With GCOV_PROFILE_ALL, Clang injects __llvm_gcov_* functions to each
object file, including the *.mod.o. As we filter out CC_FLAGS_CFI
for *.mod.o, the compiler won't generate type hashes for the
injected functions, and therefore indirectly calling them during
module loading trips indirect call checking.
Enabling CFI for *.mod.o isn't sufficient to fix this issue after
commit 0c3e806ec0f9 ("x86/cfi: Add boot time hash randomization"),
as *.mod.o aren't processed by objtool, which means any hashes
emitted there won't be randomized. Therefore, in addition to
disabling CFI for *.mod.o, also disable GCOV, as the object files
don't otherwise contain any executable code.

With GCOV_PROFILE_ALL, Clang injects __llvm_gcov_* functions to
each object file, and the functions are indirectly called during
boot. However, when code is injected to object files that are not
part of vmlinux.o, it's also not processed by objtool, which breaks
CFI hash randomization as the hashes in these files won't be
included in the .cfi_sites section and thus won't be randomized.
Similarly to commit 42633ed852de ("kbuild: Fix CFI hash
randomization with KASAN"), disable GCOV for .vmlinux.export.o and
init/version-timestamp.o to avoid emitting unnecessary functions to
object files that don't otherwise have executable code.

Commit cd968b97c492 ("kbuild: make built-in.a rule robust against too
long argument error") made a build rule robust against "Argument list
too long" error.
Eugeniu Rosca reported the same error occurred when cleaning an external
module.
The $(obj)/ prefix can be a very long path for external modules.
Apply a similar solution to 'make clean'.

Request allocated from sched tags can't be issued via ->queue_rqs()
directly, since driver tag isn't allocated yet. This is the 1st misuse
of RQF_USE_SCHED for figuring out plug->has_elevator.
Request allocated from sched tags can't be ended by
blk_mq_end_request_batch() too, fix the 2nd RQF_USE_SCHED misuse
in blk_mq_add_to_batch().
Without this patch, NVMe uring cmd passthrough IO workload can run into

After commit f382fb0bcef4 ("block: remove legacy IO schedulers"),
blkio.throttle.io_serviced and blkio.throttle.io_service_bytes become
the only stable io stats interface of cgroup v1, and these statistics
are done in the blk-throttle code. But the current code only counts the
bios that are actually throttled. When the user does not add the throttle
limit, the io stats for cgroup v1 has nothing. I fix it according to the
statistical method of v2, and made it count all ios accurately.

According to CTA 861 the channel/speaker allocation info in the
audio infoframe only applies to uncompressed (PCM) audio streams.
The channel count info should indicate the number of channels
in the transmitted audio, which usually won't match the number of
channels used to transmit the compressed bitstream.
Some devices (eg some Sony TVs) will refuse to decode compressed
audio if these values are not set correctly.
To fix this we can simply set the channel count to 0 (which means
"refer to stream header") and set the channel/speaker allocation to 0
as well (which would mean stereo FL/FR for PCM, a safe value all sinks
will support) when transmitting compressed audio.

The SADs of compressed formats contain the channel and sample rate
info of the audio data inside the compressed stream, but when
building constraints we must use the rates and channels used to
transport the compressed streams.
eg 48kHz 6ch EAC3 needs to be transmitted as a 2ch 192kHz stream.
This patch fixes the constraints for the common AC3 and DTS formats,
the constraints for the less common MPEG, DSD etc formats are copied
directly from the info in the SADs as before as I don't have the specs
and equipment to test those.

David Howells says:
====================
splice, net: Switch over users of sendpage() and remove it
Here's the final set of patches towards the removal of sendpage. All the
drivers that use sendpage() get switched over to using sendmsg() with
MSG_SPLICE_PAGES.
The following changes are made:
(1) Make the protocol drivers behave according to MSG_MORE, not
MSG_SENDPAGE_NOTLAST. The latter is restricted to turning on MSG_MORE
in the sendpage() wrappers.
(2) Fix ocfs2 to allocate its global protocol buffers with folio_alloc()
rather than kzalloc() so as not to invoke the !sendpage_ok warning in
skb_splice_from_iter().
(3) Make ceph/rds, skb_send_sock, dlm, nvme, smc, ocfs2, drbd and iscsi
use sendmsg(), not sendpage and make them specify MSG_MORE instead of
MSG_SENDPAGE_NOTLAST.
(4) Kill off sendpage and clean up MSG_SENDPAGE_NOTLAST.

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned
up. Things were converted to use MSG_MORE instead, but the protocol
sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now
unnecessary.

ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
o2net_keep_resp and then passes these to sendpage. This isn't really
allowed as the lifetime of slab objects is not controlled by page ref -
though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
will, however, print a warning and give an error.
Fix it to use folio_alloc() instead to allocate a buffer for the handshake
message, keepalive request and reply messages.

64-bit DMA detection will fail if axienet was started before (by boot
loader, boot ROM, etc). In this state axienet will not start properly.
XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
is used to fetch the first descriptor. So iowrite32()/ioread32() trick
to this register to detect 64-bit DMA will not work.
So move axienet reset before 64-bit DMA detection.

run_tests() accepts too many optional parameters. Before this modification,
it was required to set all of then when only the last one had to be
changed. That's not clear to see all these 0 and it makes the maintenance
harder:
run_tests $ns1 $ns2 10.0.1.1 1 2 3 slow
Instead, the parameter can be set as an env var with a limited scope:
foo=1 bar=2 next=3 \
run_tests $ns1 $ns2 10.0.1.1 slow
This patch switches to key/value "sflags=*" instead of positional parameter
sflags of do_transfer() and run_tests().

New MPTCP info are being checked in multiple places to improve the code
coverage when using the userspace PM.
This patch makes chk_mptcp_info() more generic to be able to check
subflows, add_addr_signal and add_addr_accepted info (and even more
later). New arguments are now required to get different infos from the
two namespaces because some counters are specific to the client or the
server.

Bartosz Golaszewski says:
====================
net: stmmac: introduce devres helpers for stmmac platform drivers
The goal of this series is two-fold: to make the API for stmmac platforms more
logically correct (by providing functions that acquire resources with release
counterparts that undo only their actions and nothing more) and to provide
devres variants of commonly use registration functions that allows to
significantly simplify the platform drivers.
The current pattern for stmmac platform drivers is to call
stmmac_probe_config_dt(), possibly the platform's init() callback and then
call stmmac_drv_probe(). The resources allocated by these calls will then
be released by calling stmmac_pltfr_remove(). This goes against the commonly
accepted way of providing each function that allocated a resource with a
function that frees it.
First: provide wrappers around platform's init() and exit() callbacks that
allow users to skip checking if the callbacks exist manually.
Second: provide stmmac_pltfr_probe() which calls the platform init() callback
and then calls stmmac_drv_probe() together with a variant of
stmmac_pltfr_remove() that DOES NOT call stmmac_remove_config_dt(). For now
this variant is called stmmac_pltfr_remove_no_dt() but once all users of
the old stmmac_pltfr_remove() are converted to the devres helper, it will be
renamed back to stmmac_pltfr_remove() and the no_dt function removed.
Finally use the devres helpers in dwmac-qco-ethqos to show how much simplier
the driver's probe() becomes.
This series obviously just starts the conversion process and other platform
drivers will need to be converted once the helpers land in net/.
