topology_is_core_online() checks if the core a CPU belongs to
is online. The core is online if at least one of the sibling
CPUs is online. The first CPU of an online core is also online
in the common case, so this should be fairly quick.

If a core is offline then enabling SMT should not online CPUs of
this core. By enabling SMT, what is intended is either changing the SMT
value from "off" to "on" or setting the SMT level (threads per core) from a
lower to higher value.
On PowerPC the ppc64_cpu utility can be used, among other things, to
perform the following functions:
ppc64_cpu --cores-on # Get the number of online cores
ppc64_cpu --cores-on=X # Put exactly X cores online
ppc64_cpu --offline-cores=X[,Y,...] # Put specified cores offline
ppc64_cpu --smt={on|off|value} # Enable, disable or change SMT level
If the user has decided to offline certain cores, enabling SMT should
not online CPUs in those cores. This patch fixes the issue and changes
the behaviour as described, by introducing an arch specific function
topology_is_core_online(). It is currently implemented only for PowerPC.

The commit f7866c358733 ("bpf: Fix null pointer dereference in resolve_prog_type() for BPF_PROG_TYPE_EXT")
fixed a NULL pointer dereference panic, but didn't fix the issue that
fails to update attached freplace prog to prog_array map.
Since commit 1c123c567fb1 ("bpf: Resolve fext program type when checking map compatibility"),
freplace prog and its target prog are able to tail call each other.
And the commit 3aac1ead5eb6 ("bpf: Move prog->aux->linked_prog and trampoline into bpf_link on attach")
sets prog->aux->dst_prog as NULL after attaching freplace prog to its
target prog.
After loading freplace the prog_array's owner type is BPF_PROG_TYPE_SCHED_CLS.
Then, after attaching freplace its prog->aux->dst_prog is NULL.
Then, while updating freplace in prog_array the bpf_prog_map_compatible()
incorrectly returns false because resolve_prog_type() returns
BPF_PROG_TYPE_EXT instead of BPF_PROG_TYPE_SCHED_CLS.
After this patch the resolve_prog_type() returns BPF_PROG_TYPE_SCHED_CLS
and update to prog_array can succeed.

Commit fc4444941140 ("scsi: mpi3mr: HDB allocation and posting for hardware
and firmware buffers") added the spinlock trigger_lock to the struct
mpi3mr_ioc. However, spin_lock_init() call was not added for it, then the
lock does not work as expected. Also, the kernel reports the message below
when lockdep is enabled.
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
To fix the issue and to avoid the INFO message, add the missing
spin_lock_init() call.

The NETFS_RREQ_USE_PGPRIV2 and NETFS_RREQ_WRITE_TO_CACHE flags aren't used
correctly. The problem is that we try to set them up in the request
initialisation, but we the cache may be in the process of setting up still,
and so the state may not be correct. Further, we secondarily sample the
cache state and make contradictory decisions later.
The issue arises because we set up the cache resources, which allows the
cache's ->prepare_read() to switch on NETFS_SREQ_COPY_TO_CACHE - which
triggers cache writing even if we didn't set the flags when allocating.
Fix this in the following way:
(1) Drop NETFS_ICTX_USE_PGPRIV2 and instead set NETFS_RREQ_USE_PGPRIV2 in
->init_request() rather than trying to juggle that in
netfs_alloc_request().
(2) Repurpose NETFS_RREQ_USE_PGPRIV2 to merely indicate that if caching is
to be done, then PG_private_2 is to be used rather than only setting
it if we decide to cache and then having netfs_rreq_unlock_folios()
set the non-PG_private_2 writeback-to-cache if it wasn't set.
(3) Split netfs_rreq_unlock_folios() into two functions, one of which
contains the deprecated code for using PG_private_2 to avoid
accidentally doing the writeback path - and always use it if
USE_PGPRIV2 is set.
(4) As NETFS_ICTX_USE_PGPRIV2 is removed, make netfs_write_begin() always
wait for PG_private_2. This function is deprecated and only used by
ceph anyway, and so label it so.
(5) Drop the NETFS_RREQ_WRITE_TO_CACHE flag and use
fscache_operation_valid() on the cache_resources instead. This has
the advantage of picking up the result of netfs_begin_cache_read() and
fscache_begin_write_operation() - which are called after the object is
initialised and will wait for the cache to come to a usable state.
Just reverting ae678317b95e[1] isn't a sufficient fix, so this need to be
applied on top of that. Without this as well, things like:
rcu: INFO: rcu_sched detected expedited stalls on CPUs/tasks: {
and:
WARNING: CPU: 13 PID: 3621 at fs/ceph/caps.c:3386
may happen, along with some UAFs due to PG_private_2 not getting used to
wait on writeback completion.

Commit 6b8e61472529 ("netfs: Rename CONFIG_FSCACHE_DEBUG to
CONFIG_NETFS_DEBUG") renames the config, but introduces two issues: First,
NETFS_DEBUG mistakenly depends on the non-existing config NETFS, whereas
the actual intended config is called NETFS_SUPPORT. Second, the config
renaming misses to adjust the documentation of the functionality of this
config.
Clean up those two points.

