Pull SELinux updates from Paul Moore:
"Nine SELinux patches for v5.1, all bug fixes.
As far as I'm concerned, nothing really jumps out as risky or special
to me, but each commit has a decent description so you can judge for
yourself. As usual, everything passes the selinux-testsuite; please
merge for v5.1"

Pull security subsystem updates from James Morris:
- Extend LSM stacking to allow sharing of cred, file, ipc, inode, and
task blobs. This paves the way for more full-featured LSMs to be
merged, and is specifically aimed at LandLock and SARA LSMs. This
work is from Casey and Kees.
- There's a new LSM from Micah Morton: "SafeSetID gates the setid
family of syscalls to restrict UID/GID transitions from a given
UID/GID to only those approved by a system-wide whitelist." This
feature is currently shipping in ChromeOS.

Pull percpu updates from Dennis Zhou:
"There are 2 minor changes to the percpu allocator this merge window:
- for loop condition that could be out of bounds on multi-socket UP
- cosmetic removal of pcpu_group_offsets[0] in UP code as it is 0
There has been an interest in having better alignment with percpu
allocations. This has caused a performance regression in at least one
reported workload. I have a series out which adds scan hints to the
allocator as well as some other performance oriented changes. I hope
to have this queued for v5.2 soon"

Pull tracing fix/cleanup from Steven Rostedt:
"This is a "pre-pull". It's only one small fix and one small clean up.
I'm testing a few small patches for my real pull request which will
come at a later time. The second patch depends on your tree anyway so
I included it along with the urgent fix.
A small fix Pavel sent me back in august was accidentally lost due to
it being placed with some other patches that failed some tests, and
was rebased out of my local tree. Which was a regression that caused
event filters not to handle negative numbers.
The clean up is from Masami that realized that the code in kprobes
that calls probe_mem_read() wrapper, which is to be used in code used
by both kprobes and uprobes, was only in code for kprobes. It should
not use the wrapper there, but instead call probe_kernel_read()
directly"

Pull xfs updates from Darrick Wong:
"Here are a number of new features and bug fixes for 5.1
They've undergone a week's worth of fstesting and merge cleanly with
master as of this morning
Most of the changes center on improving metadata validation and fixing
problems with online fsck, though there's also a new cache to speed up
unlinked inode handling and cleanup of the copy on write code in
preparation for future features
Changes for Linux 5.1:
- Fix online fsck to handle inode btrees correctly on 64k block
filesystems
- Teach online fsck to check directory and attribute names for
invalid characters
- Miscellanous fixes for online fsck
- Introduce a new panic mask so that we can halt immediately on
metadata corruption (for debugging purposes)
- Fix a block mapping race during writeback
- Cache unlinked inode list backrefs in memory to speed up list
processing
- Separate the bnobt/cntbt and inobt/finobt buffer verifiers so that
we can detect crosslinked btrees
- Refactor magic number verification so that we can standardize it
- Strengthen ondisk metadata structure offset build time verification
- Fix a memory corruption problem in the listxattr code
- Fix a shutdown problem during log recovery due to unreserved finobt
expansion
- Fix a referential integrity problem where O_TMPFILE inodes were put
on the unlinked list with nlink > 0 which would cause asserts
during log recovery if the system went down immediately
- Refactor the delayed allocation allocator to be more clever about
the possibility that its mapping might be stale
- Various fixes to the copy on write mechanism
- Make CoW preallocation suitable for use even with writes that
wouldn't otherwise require it
- Refactor an internal API
- Fix some statx implementation bugs
- Fix miscellaneous compiler and static checker complaints"
* tag 'xfs-5.1-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (70 commits)

