__swiotlb_get_sgtable_page and __swiotlb_mmap_pfn are not only misnamed
but also only used if CONFIG_IOMMU_DMA is set.  Just add a simple ifdef
for now, given that we plan to remove them entirely for the next merge

kprobes allocates a writable executable page with module_alloc() in
order to store executable code.
Reworked to that when allocate a page it sets mode RO. Inspired by
commit 63fef14fc9 ("kprobes/x86: Make insn buffer always ROX and use text_poke()").

98356eb0ae arm64: makefile fix build of .i file in external module case
After 'a66649dab350 arm64: fix vdso-offsets.h dependency' if
one will try to build .i file in case of external kernel module,
build fails complaining that prepare0 target is missing. This
issue came up with SystemTap when it tries to build variety
of .i files for its own generated kernel modules trying to
figure given kernel features/capabilities.

The issue is that prepare0 is defined in top level Makefile
only if KBUILD_EXTMOD is not defined. .i file rule depends
on prepare and in case KBUILD_EXTMOD defined top level Makefile
contains empty rule for prepare. But after mentioned commit
arch/arm64/Makefile would introduce dependency on prepare0
through its own prepare target.

Fix it to put proper ifdef KBUILD_EXTMOD around code introduced
by mentioned commit. It matches what top level Makefile does.

Merge tag 'stackleak-v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull stackleak gcc plugin from Kees Cook:
 "Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
  was ported from grsecurity by Alexander Popov. It provides efficient
  stack content poisoning at syscall exit. This creates a defense
  against at least two classes of flaws:

   - Uninitialized stack usage. (We continue to work on improving the
     compiler to do this in other ways: e.g. unconditional zero init was
     proposed to GCC and Clang, and more plugin work has started too).

   - Stack content exposure. By greatly reducing the lifetime of valid
     stack contents, exposures via either direct read bugs or unknown
     cache side-channels become much more difficult to exploit. This
     complements the existing buddy and heap poisoning options, but
     provides the coverage for stacks.

  The x86 hooks are included in this series (which have been reviewed by
  Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
  been merged through the arm64 tree (written by Laura Abbott and
  reviewed by Mark Rutland and Will Deacon).

  With VLAs having been removed this release, there is no need for
  alloca() protection, so it has been removed from the plugin"

7e1c4e2792 memblock: stop using implicit alignment to SMP_CACHE_BYTES
When a memblock allocation APIs are called with align = 0, the alignment
is implicitly set to SMP_CACHE_BYTES.

Implicit alignment is done deep in the memblock allocator and it can
come as a surprise.  Not that such an alignment would be wrong even
when used incorrectly but it is better to be explicit for the sake of
clarity and the prinicple of the least surprise.

Replace all such uses of memblock APIs with the 'align' parameter
explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment
in the memblock internal allocation functions.

For the case when memblock APIs are used via helper functions, e.g.  like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where
appropriate.

The direct memblock APIs users were updated using the semantic patch below:

9a8dd708d5 memblock: rename memblock_alloc{_nid,_try_nid} to memblock_phys_alloc*
Make it explicit that the caller gets a physical address rather than a
virtual one.

This will also allow using meblock_alloc prefix for memblock allocations
returning virtual address, which is done in the following patches.

The conversion is done using the following semantic patch:

Prefer _THIS_IP_ defined in linux/kernel.h.

a few archs had inline assembly instead.

This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

4b42745211 ARM: SoC platform updates for 4.20
A couple of platforms change hands in the MAINTAINERS file:
 
 - Linus Walleij lists himself for the ARM Reference platforms:
   versatile, vexpress, integrator and realview. He has been the main
   contributor for these for a while, and makes it official now.
 
 - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
 
 - Manivannan Sadhasivam becomes a secondary maintainer for the
   Actions Semi machines
 
 - Nicolas Ferre lists updates the MAINTAINER listing for the AT91
   platform: Ludovic Desroches is now a co-maintainer for the platform, and
   several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
   Codrin Ciubotariu) take over individual device drivers.
 
 Thanks everyone for working on this, and welcome to the new maintainers!
 
 The "virt" platform on qemy or kvm can now be used in big-endian mode
 without additional tricks, thanks to Jason Donenfeld.
 