After we switch tmpfs dir operations from simple_dir_operations to
simple_offset_dir_operations, every rename happened will fill new dentry
to dest dir's maple tree(&SHMEM_I(inode)->dir_offsets->mt) with a free
key starting with octx->newx_offset, and then set newx_offset equals to
free key + 1. This will lead to infinite readdir combine with rename
happened at the same time, which fail generic/736 in xfstests(detail show
as below).
1. create 5000 files(1 2 3...) under one dir
2. call readdir(man 3 readdir) once, and get one entry
3. rename(entry, "TEMPFILE"), then rename("TEMPFILE", entry)
4. loop 2~3, until readdir return nothing or we loop too many
times(tmpfs break test with the second condition)
We choose the same logic what commit 9b378f6ad48cf ("btrfs: fix infinite
directory reads") to fix it, record the last_index when we open dir, and
do not emit the entry which index >= last_index. The file->private_data
now used in offset dir can use directly to do this, and we also update
the last_index when we llseek the dir file.

This happened because fscache_cookie_state_machine() was slow and was
still running while another process invoked fscache_unuse_cookie();
this led to a fscache_cookie_lru_do_one() call, setting the
FSCACHE_COOKIE_DO_LRU_DISCARD flag, which was picked up by
fscache_cookie_state_machine(), withdrawing the cookie via
cachefiles_withdraw_cookie(), clearing cookie->cache_priv.
At the same time, yet another process invoked
cachefiles_prepare_write(), which found a NULL pointer in this code
line:
struct cachefiles_object *object = cachefiles_cres_object(cres);
The next line crashes, obviously:
struct cachefiles_cache *cache = object->volume->cache;
During cachefiles_prepare_write(), the "n_accesses" counter is
non-zero (via fscache_begin_operation()). The cookie must not be
withdrawn until it drops to zero.
The counter is checked by fscache_cookie_state_machine() before
switching to FSCACHE_COOKIE_STATE_RELINQUISHING and
FSCACHE_COOKIE_STATE_WITHDRAWING (in "case
FSCACHE_COOKIE_STATE_FAILED"), but not for
FSCACHE_COOKIE_STATE_LRU_DISCARDING ("case
FSCACHE_COOKIE_STATE_ACTIVE").
This patch adds the missing check. With a non-zero access counter,
the function returns and the next fscache_end_cookie_access() call
will queue another fscache_cookie_state_machine() call to handle the
still-pending FSCACHE_COOKIE_DO_LRU_DISCARD.

the file_lock slab cache was copied to the new slab cache for

Extent Space Efficient (ESE) or thin provisioned volumes need to be
formatted on demand during usual IO processing.
The dasd_ese_needs_format function checks for error codes that signal
the non existence of a proper track format.
The check for incorrect length is to imprecise since other error cases
leading to transport of insufficient data also have this flag set.
This might lead to data corruption in certain error cases for example
during a storage server warmstart.
Fix by removing the check for incorrect length and replacing by
explicitly checking for invalid track format in transport mode.
Also remove the check for file protected since this is not a valid
ESE handling case.

This reverts commit bc792884b76f ("s390/dasd: Establish DMA alignment").
Quoting the original commit:
linux-next commit bf8d08532bc1 ("iomap: add support for dma aligned
direct-io") changes the alignment requirement to come from the block
device rather than the block size, and the default alignment
requirement is 512-byte boundaries. Since DASD I/O has page
alignments for IDAW/TIDAW requests, let's override this value to
restore the expected behavior.
I mentioned TIDAW, but that was wrong. TIDAWs have no distinct alignment
requirement (per p. 15-70 of POPS SA22-7832-13):
Unless otherwise specified, TIDAWs may designate
a block of main storage on any boundary and length
up to 4K bytes, provided the specified block does not
cross a 4 K-byte boundary.
IDAWs do, but the original commit neglected that while ECKD DASD are
typically formatted in 4096-byte blocks, they don't HAVE to be. Formatting
an ECKD volume with smaller blocks is permitted (dasdfmt -b xxx), and the
problematic commit enforces alignment properties to such a device that
will result in errors, such as:
[test@host ~]# lsdasd -l a367 | grep blksz

mkfs.xfs: pwrite failed: Invalid argument
...snipped...
The original commit omitted the FBA discipline for just this reason,
but the formatted block size of the other disciplines was overlooked.
The solution to all of this is to revert to the original behavior,
such that the block size can be respected. There were two commits [1]
that moved this code in the interim, so a straight git-revert is not
possible, but the change is straightforward.
But what of the original problem? That was manifested with a direct-io
QEMU guest, where QEMU itself was changed a month or two later with
commit 25474d90aa ("block: use the request length for iov alignment")
such that the blamed kernel commit is unnecessary.