Pull btrfs updates from David Sterba:
"This contains usual mix of new features, core changes and fixes; full
list below. I'm planning second pull request, with a few more fixes
that arrived recently but too close to merge window, will send it next
week.
New features:
- support zstd compression levels
- new ioctl to unregister a device from the module (ie. reverse of
device scan)
- scrub prints a message to log when it's about to start or finish
Core changes:
- qgroups can now skip part of a tree that does not get updated
during relocation, because this does not affect the quota
accounting, estimated speedup in run time is about 20%
- the compression workspace management had to be enhanced due to zstd
requirements
- various enospc fixes, when there's high fragmentation the
over-reservation can cause ENOSPC that might not happen after a
flush, in such cases try to wait if the situation improves
Fixes:
- various ioctls could overwrite previous return value if
copy_to_user fails, fix this so the original error is reported
- more reclaim vs GFP_KERNEL fixes
- other cleanups and refactoring
- fix a (valid) lockdep warning in a test when device replace is
destroying worker threads
- make qgroup async transaction commit more aggressive, this avoids
some 'quota limit reached' errors if there are not enough data to
trigger transaction in order to flush
- fix deadlock between snapshot deletion and quotas when backref
walking is called from context that already holds the same locks
- fsync fixes:
- fix fsync after succession of renames of different files
- fix fsync after succession of renames and unlink/rmdir"

