"The main thing here is a long-awaited workaround for a CPU erratum on
ThunderX2 which we have developed in conjunction with engineers from

At the moment, the workaround is unconditionally enabled for affected

future if performance numbers show up indicating a significant cost
for real workloads.

Commit 8974558f49 ("mm, page_owner, debug_pagealloc: save and dump
freeing stack trace") enhanced page_owner to also store freeing stack
trace, when debug_pagealloc is also enabled. KASAN would also like to
do this [1] to improve error reports to debug e.g. UAF issues.
Kirill has suggested that the freeing stack trace saving should be also
possible to be enabled separately from KASAN or debug_pagealloc, i.e.
with an extra boot option. Qian argued that we have enough options
already, and avoiding the extra overhead is not worth the complications
in the case of a debugging option. Kirill noted that the extra stack
handle in struct page_owner requires 0.1% of memory.
This patch therefore enables free stack saving whenever page_owner is
enabled, regardless of whether debug_pagealloc or KASAN is also enabled.
KASAN kernels booted with page_owner=on will thus benefit from the
improved error reports.

Miguel Ojeda comments on the eventual [[fallthrough]] syntax:
"Note that C17/C18 does not have [[fallthrough]].
C++17 introduced it, as it is mentioned above. I would keep the
__attribute__((fallthrough)) -> [[fallthrough]] change you did,
though, since that is indeed the standard syntax (given the paragraph
references C++17).
I was told by Aaron Ballman (who is proposing them for C) that it is
more or less likely that it becomes standardized in C2x. However, it
is still not added to the draft (other attributes are already,
though). See N2268 and N2269:

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"A larger-than-usual batch of arm64 fixes for -rc3.
The bulk of the fixes are dealing with a bunch of issues with the
build system from the compat vDSO, which unfortunately led to some
significant Makefile rework to manage the horrible combinations of
toolchains that we can end up needing to drive simultaneously.
We came close to disabling the thing entirely, but Vincenzo was quick
to spin up some patches and I ended up picking up most of the bits
that were left [*]. Future work will look at disentangling the header
files properly.
Other than that, we have some important fixes all over, including one
papering over the miscompilation fallout from forcing
CONFIG_OPTIMIZE_INLINING=y, which I'm still unhappy about. Harumph.
We've still got a couple of open issues, so I'm expecting to have some
more fixes later this cycle.
Summary:
- Numerous fixes to the compat vDSO build system, especially when
combining gcc and clang
- Fix parsing of PAR_EL1 in spurious kernel fault detection
- Partial workaround for Neoverse-N1 erratum #1542419
- Fix IRQ priority masking on entry from compat syscalls
- Fix advertisment of FRINT HWCAP to userspace

This Kselftest update for Linux 5.4-rc3 consists fixes for existing
tests and the framework. Cristian Marussi's patches add ability to
skip targets (tests) and exclude tests that didn't build from run-list.
These patches improve the Kselftest results. Ability to skip targets
helps avoid running tests that aren't supported in certain environments.
As an example, bpf tests from mainline aren't supported on stable kernels
and have dependency on bleeding edge llvm. Being able to skip bpf on
systems that can't meet this llvm dependency will be helpful.
Kselftest can be built and installed from the main Makefile. This change
help simplify Kselftest use-cases which addresses request from users.
Kees Cook added per test timeout support to limit individual test run-time.
