SCLK_SDMMC is the parent for SCLK_SDMMC_DRV and SCLK_SDMMC_SAMPLE, but
used with the (more) correct name sclk_sdmmc. SD card tuning does currently
fail as the parent can't be found under that name.
There is no need to suffix the name with '0' since RK312x SoCs do have a
single sdmmc controller - so rename it to the name which is already used
by it's children.

According to the TRM there are no specific gpll_peri, cpll_peri,
gpll_div2_peri or gpll_div3_peri gates, but a single clk_peri_src gate.
Instead mux_clk_peri_src directly connects to the plls respectively the pll
divider clocks.
Fix this by creating a single gated composite.
Also rename all occurrences of aclk_peri_src to clk_peri_src, since it
is the parent for peri aclks, pclks and hclks. That name also matches

[ Upstream commit e645c20e8e9cde549bc233435d3c1338e1cd27fe ]
The enforce_cache_coherency callback ensures DMA cache coherency for
devices attached to the domain.
Intel IOMMU supports enforced DMA cache coherency when the Snoop
Control bit in the IOMMU's extended capability register is set.
Supporting it differs between legacy and scalable modes.
In legacy mode, it's supported page-level by setting the SNP field
in second-stage page-table entries. In scalable mode, it's supported
in PASID-table granularity by setting the PGSNP field in PASID-table
entries.
In legacy mode, mappings before attaching to a device have SNP
fields cleared, while mappings after the callback have them set.
This means partial DMAs are cache coherent while others are not.
One possible fix is replaying mappings and flipping SNP bits when
attaching a domain to a device. But this seems to be over-engineered,
given that all real use cases just attach an empty domain to a device.
To meet practical needs while reducing mode differences, only support
enforce_cache_coherency on a domain without mappings if SNP field is
used.

[ Upstream commit 80aea01c48971a1fffc0252d036995572d84950d ]
When the host invalidates a guest page, it will also check if the page
was used to map the prefix of any guest CPUs, in which case they are
stopped and marked as needing a prefix refresh. Upon starting the
affected CPUs again, their prefix pages are explicitly faulted in and
revalidated if they had been invalidated. A bit in the PGSTEs indicates
whether or not a page might contain a prefix. The bit is allowed to
overindicate. Pages above 2G are skipped, because they cannot be
prefixes, since KVM runs all guests with MSO = 0.
The same applies for nested guests (VSIE). When the host invalidates a
guest page that maps the prefix of the nested guest, it has to stop the
affected nested guest CPUs and mark them as needing a prefix refresh.
The same PGSTE bit used for the guest prefix is also used for the
nested guest. Pages above 2G are skipped like for normal guests, which
is the source of the bug.
The nested guest runs is the guest primary address space. The guest
could be running the nested guest using MSO != 0. If the MSO + prefix
for the nested guest is above 2G, the check for nested prefix will skip
it. This will cause the invalidation notifier to not stop the CPUs of
the nested guest and not mark them as needing refresh. When the nested
guest is run again, its prefix will not be refreshed, since it has not
been marked for refresh. This will cause a fatal validity intercept
with VIR code 37.
Fix this by removing the check for 2G for nested guests. Now all
invalidations of pages with the notify bit set will always scan the
existing VSIE shadow state descriptors.
This allows to catch invalidations of nested guest prefix mappings even
when the prefix is above 2G in the guest virtual address space.

[ Upstream commit 9715ed501b585d47444865071674c961c0cc0020 ]
The commit:
cff9b2332ab7 ("kernel/sched: Modify initial boot task idle setup")
has changed the semantics of what is to be considered an idle task in
such a way that CPU boot code preceding the actual idle loop is excluded
from it.
This has however introduced new potential RCU-tasks stalls when either:
1) Grace period is started before init/0 had a chance to set PF_IDLE,
keeping it stuck in the holdout list until idle ever schedules.
2) Grace period is started when some possible CPUs have never been
online, keeping their idle tasks stuck in the holdout list until the
CPU ever boots up.
3) Similar to 1) but with secondary CPUs: Grace period is started
concurrently with secondary CPU booting, putting its idle task in
the holdout list because PF_IDLE isn't yet observed on it. It stays
then stuck in the holdout list until that CPU ever schedules. The
effect is mitigated here by the hotplug AP thread that must run to
bring the CPU up.
Fix this with handling the new semantics of PF_IDLE, keeping in mind
that it may or may not be set on an idle task. Take advantage of that to
strengthen the coverage of an RCU-tasks quiescent state within an idle
task, excluding the CPU boot code from it. Only the code running within
the idle loop is now a quiescent state, along with offline CPUs.

It turns out that even kfree_rcu() isn't safe for avoiding

the following circular locking dependency now exists:

The mtty driver does not currently conform to the vfio SET_IRQS uAPI.
For example, it claims to support mask and unmask of INTx, but actually
does nothing. It claims to support AUTOMASK for INTx, but doesn't. It
fails to teardown eventfds under the full semantics specified by the
SET_IRQS ioctl. It also fails to teardown eventfds when the device is
closed, leading to memory leaks. It claims to support the request IRQ,
but doesn't.
Fix all these.
A side effect of this is that QEMU will now report a warning:
vfio <uuid>: Failed to set up UNMASK eventfd signaling for interrupt \
INTX-0: VFIO_DEVICE_SET_IRQS failure: Inappropriate ioctl for device
The fact is that the unmask eventfd was never supported but quietly
failed. mtty never honored the AUTOMASK behavior, therefore there
was nothing to unmask. QEMU is verbose about the failure, but
properly falls back to userspace unmasking.

