Drop libbpf, libelf, libz dependency from bpf preload.
This reduces bpf_preload_umd binary size
from 1.7M to 30k unstripped with debug info
and from 300k to 19k stripped.

Since we've started treating fallocate more like a file write, we
should flush the log to disk if the user has asked for synchronous
writes either by setting it via fcntl flags, or inode flags, or with
the sync mount option. We've already got a helper for this, so use
it.

The operations that xfs_update_prealloc_flags() perform are now
unique to xfs_fs_map_blocks(), so move xfs_update_prealloc_flags()
to be a static function in xfs_pnfs.c and cut out all the
other functionality that is doesn't use anymore.

Now that we only call xfs_update_prealloc_flags() from
xfs_file_fallocate() in the case where we need to set the
preallocation flag, do this in xfs_alloc_file_space() where we
already have the inode joined into a transaction and get
rid of the call to xfs_update_prealloc_flags() from the fallocate
code.
This also means that we now correctly avoid setting the
XFS_DIFLAG_PREALLOC flag when xfs_is_always_cow_inode() is true, as
these inodes will never have preallocated extents.

In XFS, we always update the inode change and modification time when
any fallocate() operation succeeds. Furthermore, as various
fallocate modes can change the file contents (extending EOF,
punching holes, zeroing things, shifting extents), we should drop
file privileges like suid just like we do for a regular write().
There's already a VFS helper that figures all this out for us, so
use that.
The net effect of this is that we no longer drop suid/sgid if the
caller is root, but we also now drop file capabilities.
We also move the xfs_update_prealloc_flags() function so that it now
is only called by the scope that needs to set the the prealloc flag.
Based on a patch from Darrick Wong.

When cross-building tools with clang, we run `which $(CROSS_COMPILE)gcc`
to detect whether a GCC toolchain provides the standard libraries. It is
only a helper because some distros put libraries where LLVM does not
automatically find them. On other systems, LLVM detects the libc
automatically and does not need this. There, it is completely fine not
to have a GCC at all, but some versions of `which' display an error when
the command is not found:
which: no aarch64-linux-gnu-gcc in ($PATH)
Since the error can safely be ignored, throw it to /dev/null.

In kvm_arch_vcpu_ioctl_run() we enter an RCU extended quiescent state
(EQS) by calling guest_enter_irqoff(), and unmasked IRQs prior to
exiting the EQS by calling guest_exit(). As the IRQ entry code will not
wake RCU in this case, we may run the core IRQ code and IRQ handler
without RCU watching, leading to various potential problems.
Additionally, we do not inform lockdep or tracing that interrupts will
be enabled during guest execution, which caan lead to misleading traces
and warnings that interrupts have been enabled for overly-long periods.
This patch fixes these issues by using the new timing and context
entry/exit helpers to ensure that interrupts are handled during guest
vtime but with RCU watching, with a sequence:
guest_timing_enter_irqoff();
guest_state_enter_irqoff();
< run the vcpu >
guest_state_exit_irqoff();
< take any pending IRQs >
guest_timing_exit_irqoff();
Since instrumentation may make use of RCU, we must also ensure that no
instrumented code is run during the EQS. I've split out the critical
section into a new kvm_arm_enter_exit_vcpu() helper which is marked
noinstr.

Christian reported a NULL pointer dereference in j721e_pcie_probe() caused
by 19e863828acf ("PCI: j721e: Drop redundant struct device *"), which
removed struct j721e_pcie.dev since there's another copy in struct
cdns_pcie.dev reachable via j721e_pcie->cdns_pcie->dev.
The problem is that j721e_pcie->cdns_pcie was dereferenced before being
initialized:
j721e_pcie_probe
pcie = devm_kzalloc() # struct j721e_pcie
j721e_pcie_ctrl_init(pcie)
dev = pcie->cdns_pcie->dev <-- dereference cdns_pcie
switch (mode) {
case PCI_MODE_RC:
cdns_pcie = ... # alloc as part of pci_host_bridge
pcie->cdns_pcie = cdns_pcie <-- initialize pcie->cdns_pcie
Move the cdns_pcie initialization earlier so it is done before it is used.
This also simplifies the error exits.

Move cifs to using fscache DIO API instead of the old upstream I/O API as
that has been removed. This is a stopgap solution as the intention is that
at sometime in the future, the cache will move to using larger blocks and
won't be able to store individual pages in order to deal with the potential
for data corruption due to the backing filesystem being able insert/remove
bridging blocks of zeros into its extent list[1].
cifs then reads and writes cache pages synchronously and one page at a time.
The preferred change would be to use the netfs lib, but the new I/O API can
be used directly. It's just that as the cache now needs to track data for
itself, caching blocks may exceed page size...
This code is somewhat borrowed from my "fallback I/O" patchset[2].

To pick the changes in:

This new PR_SET_VMA value isn't in sequence with all the other prctl
arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A).
This makes it harder to generate a string table as it would be rather
sparse, so make the regexp more stricter to avoid catching those.
A followup patch for 'perf trace' to cope with such oddities will be
needed, but then its a matter for the next merge window.
The next patch will update the prctl.h file to cope with this perf build

ASoC: Fixes for v5.17
Quite a few fixes here, including an unusually large set in the core
spurred on by various testing efforts as well as the usual small driver
fixes. There are quite a few fixes for out of bounds writes in both the
core and the various Qualcomm drivers, plus a couple of fixes for
locking in the DPCM code.

platforms
Lenovo AMD based platforms have been offering platform_profiles but they
are not working correctly. This is because the mode we are using on the
Intel platforms (MMC) is not available on the AMD platforms.
This commit adds checking of the functional capabilities returned by the
BIOS to confirm if MMC is supported or not. Profiles will not be
available if the platform is not MMC capable.
I'm investigating and working on an alternative for AMD platforms but
that is still work-in-progress.

====================
net: lan966x: Add PTP Hardward Clock support
Add support for PTP Hardware Clock (PHC) for lan966x. The switch supports
both PTP 1-step and 2-step modes.
v1->v2:
- fix commit messages
- reduce the scope of the lock ptp_lock inside the function
lan966x_ptp_hwtstamp_set
- the rx timestamping is always enabled for all packages

Implement the function get_ts_info in ethtool_ops which is needed to get
the HW capabilities for timestamping.

When doing 2-step timestamping the HW will generate an interrupt when it
managed to timestamp a frame. It is the SW responsibility to read it
from the FIFO.

Update both the extraction and injection to do timestamping of the
frames. The extraction is always doing the timestamping while for
injection is doing the timestamping only if it is configured.

Implement the ioctl callbacks SIOCSHWTSTAMP and SIOCGHWTSTAMP to allow
to configure the ports to enable/disable timestamping for TX. The RX
timestamping is always enabled. The HW is capable to run both 1-step
timestamping and 2-step timestamping.

If the codec->registered is not set then it means that pm_runtime is
not yet enabled and the codec->pcm_list_head has not been initialized.
The access to the not initialized pcm_list_head will lead a kernel crash
during shutdown.