The pm8xxx_get_channel() implementation is unclear, and causes gcc to
suddenly generate odd warnings. The trigger for the warning (at least
for me) was the entirely unrelated commit 79a4e91d1bb2 ("device.h: Add
__cold to dev_<level> logging functions"), which apparently changes gcc
code generation in the caller function enough to cause this:
drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’:
drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
&read_nomux_rsv4, true);
~~~~~~~~~~~~~~~~~~~~~~~
drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here
struct pm8xxx_chan_info *ch;
^~
because gcc for some reason then isn't able to see that the termination
condition for the "for( )" loop in that function is also the condition
for returning NULL.
So it's not _actually_ uninitialized, but the function is admittedly
just unnecessarily oddly written.
Simplify and clarify the function, making gcc also see that it always
returns a valid initialized value.

Pull ARM new SoC family support from Arnd Bergmann:
"Two new SoC families are added this time.
Sugaya Taichi submitted support for the Milbeaut SoC family from
Socionext and explains:
"SC2000 is a SoC of the Milbeaut series. equipped with a DSP
optimized for computer vision. It also features advanced
functionalities such as 360-degree, real-time spherical stitching
with multi cameras, image stabilization for without mechanical
gimbals, and rolling shutter correction. More detail is below:
https://www.socionext.com/en/products/assp/milbeaut/SC2000.html"
Interestingly, this one has a history dating back to older chips made
by Socionext and previously Matsushita/Panasonic based on their own
mn10300 CPU architecture that was removed from the kernel last year.
Manivannan Sadhasivam adds support for another SoC family, this is the
Bitmain BM1880 chip used in the Sophon Edge TPU developer board.
The chip is intended for Deep Learning applications, and comes with
dual-core Arm Cortex-A53 to run Linux as well as a RISC-V
microcontroller core to control the tensor unit. For the moment, the
TPU is not accessible in mainline Linux, so we treat it as a generic
Arm SoC.

These are actual commercial products we now support with an in-kernel
device tree source file:
- Bosch Guardian is a product made by Bosch Power Tools GmbH, based
on the Texas Instruments AM335x chip

baseboard management controller. This is for running on the BMC.
- Zodiac Digital Tapping Unit, apparently a kind of ethernet switch
used in airplanes.
- Phicomm K3 is a WiFi router based on Broadcom bcm47094
- Methode Electronics uDPU FTTdp distribution point unit
- X96 Max, a generic TV box based on Amlogic G12a (S905X2)
- NVIDIA Shield TV (Darcy) based on Tegra210
And then there are several new SBC, evaluation, development or modular
systems that we add:
- Three new Rockchips rk3399 based boards:
- FriendlyElec NanoPC-T4 and NanoPi M4
- Radxa ROCK Pi 4
- Five new i.MX6 family SoM modules and boards for industrial
products:
- Logic PD i.MX6QD SoM and evaluation baseboad

in 96boards form factor
- Arm Fixed Virtual Platforms(FVP) Base RevC, a purely virtual
platform for corresponding to the latest "fast model"
- Another Raspberry Pi variant: Model 3 A+, supported both in 32-bit
and 64-bit mode.
- Oxalis Evalkit V100 based on NXP Layerscape LS1012a, in 96Boards
enterprise form factor
- Elgin RV1108 R1 development board based on 32-bit Rockchips RV1108
For already supported boards and SoCs, we often add support for new
devices after merging the drivers. This time, the largest changes
include updates for
- STMicroelectronics stm32mp1, which was now formally launched last
week
- Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
- Action Semi S700
- TI AM654x, their recently merged 64-bit SoC from the OMAP family
- Various Amlogic Meson SoCs
- Mediatek MT2712
- NVIDIA Tegra186 and Tegra210

Pull locking updates from Ingo Molnar:
"The biggest part of this tree is the new auto-generated atomics API
wrappers by Mark Rutland.
The primary motivation was to allow instrumentation without uglifying
the primary source code.
The linecount increase comes from adding the auto-generated files to
the Git space as well:
include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++--
include/asm-generic/atomic-long.h | 1174 ++++++++++---
include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++
include/linux/atomic.h | 1241 +------------
I preferred this approach, so that the full call stack of the (already
complex) locking APIs is still fully visible in 'git grep'.
But if this is excessive we could certainly hide them.
There's a separate build-time mechanism to determine whether the
headers are out of date (they should never be stale if we do our job
right).
Anyway, nothing from this should be visible to regular kernel
developers.
Other changes:
- Add support for dynamic keys, which removes a source of false
positives in the workqueue code, among other things (Bart Van
Assche)
- Updates to tools/memory-model (Andrea Parri, Paul E. McKenney)
- qspinlock, wake_q and lockdep micro-optimizations (Waiman Long)

When using mremap() syscall in addition to MREMAP_FIXED flag, mremap()
calls mremap_to() which does the following:
1) unmaps the destination region where we are going to move the map
2) If the new region is going to be smaller, we unmap the last part
of the old region
Then, we will eventually call move_vma() to do the actual move.
move_vma() checks whether we are at least 4 maps below max_map_count
before going further, otherwise it bails out with -ENOMEM. The problem
is that we might have already unmapped the vma's in steps 1) and 2), so
it is not possible for userspace to figure out the state of the vmas
after it gets -ENOMEM, and it gets tricky for userspace to clean up
properly on error path.
While it is true that we can return -ENOMEM for more reasons (e.g: see
may_expand_vm() or move_page_tables()), I think that we can avoid this
scenario if we check early in mremap_to() if the operation has high
chances to succeed map-wise.
Should that not be the case, we can bail out before we even try to unmap
anything, so we make sure the vma's are left untouched in case we are
likely to be short of maps.
The thumb-rule now is to rely on the worst-scenario case we can have.
That is when both vma's (old region and new region) are going to be
split in 3, so we get two more maps to the ones we already hold (one per
each). If current map count + 2 maps still leads us to 4 maps below the
threshold, we are going to pass the check in move_vma().
Of course, this is not free, as it might generate false positives when
it is true that we are tight map-wise, but the unmap operation can
release several vma's leading us to a good state.
Another approach was also investigated [1], but it may be too much
hassle for what it brings.

LTP testcase mtest06 [1] can trigger a crash on s390x running 5.0.0-rc8.
This is a stress test, where one thread mmaps/writes/munmaps memory area
and other thread is trying to read from it:
CPU: 0 PID: 2611 Comm: mmap1 Not tainted 5.0.0-rc8+ #51

page_table_free() is called with NULL mm parameter, but because "0" is a
valid address on s390 (see S390_lowcore), it keeps going until it
eventually crashes in lockdep's lock_acquire. This crash is
reproducible at least since 4.14.
Problem is that "vmf->vma" used in do_fault() can become stale. Because
mmap_sem may be released, other threads can come in, call munmap() and
cause "vma" be returned to kmem cache, and get zeroed/re-initialized and
re-used:
handle_mm_fault |
__handle_mm_fault |
do_fault |
vma = vmf->vma |
do_read_fault |
__do_fault |
vma->vm_ops->fault(vmf); |

Cache mm_struct to avoid using potentially stale "vma".
