Some users of get_user use the macro with an argument p which
is already specified as static. When using clang this leads to
a duplicate specifier:

Remove the const attribute from the register declaration
to avoid the duplicate const specifier. In a test with ptrace.c
and traps.c (both using get_user with non-const arguments for p)
the generated code was exactly the same.

The root cause of above backtrace is task_lock() which takes a sleeping
lock on -RT.
To fix the issue, move clear_tasks_mm_cpumask() call from __cpu_disable()
to __cpu_die() which is called on the thread which is asking for a target
CPU to be shutdown. In addition, this change restores CPU hotplug
functionality on ARM CPU1 can be unplugged/plugged many times.

NUMREGBYTES (which is used as the size for gdb_regs[]) is incorrectly
based on DBG_MAX_REG_NUM instead of GDB_MAX_REGS. DBG_MAX_REG_NUM
is the number of total registers, while GDB_MAX_REGS is the number
of 'unsigned longs' it takes to serialize those registers. Since
FP registers require 3 'unsigned longs' each, DBG_MAX_REG_NUM is
smaller than GDB_MAX_REGS.
This causes GDB 8.0 give the following error on connect:
"Truncated register 19 in remote 'g' packet"
This also causes the register serialization/deserialization logic
to overflow gdb_regs[], overwriting whatever follows.

ARMv8R/M architecture defines new memory protection scheme - PMSAv8
which is not compatible with PMSAv7.
Key differences to PMSAv7 are:
- Region geometry is defined by base and limit addresses
- Addresses need to be either 32 or 64 byte aligned
- No region priority due to overlapping regions are not allowed
- It is unified, i.e. no distinction between data/instruction regions
- Memory attributes are controlled via MAIR
This patch implements support for PMSAv8 MPU defined by ARMv8R/M
architecture.

This patch postpone MPU activation till __after_proc_init (which is
placed in .text section) rather than doing it in __setup_mpu. It
allows us ignore used-only-once .head.text section while programming
PMSAv8 MPU (for PMSAv7 it stays covered anyway).

Currently, we have mixed code placement between .head.text and .text
depends on configuration we are building:
_text M R(UP) R(SMP)
======================================================
__setup_mpu __HEAD __HEAD text
__after_proc_init __HEAD __HEAD text
__mmap_switched text text text
We are going to support another variant of MPU which is different to
PMSAv7 in sense overlapping MPU regions are not allowed, so this patch
makes boundaries between these sections precise and consistent:
_text M R(UP) R(SMP)
======================================================
__setup_mpu __HEAD __HEAD __HEAD
__after_proc_init text text text
__mmap_switched text text text
Additionally, it paves a path to postpone MPU activation till
__after_proc_init where we do set SCTLR anyway and can return
directly to __mmap_switched.

While testing multi_v7_defconfig with config fragments that makes the
kernel size to grow. The kernel fails to load simple modules, as
reported by kselftest:
[ 34.107620] test_printf: section 4 reloc 2 sym 'memset': relocation
28 out of range (0xbf046044 -> 0xc109f720)
selftests: printf.sh [FAIL]
The problem that is seen when enabling too much in the kernel without
enabling ARM_MODULE_PLTS, is that the top of the kernel gets out of
reach from the bottom of the module area.

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.

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.

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.

The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of
the TBIPA register on LS1021A, which happens to be read-only.
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.

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.

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().
[akpm@linux-foundation.org: simplify page_mapping_file(), per Mike]

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).

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.

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 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

Merge tag 'devicetree-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree updates from Rob Herring:
- Sync dtc to upstream version v1.4.6-9-gaadd0b65c987. This adds a
bunch more warnings (hidden behind W=1).
- Build dtc lexer and parser files instead of using shipped versions.
- Rework overlay apply API to take an FDT as input and apply overlays
in a single step.
- Add a phandle lookup cache. This improves boot time by hundreds of
msec on systems with large DT.
- Add trivial mcp4017/18/19 potentiometers bindings.
- Remove VLA stack usage in DT code.

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.

Here is the big set of Staging/IIO driver patches for 4.17-rc1.
It is a lot, over 500 changes, but not huge by previous kernel release
standards. We deleted more lines than we added again (27k added vs. 91k
remvoed), thanks to finally being able to delete the IRDA drivers and
networking code.
We also deleted the ccree crypto driver, but that's coming back in
through the crypto tree to you, in a much cleaned-up form.
Added this round is at lot of "mt7621" device support, which is for an
embedded device that Neil Brown cares about, and of course a handful of
new IIO drivers as well.
And finally, the fsl-mc core code moved out of the staging tree to the
"real" part of the kernel, which is nice to see happen as well.
Full details are in the shortlog, which has all of the tiny cleanup
patches described.
All of these have been in linux-next for a while with no reported
issues.