This happens because the UAPI provides only seven configuration

Therefore, fix the out-of-bounds read in `v3d_csd_job_run()` by
accessing only seven positions on the '__u32 [7]' array. The eighth
register exists indeed on V3D 7.1, but it isn't currently used. That
being so, let's guarantee that it remains unused and add a note that it
could be set in a future patch.

The MANA driver's RX buffer alloc_size is passed into napi_build_skb() to
create SKB. skb_shinfo(skb) is located at the end of skb, and its alignment
is affected by the alloc_size passed into napi_build_skb(). The size needs
to be aligned properly for better performance and atomic operations.
Otherwise, on ARM64 CPU, for certain MTU settings like 4000, atomic
operations may panic on the skb_shinfo(skb)->dataref due to alignment fault.
To fix this bug, add proper alignment to the alloc_size calculation.

high_memory is set in mem_init() using max_low_pfn, but max_low_pfn
is available long before, it is set in mem_topology_setup(). So just
like commit daa9ada2093e ("powerpc/mm: Fix boot crash with FLATMEM")

====================
net: dsa: vsc73xx: fix MDIO bus access and PHY opera
This series are extracted patches from net-next series [0].
The VSC73xx driver has issues with PHY configuration. This patch series
fixes most of them.
The first patch synchronizes the register configuration routine with the
datasheet recommendations.
Patches 2-3 restore proper communication on the MDIO bus. Currently,
the write value isn't sent to the MDIO register, and without a busy check,
communication with the PHY can be interrupted. This causes the PHY to
receive improper configuration and autonegotiation could fail.
The fourth patch removes the PHY reset blockade, as it is no longer
required.
After fixing the MDIO operations, autonegotiation became possible.
The last patch removes the blockade, which became unnecessary after
the MDIO operations fix.

Resetting the VSC73xx PHY was problematic because the MDIO bus, without
a busy check, read and wrote incorrect register values.
My investigation indicates that resetting the PHY only triggers changes
in configuration. However, improper register values written earlier
were only exposed after a soft reset.
The reset itself wasn't the issue; rather, the problem stemmed from
incorrect read and write operations.
A 'soft_reset' can now proceed normally. There are no reasons to keep
the VSC73xx from being reset.
This commit removes the reset blockade in the 'vsc73xx_phy_write'
function.

The VSC73xx has a busy flag used during MDIO operations. It is raised
when MDIO read/write operations are in progress. Without it, PHYs are
misconfigured and bus operations do not work as expected.

The solution introduced for this product family can derive the required

spi: Add empty versions of ACPI lookup functions
A patch from Richard Fitzgerald adding dummy versions of the ACPI lookup
functions for SPI:
Provide empty versions of acpi_spi_count_resources(),
acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
if the real functions are not being built.
This commit fixes two problems with the original definitions:
1) There wasn't an empty version of these functions
2) The #if only depended on CONFIG_ACPI. But the functions are implemented
in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
functions to exist.

Pull x86 fixes from Thomas Gleixner:
- Fix 32-bit PTI for real.
pti_clone_entry_text() is called twice, once before initcalls so that
initcalls can use the user-mode helper and then again after text is
set read only. Setting read only on 32-bit might break up the PMD
mapping, which makes the second invocation of pti_clone_entry_text()
find the mappings out of sync and failing.
Allow the second call to split the existing PMDs in the user mapping
and synchronize with the kernel mapping.
- Don't make acpi_mp_wake_mailbox read-only after init as the mail box
must be writable in the case that CPU hotplug operations happen after
boot. Otherwise the attempt to start a CPU crashes with a write to
read only memory.
- Add a missing sanity check in mtrr_save_state() to ensure that the
fixed MTRR MSRs are supported.
Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
the WARN_ON() can bring systems down when panic on warn is set.

Pull time keeping fixes from Thomas Gleixner:
- Fix a couple of issues in the NTP code where user supplied values are
neither sanity checked nor clamped to the operating range. This
results in integer overflows and eventualy NTP getting out of sync.
According to the history the sanity checks had been removed in favor
of clamping the values, but the clamping never worked correctly under
all circumstances. The NTP people asked to not bring the sanity
checks back as it might break existing applications.
Make the clamping work correctly and add it where it's missing
- If adjtimex() sets the clock it has to trigger the hrtimer subsystem
so it can adjust and if the clock was set into the future expire
timers if needed. The caller should provide a bitmask to tell
hrtimers which clocks have been adjusted.
adjtimex() uses not the proper constant and uses CLOCK_REALTIME
instead, which is 0. So hrtimers adjusts only the clocks, but does
not check for expired timers, which might make them expire really
late. Use the proper bitmask constant instead.

Fix noise from speakers connected to AUX port when no sound is playing.
The problem occurs because the `alc_shutup_pins` function includes
a 0x10ec0257 vendor ID, which causes noise on Lenovo IdeaPad 3 15IAU7 with
Realtek ALC257 codec when no sound is playing.
Removing this vendor ID from the function fixes the bug.
Fixes: 70794b9563fe ("ALSA: hda/realtek: Add more codec ID to no shutup pins list")
