The GPIO mockup selftests are overly complicated with separate
implementations of the tests for sysfs and cdev uAPI, and with the cdev
implementation being dependent on tools/gpio and libmount.
Rework the test implementation to provide a common test suite with a
simplified pluggable uAPI interface. The cdev implementation utilises
the GPIO uAPI directly to remove the dependence on tools/gpio.
The simplified uAPI interface removes the need for any file system mount
checks in C, and so removes the dependence on libmount.
The rework also fixes the sysfs test implementation which has been broken
since the device created in the multiple gpiochip case was split into
separate devices.

Pull libnvdimm fixes from Dan Williams:
"A fix for a crash scenario that has been present since the initial
merge, a minor regression in sysfs attribute visibility, and a fix for
some flexible array warnings.
The bulk of this pull is an update to the libnvdimm unit test
infrastructure to test non-ACPI platforms. Given there is zero
regression risk for test updates, and the tests enable validation of
bits headed towards the next merge window, I saw no reason to hold the
new tests back. Santosh originally submitted this before the v5.11
window opened.
Summary:
- Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
- Fix a regression in 'resource' attribute visibility necessary for
mapping badblocks and other physical address interrogations.
- Fix some flexible array warnings
- Expand the unit test infrastructure for non-ACPI platforms"

Michael Kerrisk suggested that, from an API perspective, it is a bad
idea to share the PR_SYS_DISPATCH_ defines between the prctl operation
and the selector variable.
Therefore, define two new constants to be used by SUD's selector variable
and update the corresponding documentation and test cases.
While this changes the API syscall user dispatch has never been part of a
Linux release, it will show up for the first time in 5.11.

The original code put five u32 before a u64 expansion[10] array. Five is
odd, this will cause trouble in the extension of the structure by adding
new features. This patch moves to use u8 for reserved field to avoid
future alignment risk.
Meanwhile, it also clears the memory of struct map_benchmark in tools,
otherwise, if users use old version to run on newer kernel, the random
expansion value will cause side effect on newer kernel.

The current test module cannot be used for testing platforms (make check)
that do not have support for NFIT. In order to get the ndctl tests working,
we need a module which can emulate NVDIMM devices without relying on
ACPI/NFIT.
The aim of this proposed module is to implement a similar functionality to
the existing module but without the ACPI dependencies.
This RFC series is split into reviewable and compilable chunks.
This patch adds a new driver and registers two nvdimm bus needed for ndctl
make check.

Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
little endian mode. That breaks compilation of our alignment handler
test:

/tmp/cco4l14N.s:1440: Error: `lmw' invalid when little-endian
/tmp/cco4l14N.s:1814: Error: `stmw' invalid when little-endian
make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1
These tests do pass on little endian machines, as the kernel will
still emulate those instructions even when running little
endian (which is arguably a kernel bug).
But we don't really need to test that case, so ifdef those
instructions out to get the alignment test building again.

LinuxSourceTree will unceremoniously crash if the user doesn't call
read_kunitconfig() first in a number of functions.
And currently every place we create an instance, the caller also calls
create_kunitconfig() and read_kunitconfig().
Move these instead into __init__() so they can't be forgotten and to
reduce copy-paste.
The https://github.com/google/pytype type-checker complained that
_config wasn't initialized. With this, kunit_tool now type checks
under both pytype and mypy.
Add an optional boolean that can be used to disable this for use cases
in the future where we might not need/want to load the config.

The authors of this tool were more familiar with a different
type-checker, https://github.com/google/pytype.
That's open source, but mypy seems more prevalent (and runs faster).
And unlike pytype, mypy doesn't try to infer types so it doesn't check
unanotated functions.
So annotate ~all functions in kunit tool to increase type-checking
coverage.
Note: per https://www.python.org/dev/peps/pep-0484/, `__init__()` should
be annotated as `-> None`.
Doing so makes mypy discover a number of new violations.

raw_tracepoint caused by too big ctx_size_in, from Song Liu.
6) Fix LLVM code generation issues with verifier where PTR_TO_MEM{,_OR_NULL}

- Set the minimum GCC version to 5.1 for arm64 due to earlier compiler
bugs.
- Make atomic helpers __always_inline to avoid a section mismatch when
compiling with clang.
- Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the
arm64_dma32_phys_limit variable, no longer needed with a dynamic
ZONE_DMA sizing in 5.11).
- Remove redundant IRQ flag tracing that was leaving lockdep
inconsistent with the hardware state.
- Revert perf events based hard lockup detector that was causing
smp_processor_id() to be called in preemptible context.
- Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to
PT_REGS_SIZE, function prototypes added.

Pull networking fixes from Jakub Kicinski:
"We have a few fixes for long standing issues, in particular Eric's fix
to not underestimate the skb sizes, and my fix for brokenness of
register_netdevice() error path. They may uncover other bugs so we
will keep an eye on them. Also included are Willem's fixes for
kmap(_atomic).
Looking at the "current release" fixes, it seems we are about one rc
behind a normal cycle. We've previously seen an uptick of "people had
run their test suites" / "humans actually tried to use new features"
fixes between rc2 and rc3.
Summary:
Current release - regressions:
- fix feature enforcement to allow NETIF_F_HW_TLS_TX if IP_CSUM &&
IPV6_CSUM
- dcb: accept RTM_GETDCB messages carrying set-like DCB commands if
user is admin for backward-compatibility
- selftests/tls: fix selftests build after adding ChaCha20-Poly1305
Current release - always broken:
- ppp: fix refcount underflow on channel unbridge
- bnxt_en: clear DEFRAG flag in firmware message when retry flashing
- smc: fix out of bound access in the new netlink interface
Previous releases - regressions:
- fix use-after-free with UDP GRO by frags
- mptcp: better msk-level shutdown
- rndis_host: set proper input size for OID_GEN_PHYSICAL_MEDIUM
request
- i40e: xsk: fix potential NULL pointer dereferencing
Previous releases - always broken:
- skb frag: kmap_atomic fixes
- avoid 32 x truesize under-estimation for tiny skbs
- fix issues around register_netdevice() failures
- udp: prevent reuseport_select_sock from reading uninitialized socks
- dsa: unbind all switches from tree when DSA master unbinds
- dsa: clear devlink port type before unregistering slave netdevs
- can: isotp: isotp_getname(): fix kernel information leak
- mlxsw: core: Thermal control fixes
- ipv6: validate GSO SKB against MTU before finish IPv6 processing
- stmmac: use __napi_schedule() for PREEMPT_RT

Add a test to check that the verifier is able to recognize spilling of
PTR_TO_MEM registers, by reserving a ringbuf buffer, forcing the spill
of a pointer holding the buffer address to the stack, filling it back
in from the stack and writing to the memory area pointed by it.
The patch was partially contributed by CyberArk Software, Inc.

It was found in [1] that bpf_inode_storage_get helper did not check
the nullness of the passed owner ptr which caused an oops when
dereferenced. This change incorporates the example suggested in [1] into
the local storage selftest.
The test is updated to create a temporary directory instead of just
using a tempfile. In order to replicate the issue this copied rm binary
is renamed tiggering the inode_rename with a null pointer for the
new_inode. The logic to verify the setting and deletion of the inode
local storage of the old inode is also moved to this LSM hook.
The change also removes the copy_rm function and simply shells out
to copy files and recursively delete directories and consolidates the
logic of setting the initial inode storage to the bprm_committed_creds
hook and removes the file_open hook.
