it was
intentionally left out based on the observation that there are no 32-bit
ARM NUMA systems.

However, there are now arm64 NUMA machines that can in theory run 32-bit
kernels (actually enabling NUMA there would require additional work)
as well as 32-bit user space on 64-bit kernels, so that argument is no
longer very strong.

Assigning the number lets us use the system call on 64-bit kernels as well
as providing a more consistent set of syscalls across architectures.

ARM: dts: sun8i-a23-a33: Move NAND controller device node to sort by address
The NAND controller device node was inserted into the wrong position,
probably due to a rebase or merge, as the file's structure does not
provide enough context for git to accurately match the previous device
node block.
