d8491223bc ARM: SoC fixes
A collection of fixes from the last few weeks. Most of them are smaller
 tweaks and fixes to DT and hardware descriptions for boards. Some of the
 more significant ones are:
 
  - eMMC and RGMII stability tweaks for rk3288
  - DDC fixes for Rock PI 4
  - Audio fixes for two TI am335x eval boards
  - D_CAN clock fix for am335x
  - Compilation fixes for clang
  - !SMP compilation fix for one of the new platforms this release (milbeaut)
  - A revert of a gpio fix for nomadik that instead was fixed in the gpio
    subsystem
  - Whitespace fix for the DT JSON schema (no tabs allowed)

9a8f32038a ARM: milbeaut: fix build with !CONFIG_HOTPLUG_CPU
When HOTPLUG_CPU is disabled, some fields in the smp operations
are not available or needed:

arch/arm/mach-milbeaut/platsmp.c:90:3: error: field designator 'cpu_die' does not refer to any field in type
      'struct smp_operations'
        .cpu_die                = m10v_cpu_die,

      'struct smp_operations'
        .cpu_kill               = m10v_cpu_kill,
         ^

Hide them in an #ifdef like the other platforms do.

2125801ccc ARM: iop: don't use using 64-bit DMA masks
clang warns about statically defined DMA masks from the DMA_BIT_MASK
macro with length 64:

 arch/arm/mach-iop13xx/setup.c:303:35: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
 static u64 iop13xx_adma_dmamask = DMA_BIT_MASK(64);

                                                      ^ ~~~

The ones in iop shouldn't really be 64 bit masks, so changing them
to what the driver can support avoids the warning.

This reverts commit fa9463564e.

Per Linus Walleij:

Dear ARM SoC maintainers,

can you please revert this patch. It was the wrong solution to the
wrong problem, and I must have acted in stress. Andrey fixed the
real bug in a proper way in these commits:

commit e5545c94e4
"gpio: of: Check propname before applying "cs-gpios" quirks"

32d9258662 syscalls: Remove start and number from syscall_set_arguments() args
After removing the start and count arguments of syscall_get_arguments() it
seems reasonable to remove them from syscall_set_arguments(). Note, as of
today, there are no users of syscall_set_arguments(). But we are told that
there will be soon. But for now, at least make it consistent with
syscall_get_arguments().

b35f549df1 syscalls: Remove start and number from syscall_get_arguments() args
At Linux Plumbers, Andy Lutomirski approached me and pointed out that the
function call syscall_get_arguments() implemented in x86 was horribly
written and not optimized for the standard case of passing in 0 and 6 for
the starting index and the number of system calls to get. When looking at
all the users of this function, I discovered that all instances pass in only
0 and 6 for these arguments. Instead of having this function handle
different cases that are never used, simply rewrite it to return the first 6
arguments of a system call.

This should help out the performance of tracing system calls by ptrace,
ftrace and perf.

3d9683cf3b KVM: export <linux/kvm_para.h> and <asm/kvm_para.h> iif KVM is supported
I do not see any consistency about headers_install of <linux/kvm_para.h>
and <asm/kvm_para.h>.

According to my analysis of Linux 5.1-rc1, there are 3 groups:

 [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported

    alpha, arm, hexagon, mips, powerpc, s390, sparc, x86

 [2] <asm/kvm_para.h> is exported, but <linux/kvm_para.h> is not

    arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc,
    parisc, sh, unicore32, xtensa

 [3] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported

    csky, nds32, riscv

This does not match to the actual KVM support. At least, [2] is
half-baked.

Nor do arch maintainers look like they care about this. For example,
commit 0add53713b ("microblaze: Add missing kvm_para.h to Kbuild")
exported <asm/kvm_para.h> to user-space in order to fix an in-kernel
build error.

We have two ways to make this consistent:

 [A] export both <linux/kvm_para.h> and <asm/kvm_para.h> for all
     architectures, irrespective of the KVM support

 [B] Match the header export of <linux/kvm_para.h> and <asm/kvm_para.h>
     to the KVM support

My first attempt was [A] because the code looks cleaner, but Paolo
suggested [B].

So, this commit goes with [B].

For most architectures, <asm/kvm_para.h> was moved to the kernel-space.
I changed include/uapi/linux/Kbuild so that it checks generated
asm/kvm_para.h as well as check-in ones.

After this commit, there will be two groups:

 [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported

    arm, arm64, mips, powerpc, s390, x86

 [2] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported

    alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze,
    nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa

fa9463564e ARM: dts: nomadik: Fix polarity of SPI CS
The SPI DT bindings are for historical reasons a pitfall,
the ability to flag a GPIO line as active high/low with
the second cell flags was introduced later so the SPI
subsystem will only accept the bool flag spi-cs-high
to indicate that the line is active high.

