It is possible for a bulk operation (MA_STATE_BULK is set) to enter the
new_end < mt_min_slots[type] case and set wr_rebalance as a store type.
This is incorrect as bulk stores do not rebalance per write, but rather
after the all of the writes are done through the mas_bulk_rebalance()
path. Therefore, add a check to make sure MA_STATE_BULK is not set before
we return wr_rebalance as the store type.
Also add a test to make sure wr_rebalance is never the store type when
doing bulk operations via mas_expected_entries()
This is a hotfix for this rc however it has no userspace effects as there
are no users of the bulk insertion mode.

Patch series "selftests/mm: fix deadlock after pthread_create".
On Android arm, pthread_create followed by a fork caused a deadlock in the
case where the fork required work to be completed by the created thread.
Update the synchronization primitive to use pthread_barrier instead of
atomic_bool.
Apply the same fix to the wp-fork-with-event test.
This patch (of 2):
Swap synchronization primitive with pthread_barrier, so that stdatomic.h
does not need to be included.
The synchronization is needed on Android ARM64; we see a deadlock with
pthread_create when the parent thread races forward before the child has a
chance to start doing work.

Linking of urandom_read and liburandom_read.so prefers LLVM's 'ld.lld' but
falls back to using 'ld' if unsupported. However, this fallback discards
any existing makefile macro for LD and can break cross-compilation.
Fix by changing the fallback to use the target linker $(LD), passed via
'-fuse-ld=' using an absolute path rather than a linker "flavour".

The hmm2 double_map test was failing due to an incorrect buffer->mirror
size. The buffer->mirror size was 6, while buffer->ptr size was 6 *
PAGE_SIZE. The test failed because the kernel's copy_to_user function was
attempting to copy a 6 * PAGE_SIZE buffer to buffer->mirror. Since the
size of buffer->mirror was incorrect, copy_to_user failed.
This patch corrects the buffer->mirror size to 6 * PAGE_SIZE.

The sched_ext selftests is missing proper cross-compilation support, a
proper target entry, and out-of-tree build support.
When building the kselftest suite, e.g.:
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \
TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \
-C tools/testing/selftests install
or:
make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \
O=/output/foo -C tools/testing/selftests install
The expectation is that the sched_ext is included, cross-built, the
correct toolchain is picked up, and placed into /output/foo.
In contrast to the BPF selftests, the sched_ext suite does not use
bpftool at test run-time, so it is sufficient to build bpftool for the
build host only.
Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext
selftest. Also, remove some variables that were unused by the
Makefile.

Pull kvm fixes from Paolo Bonzini:
"ARM64:
- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail
- Make sure that the host's vector length is at capped by a value
common to all CPUs
- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken
- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

Currently, the second bridge command overwrites the first one.
Fix this by adding this VID to the interface behind $swp2.
The one_bridge_two_pvids() test intends to check that there is no
leakage of traffic between bridge ports which have a single VLAN - the
PVID VLAN.
Because of a typo, port $swp1 is configured with a PVID twice (second
command overwrites first), and $swp2 isn't configured at all (and since
the bridge vlan_default_pvid property is set to 0, this port will not
have a PVID at all, so it will drop all untagged and priority-tagged
traffic).
So, instead of testing the configuration that was intended, we are
testing a different one, where one port has PVID 2 and the other has
no PVID. This incorrect version of the test should also pass, but is
ineffective for its purpose, so fix the typo.
This typo has an impact on results of the test,
potentially leading to wrong conclusions regarding
the functionality of a network device.
The tests results:
TEST: Switch ports in VLAN-aware bridge with different PVIDs:
Unicast non-IP untagged [ OK ]
Multicast non-IP untagged [ OK ]
Broadcast non-IP untagged [ OK ]
Unicast IPv4 untagged [ OK ]

Pull sound fixes from Takashi Iwai:
"Slightly high amount of changes in this round, partly because of my
vacation in the last weeks. But all changes are small and nothing
looks worrisome.
The biggest LOCs is MAINTAINERS updates, and there is a core change
for card-ID string creation for non-ASCII inputs. Others are rather
device-specific, such as new quirks and device IDs for ASoC, usual
HD-audio and USB-audio quirks and fixes, as well as regression fixes
in HD-audio HDMI audio and Conexant codec"

The following patchset contains Netfilter fixes for net:
1) Fix incorrect documentation in uapi/linux/netfilter/nf_tables.h
regarding flowtable hooks, from Phil Sutter.
2) Fix nft_audit.sh selftests with newer nft binaries, due to different
(valid) audit output, also from Phil.
3) Disable BH when duplicating packets via nf_dup infrastructure,
otherwise race on nf_skb_duplicated for locally generated traffic.
From Eric.
4) Missing return in callback of selftest C program, from zhang jiao.

Otherwise, it will be added to kselftest-list.txt. Additionally, add the
