c29fd48911 ARM: dts: dra7: Add high speed modes capability to MMC1/MMC2 dt node
While the supported UHS mode can be obtained from CAPA2
register, SD Host Controller Standard Specification
doesn't define bits for MMC's HS200 and DDR mode capability.
Add properties to indicate MMC HS200 and DDR speed mode capability in
dt node.

The wilink module is a combo wireless connectivity sdio
card based on Texas Instrument's wl18xx solution. It is a
4-wire, 1.8V, embedded sdio wlan device with an external
irq line and is power-controlled by a gpio-based fixed
regulator.

ca2618b5d5 ARM: dts: dra7-mmc-iodelay: Add a new pinctrl group for clk line without pullup
During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.

According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.

In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.

Add a new pinctrl group for clock line without pullup to be used in boards
where mmc1_clk line is not connected to an external pullup.

85bd0ba1ff arm/arm64: KVM: Add PSCI version selection API
Although we've implemented PSCI 0.1, 0.2 and 1.0, we expose either 0.1
or 1.0 to a guest, defaulting to the latest version of the PSCI
implementation that is compatible with the requested version. This is
no different from doing a firmware upgrade on KVM.

But in order to give a chance to hypothetical badly implemented guests
that would have a fit by discovering something other than PSCI 0.2,
let's provide a new API that allows userspace to pick one particular
version of the API.

This is implemented as a new class of "firmware" registers, where
we expose the PSCI version. This allows the PSCI version to be
save/restored as part of a guest migration, and also set to
any supported version if the guest requires it.

2dd8a62c64 linux/const.h: move UL() macro to include/linux/const.h
ARM, ARM64 and UniCore32 duplicate the definition of UL():

  #define UL(x) _AC(x, UL)

This is not actually arch-specific, so it will be useful to move it to a
common header.  Currently, we only have the uapi variant for
linux/const.h, so I am creating include/linux/const.h.

I also added _UL(), _ULL() and ULL() because _AC() is mostly used in
the form either _AC(..., UL) or _AC(..., ULL).  I expect they will be
replaced in follow-up cleanups.  The underscore-prefixed ones should
be used for exported headers.

8f2af155b5 exec: pass stack rlimit into mm layout functions
Patch series "exec: Pin stack limit during exec".

Attempts to solve problems with the stack limit changing during exec
continue to be frustrated[1][2].  In addition to the specific issues
around the Stack Clash family of flaws, Andy Lutomirski pointed out[3]
other places during exec where the stack limit is used and is assumed to
be unchanging.  Given the many places it gets used and the fact that it
can be manipulated/raced via setrlimit() and prlimit(), I think the only
way to handle this is to move away from the "current" view of the stack
limit and instead attach it to the bprm, and plumb this down into the
functions that need to know the stack limits.  This series implements
the approach.

[1] 04e35f4495 ("exec: avoid RLIMIT_STACK races with prlimit()")
[2] 779f4e1c6c ("Revert "exec: avoid RLIMIT_STACK races with prlimit()"")
[3] to security@kernel.org, "Subject: existing rlimit races?"

This patch (of 3):

Since it is possible that the stack rlimit can change externally during
exec (either via another thread calling setrlimit() or another process
calling prlimit()), provide a way to pass the rlimit down into the
per-architecture mm layout functions so that the rlimit can stay in the
bprm structure instead of sitting in the signal structure until exec is
finalized.

3d2054ad8c ARM: CMA: avoid double mapping to the CMA area if CONFIG_HIGHMEM=y
CMA area is now managed by the separate zone, ZONE_MOVABLE, to fix many
MM related problems.  In this implementation, if CONFIG_HIGHMEM = y,
then ZONE_MOVABLE is considered as HIGHMEM and the memory of the CMA
area is also considered as HIGHMEM.  That means that they are considered
as the page without direct mapping.  However, CMA area could be in a
lowmem and the memory could have direct mapping.

In ARM, when establishing a new mapping for DMA, direct mapping should
be cleared since two mapping with different cache policy could cause
unknown problem.  With this patch, PageHighmem() for the CMA memory
located in lowmem returns true so that the function for DMA mapping
cannot notice whether it needs to clear direct mapping or not,
correctly.  To handle this situation, this patch always clears direct
mapping for such CMA memory.