Since commit adad556efcdd ("crypto: api - Fix built-in testing
dependency failures"), the following warning appears when booting an
x86_64 kernel that is configured with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y and CONFIG_CRYPTO_AES_NI_INTEL=y,
even when CONFIG_CRYPTO_XTS=y and CONFIG_CRYPTO_AES=y:
alg: skcipher: skipping comparison tests for xts-aes-aesni because xts(ecb(aes-generic)) is unavailable
This is caused by an issue in the xts template where it allocates an
"aes" single-block cipher without declaring a dependency on it via the
crypto_spawn mechanism. This issue was exposed by the above commit
because it reversed the order that the algorithms are tested in.
Specifically, when "xts(ecb(aes-generic))" is instantiated and tested
during the comparison tests for "xts-aes-aesni", the "xts" template
allocates an "aes" crypto_cipher for encrypting tweaks. This resolves
to "aes-aesni". (Getting "aes-aesni" instead of "aes-generic" here is a
bit weird, but it's apparently intended.) Due to the above-mentioned
commit, the testing of "aes-aesni", and the finalization of its
registration, now happens at this point instead of before. At the end
of that, crypto_remove_spawns() unregisters all algorithm instances that
depend on a lower-priority "aes" implementation such as "aes-generic"
but that do not depend on "aes-aesni". However, because "xts" does not
use the crypto_spawn mechanism for its "aes", its dependency on
"aes-aesni" is not recognized by crypto_remove_spawns(). Thus,
crypto_remove_spawns() unexpectedly unregisters "xts(ecb(aes-generic))".
Fix this issue by making the "xts" template use the crypto_spawn
mechanism for its "aes" dependency, like what other templates do.
Note, this fix could be applied as far back as commit f1c131b45410
("crypto: xts - Convert to skcipher"). However, the issue only got
exposed by the much more recent changes to how the crypto API runs the
self-tests, so there should be no need to backport this to very old
kernels. Also, an alternative fix would be to flip the list iteration
order in crypto_start_tests() to restore the original testing order.
I'm thinking we should do that too, since the original order seems more
natural, but it shouldn't be relied on for correctness.

libbpf accesses the ELF data requiring at least 8 byte alignment,
however, the data is generated into a C string that doesn't guarantee
alignment. Fix this by assigning to an aligned char array. Use sizeof
on the array, less one for the \0 terminator, rather than generating a
constant.

to eliminate a warning (as i understand

While BPF allows to set icsk->->icsk_delack_max
and/or icsk->icsk_rto_min, we have an ip route
attribute (RTAX_RTO_MIN) to be able to tune rto_min,
but nothing to consequently adjust max delayed ack,
which vary from 40ms to 200 ms (TCP_DELACK_{MIN|MAX}).
This makes RTAX_RTO_MIN of almost no practical use,
unless customers are in big trouble.
Modern days datacenter communications want to set
rto_min to ~5 ms, and the max delayed ack one jiffie
smaller to avoid spurious retransmits.
After this patch, an "rto_min 5" route attribute will
effectively lower max delayed ack timers to 4 ms.

Patch series "Three memory-failure fixes".
I've been looking at the memory-failure code and I believe I have found
three bugs that need fixing -- one going all the way back to 2010! I'll
have more patches later to use folios more extensively but didn't want
these bugfixes to get caught up in that.
This patch (of 3):
Both collect_procs_anon() and collect_procs_file() iterate over the VMA
interval trees looking for a single pgoff, so it is wrong to look for the
pgoff of the head page as is currently done. However, it is also wrong to
look at page->mapping of the precise page as this is invalid for tail
pages. Clear up the confusion by passing both the folio and the precise
page to collect_procs().

Prevent move_mount from applying the attach_disconnected flag
to move_mount(). This prevents detached mounts from appearing
as / when applying mount mediation, which is not only incorrect
but could result in bad policy being generated.
Basic mount rules like
allow mount,
allow mount options=(move) -> /target/,
will allow detached mounts, allowing older policy to continue
to function. New policy gains the ability to specify `detached` as
a source option
allow mount detached -> /target/,
In addition make sure support of move_mount is advertised as
a feature to userspace so that applications that generate policy
can respond to the addition.
Note: this fixes mediation of move_mount when a detached mount is used,
it does not fix the broader regression of apparmor mediation of
mounts under the new mount api.

we get events generated to userspace notifying applications of the change.
While the I2S mux gets this right the S/PDIF mux does not, fix the return
value.

We are checking if there has been a change and exiting early if not but we
are not providing the correct return value in the latter case, fix this.

When writing to an enum we need to verify that the value written is valid
for the enumeration, the helper function snd_soc_item_enum_to_val() doesn't
do it since it needs to return an unsigned (and in any case we'd need to
check the return value).