 Once again, we gain support for another NXP i.MX6 variant, this time
 it's the i.MX 6ULZ 32-bit single-core version.
 
 On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
 and RZ/G2M (r8a774a1). These are described as microcontrollers on the
 manufacturer website, but appear to be rather powerful. The RZ/G2M is
 used on the reference board for the CIP Super Long Term Support (SLTS)
 Linux Kernels.

b22b6beae6 ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
 
 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

53b7a3b7ec ARM: SoC defconfig updates
The defconfig changes are split out from the rest again. This time we
 have a number of changes for NXP i.MX and Renesas, including a cleanup of
 old options.
 
 Some smaller changes are for Socionext Uniphier, Allwinner, Qualcomm,
 Rockchip, Renesas, AT91, Hisilicon, and STM32. All of these just enable
 platform specific device drivers.

93335e5911 ARM: SoC device tree updates for 4.20
There are close to 800 indivudal changesets in this branch again, which
 feels like a lot. There are particularly many changes for the NVIDIA
 Tegra platform this time, in fact more than it has seen in the two years
 since the v4.9 merge window. Aside from this, it's been fairly normal,
 with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi,
 Samsung Exynos, and TI OMAP.
 
 Most of the changes are for adding new features into existing boards,
 for brevity I'm only mentioning completely new machines and SoCs here.
 For the first time I think we have (slightly) more new 64-bit hardware
 than 32-bit:
 
 Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
 computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5
 is a minor variation of the motherboards of the GTA04 phone, see
 https://shop.goldelico.com/wiki.php?page=GTA04A5
 
 Clearfog is a nice little board for quad-core
 Marvell Armada 8040 network processor, see
 https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
 
 Two additional server boards come with the Aspeed baseboard management
 controllers: Stardragon4800 is an arm64 reference platform made by HXT
 (based on Qualcomm's server chips), and TiogaPass is an Open Compute
 mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in
 the BMC.
 
 NXP i.MX usually sees a lot of new boards each release. This time there
 we only add one minor variant: ConnectCore 6UL SBC Pro uses the same
 SoM design as the ConnectCore 6UL SBC Express added later. However,
 there is a new chip, the i.MX6ULZ, which is an even smaller variant
 of the i.MX6ULL, with features removed. There is also support for the
 reference board design, the i.MX6ULZ 14x14 EVK.
 
 A new Raspberry Pi variant gets added, this one is the CM3 compute module
 based on bcm2837, it was launched in early 2017 but only now added to
 the kernel, both as 32-bit and as 64-bit files, as we tend to do for
 Raspberry Pi.
 
 On the Allwinner side, everything is again about cheap development
 boards, usually of the "Fruit Pi" variety. The new ones this time
 are:
 Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
 Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
 Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
 Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
 The last one of these is now a 64-bit version of the earlier Banana
 Pi M2+ H3, with the same board layout.
 
 Similarly, for Rockchips, get get another variant of the 32-bit
 Asus Tinker board, the model 'S' based on rk3288, and three now
 boards based on the popular RK3399 chip:
 ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
 Rock960: https://www.96boards.org/product/rock960/
 RockPro64: https://www.pine64.org/?page_id=61454
 These are all quite powerful boards with lots of RAM and I/O, and
 the RK3399 is the same chip used in several Chromebooks.  Finally,
 we get support for the PX30 (aka rk3326) chip, which is based on the
 low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board
 is supported.
 
 One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based
 on the MT7622 WiFi router platform, and the first product I've seen with
 a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html
 
 For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
 development board, which are similar to the Hi3660 and Hikey 360
 respectively, but add support for an NPU.
 
 Amlogic gets initial support for the Meson-G12A chip (S905D2),
 another quad-core Cortex-A53 SoC, and its evaluation platform.
 On the 32-bit side, we gain support for an actual end-user product,
 the Endless Computers Endless Mini based on Meson8b (S805), see
 https://endlessos.com/computers/
 
 Qualcomm adds support for their MSM8998 SoC and evaluation platform. This
 chip is commonly known as the Snapdragon 835, and is used in high-end
 phones as well as low-end laptops.
 
 For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
 but no boards for this one. However, we do add boards for the previously
 added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB
 Starter Kit Pro.
 