It worked by mistake, but the mistake was corrected
in another commit.

The comment in the DTS file was also misleading: this
CS is indeed active high.

We rely on the mmu_notifier call backs to handle the split/merge
of huge pages and thus we are guaranteed that, while creating a
block mapping, either the entire block is unmapped at stage2 or it
is missing permission.

However, we miss a case where the block mapping is split for dirty
logging case and then could later be made block mapping, if we cancel the
dirty logging. This not only creates inconsistent TLB entries for
the pages in the the block, but also leakes the table pages for
PMD level.

Handle this corner case for the huge mappings at stage2 by
unmapping the non-huge mapping for the block. This could potentially
release the upper level table. So we need to restart the table walk
once we unmap the range.

a6ecfb11bf KVM: arm/arm64: vgic-its: Take the srcu lock when writing to guest memory
When halting a guest, QEMU flushes the virtual ITS caches, which
amounts to writing to the various tables that the guest has allocated.

When doing this, we fail to take the srcu lock, and the kernel
shouts loudly if running a lockdep kernel:

fixed at the same time, but hey...

91740fc824 ARM: imx6q: cpuidle: fix bug that CPU might not wake up at expected time
In the current cpuidle implementation for i.MX6q, the CPU that sets
'WAIT_UNCLOCKED' and the CPU that returns to 'WAIT_CLOCKED' are always
the same. While the CPU that sets 'WAIT_UNCLOCKED' is in IDLE state of
"WAIT", if the other CPU wakes up and enters IDLE state of "WFI"
istead of "WAIT", this CPU can not wake up at expired time.
 Because, in the case of "WFI", the CPU must be waked up by the local
timer interrupt. But, while 'WAIT_UNCLOCKED' is set, the local timer
is stopped, when all CPUs execute "wfi" instruction. As a result, the
local timer interrupt is not fired.
 In this situation, this CPU will wake up by IRQ different from local
timer. (e.g. broacast timer)

So, this fix changes CPU to return to 'WAIT_CLOCKED'.

1a7ee0efb2 ARM: dts: imx6dl-yapp4: Use rgmii-id phy mode on the cpu port
Use rgmii-id phy mode for the CPU port (MAC0) of the QCA8334 switch
to add delays to both Tx and Rx clock.

It worked with the rgmii mode before because the qca8k driver
(incorrectly) enabled delays in that mode and rgmii-id was not
implemented at all.

Commit 5ecdd77c61 ("net: dsa: qca8k: disable delay for RGMII mode")
removed the delays from the RGMII mode and hence broke the networking.

To fix the problem, commit a968b5e9d5 ("net: dsa: qca8k: Enable delay
for RGMII_ID mode") was introduced.

Now the correct phy mode is available so use it.

8dbc4d5ddb ARM: dts: rockchip: Fix SD card detection on rk3288-tinker
The Problem:

On ASUS Tinker Board S, when booting from the eMMC, and there is card
in the sd slot, there are constant errors.

Also when warm reboot, uboot can not access the sd slot

Cause:

Identified by Robin Murphy @ ARM. The Card Detect on rk3288
devices is pulled up by vccio-sd; so when the regulator powers this
off, card detect gives spurious errors. A second problem, is during
power down, vccio-sd apprears to be powered down. This causes a
problem when warm rebooting from the sd card. This was identified by
Jonas Karlman.

History:

A common fault on these rk3288 board, which impliment the reference
design.

When this arose before:

http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/281153.html

And Ulf and Jaehoon clearly said this was a broken card detect design,
which should be solved via polling

Solution:

Hence broken-cd is set as a property. This cures the errors. The
powering down of vccio-sd during reboot is cured by adding
regulator-boot-on.

This solutions has been fairly widely reviewed and tested.

 - Remove the printing of the virtual memory layout, which is no longer
   useful since we hide pointers.
 - Correct SCU help text.
 - Remove legacy TWD registration method.
 - Add pgprot_device() implementation for mapping PCI sysfs resource
   files.
 - Initialise PFN limits earlier for kmemleak.
 - Fix argument count to match macro definition (affects clang builds)
 - Use unified assembler language almost everywhere for clang, and
   other clang improvements (from Stefan Agner, Nathan Chancellor).
 - Support security extension for noMMU and other noMMU cleanups
   (from Vladimir Murzin).
 - Remove unnecessary SMP bringup code (which was incorrectly copy'n'
   pasted from the ARM platform implementations) and remove it from
   the arch code to discourge further copys of it appearing.
 - Add Cortex A9 erratum preventing kexec working on some SoCs.
 - AMBA bus identification updates from Mike Leach.
 - More use of raw spinlocks to avoid -RT kernel issues
   (from Yang Shi and Sebastian Andrzej Siewior).