- https://www.spinics.net/lists/arm-kernel/msg613212.html

After checking again the L2 cache use in the NPCM7xx,
the only L2 cache flag we need to set is L2C_AUX_CTRL_SHARED_OVERRIDE
and it is done in the device tree:
https://patchwork.kernel.org/patch/10063497/

L2 cache flag mask allowed all the flag option.

The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of

Changing TBI PHY address therefore does not work on LS1021A.

The real (and documented) address of the TBIPA registere lies in the eTSEC
block and not in MDIO/MII, which is read/write, so using that fixes
the problem.

54a702f705 kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers
GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.

Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped

A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.

  .SECONDARY
    Prerequisites of this special target are treated as intermediate
    files but are never automatically deleted.

  .PRECIOUS
    When make is interrupted during execution, it may delete the target
    file it is updating if the file was modified since make started.
    If you mark the file as precious, make will never delete the file
    if interrupted.

Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.

The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.

Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.

  .PRECIOUS: $(obj)/%.lex.c

works, but

  .SECONDARY: $(obj)/%.lex.c

has no effect.  However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.

The targets specified as .SECONDARY must be explicit.  $(targets)
contains all targets that need to include .*.cmd files.  So, the
intermediates you want to keep are mostly in there.  Therefore, mark
$(targets) as .SECONDARY.  It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.

I replaced some .SECONDARY / .PRECIOUS markers with 'targets'.  This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

cb9f753a37 mm: fix races between swapoff and flush dcache
Thanks to commit 4b3ef9daa4 ("mm/swap: split swap cache into 64MB
trunks"), after swapoff the address_space associated with the swap
device will be freed.  So page_mapping() users which may touch the
address_space need some kind of mechanism to prevent the address_space
from being freed during accessing.

The dcache flushing functions (flush_dcache_page(), etc) in architecture
specific code may access the address_space of swap device for anonymous
pages in swap cache via page_mapping() function.  But in some cases
there are no mechanisms to prevent the swap device from being swapoff,
for example,

  CPU1					CPU2
  __get_user_pages()			swapoff()
    flush_dcache_page()
      mapping = page_mapping()
        ...				  exit_swap_address_space()
        ...				    kvfree(spaces)
        mapping_mapped(mapping)

The address space may be accessed after being freed.

But from cachetlb.txt and Russell King, flush_dcache_page() only care
about file cache pages, for anonymous pages, flush_anon_page() should be
used.  The implementation of flush_dcache_page() in all architectures
follows this too.  They will check whether page_mapping() is NULL and
whether mapping_mapped() is true to determine whether to flush the
dcache immediately.  And they will use interval tree (mapping->i_mmap)
to find all user space mappings.  While mapping_mapped() and
mapping->i_mmap isn't used by anonymous pages in swap cache at all.

So, to fix the race between swapoff and flush dcache, __page_mapping()
is add to return the address_space for file cache pages and NULL
otherwise.  All page_mapping() invoking in flush dcache functions are
replaced with page_mapping_file().

7bbaf27d9c zboot: fix stack protector in compressed boot phase
Calling __stack_chk_guard_setup() in decompress_kernel() is too late
that stack checking always fails for decompress_kernel() itself.  So
remove __stack_chk_guard_setup() and initialize __stack_chk_guard before
we call decompress_kernel().

Original code comes from ARM but also used for MIPS and SH, so fix them
together.  If without this fix, compressed booting of these archs will
fail because stack checking is enabled by default (>=4.16).

167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

b240b419db ARM: SoC device tree updates for 4.17
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

5f8d561fb0 ARM: decompressor: fix warning introduced in fortify patch
Commit ee333554fe ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
introduced a new warning:

arch/arm/boot/compressed/misc.c: In function 'fortify_panic':
arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror]

The simple solution would be to make 'error' a noreturn function, but
this causes a prototype mismatch as the function is prototyped in
several .c files.  So, move the function prototype to a new header.

There are also a couple of variables that are also declared in several
locations.  Clean this up while we are here.