 While we have lots of DT changes for NVIDIA to update the existing files,
 the only board that gets added is the Toradex Colibri T20 on Colibri
 Evaluation Board for the old Tegra2.
 
 Synaptics add support for their AS370 SoC, which is part of the (formerly
 Marvell) Berlin line of set-top-box chips used e.g.  in the various Google
 Chromecast. Only the .dtsi gets added at this point, no actual machines.

d018498ccc hugetlb: harmonize hugetlb.h arch specific defines with pgtable.h
In order to reduce copy/paste of functions across architectures and then
make riscv hugetlb port (and future ports) simpler and smaller, this
patchset intends to factorize the numerous hugetlb primitives that are
defined across all the architectures.

Except for prepare_hugepage_range, this patchset moves the versions that
are just pass-through to standard pte primitives into
asm-generic/hugetlb.h by using the same #ifdef semantic that can be found
in asm-generic/pgtable.h, i.e.  __HAVE_ARCH_***.

s390 architecture has not been tackled in this serie since it does not use
asm-generic/hugetlb.h at all.

This patchset has been compiled on all addressed architectures with
success (except for parisc, but the problem does not come from this
series).

This patch (of 11):

asm-generic/hugetlb.h proposes generic implementations of hugetlb related
functions: use __HAVE_ARCH_HUGE* defines in order to make arch specific
implementations of hugetlb functions consistent with pgtable.h scheme.

19a2ca0fb5 arm64: lib: use C string functions with KASAN enabled
ARM64 has asm implementation of memchr(), memcmp(), str[r]chr(),
str[n]cmp(), str[n]len().  KASAN don't see memory accesses in asm code,
thus it can potentially miss many bugs.

Ifdef out __HAVE_ARCH_* defines of these functions when KASAN is enabled,
so the generic implementations from lib/string.c will be used.

We can't just remove the asm functions because efistub uses them.  And we
can't have two non-weak functions either, so declare the asm functions as
weak.

d1f2b1710d IOMMU Updates for Linux v4.20
These updates bring:
 
 	- Debugfs support for the Intel VT-d driver. When enabled, it
 	  now also exposes some of its internal data structures to
 	  user-space for debugging purposes.
 
 	- ARM-SMMU driver now uses the generic deferred flushing
 	  and fast-path iova allocation code. This is expected to be a
 	  major performance improvement, as this allocation path scales
 	  a lot better.
 
 	- Support for r8a7744 in the Renesas iommu driver
 
 	- Couple of minor fixes and improvements all over the place

ba9f6f8954 Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman:
 "I have been slowly sorting out siginfo and this is the culmination of
  that work.

  The primary result is in several ways the signal infrastructure has
  been made less error prone. The code has been updated so that manually
  specifying SEND_SIG_FORCED is never necessary. The conversion to the
  new siginfo sending functions is now complete, which makes it
  difficult to send a signal without filling in the proper siginfo
  fields.

  At the tail end of the patchset comes the optimization of decreasing
  the size of struct siginfo in the kernel from 128 bytes to about 48
  bytes on 64bit. The fundamental observation that enables this is by
  definition none of the known ways to use struct siginfo uses the extra
  bytes.

  This comes at the cost of a small user space observable difference.
  For the rare case of siginfo being injected into the kernel only what
  can be copied into kernel_siginfo is delivered to the destination, the
  rest of the bytes are set to 0. For cases where the signal and the
  si_code are known this is safe, because we know those bytes are not
  used. For cases where the signal and si_code combination is unknown
  the bits that won't fit into struct kernel_siginfo are tested to
  verify they are zero, and the send fails if they are not.

  I made an extensive search through userspace code and I could not find
  anything that would break because of the above change. If it turns out
  I did break something it will take just the revert of a single change
  to restore kernel_siginfo to the same size as userspace siginfo.

  Testing did reveal dependencies on preferring the signo passed to
  sigqueueinfo over si->signo, so bit the bullet and added the
  complexity necessary to handle that case.

  Testing also revealed bad things can happen if a negative signal
  number is passed into the system calls. Something no sane application
  will do but something a malicious program or a fuzzer might do. So I
  have fixed the code that performs the bounds checks to ensure negative
  signal numbers are handled"
