A small number of fixes for zstd-v1.5.2.
I'm not pulling in zstd-v1.5.4 from upstream this release because it
didn't have any time to bake in linux-next, but I'm aiming for the next
update in v6.4.
I've rebased my tree onto v6.2 to remove the incorrect back merges as
suggested by Linus in my initial PR for v6.3 [0].

A while ago where the trace events had the following:
rcu_read_lock_sched_notrace();
rcu_dereference_sched(...);
rcu_read_unlock_sched_notrace();
If the tracepoint is enabled, it could trigger RCU issues if called in
the wrong place. And this warning was only triggered if lockdep was
enabled. If the tracepoint was never enabled with lockdep, the bug would
not be caught. To handle this, the above sequence was done when lockdep
was enabled regardless if the tracepoint was enabled or not (although the
always enabled code really didn't do anything, it would still trigger a
warning).
But a lot has changed since that lockdep code was added. One is, that
sequence no longer triggers any warning. Another is, the tracepoint when
enabled doesn't even do that sequence anymore.
The main check we care about today is whether RCU is "watching" or not.
So if lockdep is enabled, always check if rcu_is_watching() which will
trigger a warning if it is not (tracepoints require RCU to be watching).
Note, that old sequence did add a bit of overhead when lockdep was enabled,
and with the latest kernel updates, would cause the system to slow down
enough to trigger kernel "stalled" warnings.

Starting from an used_idx different than 0 is needed in use cases like
virtual machine migration. Not doing so and letting the caller set an
avail idx different than 0 causes destination device to try to use old
buffers that source driver already recover and are not available
anymore.
Since vdpa_sim does not support receive inflight descriptors as a
destination of a migration, let's set both avail_idx and used_idx the
same at vq start. This is how vhost-user works in a
VHOST_SET_VRING_BASE call.
Although the simple fix is to set last_used_idx at vdpasim_set_vq_state,
it would be reset at vdpasim_queue_ready. The last_avail_idx case is
fixed with commit 0e84f918fa ("vdpa_sim: not reset state in
vdpasim_queue_ready"). Since the only option is to make it equal to
last_avail_idx, adding the only change needed here.
This was discovered and tested live migrating the vdpa_sim_net device.

Currently vhost_vdpa_cleanup() unmaps the DMA mappings by calling
`iommu_unmap(v->domain, map->start, map->size);`
from vhost_vdpa_general_unmap() when the parent vDPA driver doesn't
provide DMA config operations.
However, the IOMMU domain referred to by `v->domain` is freed in
vhost_vdpa_free_domain() before vhost_vdpa_cleanup() in
vhost_vdpa_release() which results in NULL pointer de-reference.
Accordingly, moving the call to vhost_vdpa_free_domain() in
vhost_vdpa_cleanup() would makes sense. This will also help
detaching the dma device in error handling of vhost_vdpa_alloc_domain().
This issue was observed on terminating QEMU with SIGQUIT.

"Two additional bug fixes for v6.3"
* tag 'tpm-v6.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd:
tpm: disable hwrng for fTPM on some AMD designs
tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address
AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d5 ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

Here are 4 small staging driver fixes, and one big staging driver
deletion for 6.3-rc2.
The fixes are:
- rtl8192e driver fixes for where the driver was attempting to execute
various programs directly from the disk for unknown reasons
- rtl8723bs driver fixes for issues found by Hans in testing
The deleted driver is the removal of the r8188eu wireless driver as now
in 6.3-rc1 we have a "real" wifi driver for one that includes support
for many many more devices than this old driver did. So it's time to
remove it as it is no longer needed. The maintainers of this driver all
have acked its removal. Many thanks to them over the years for working
to clean it up and keep it working while the real driver was being
developed.
All of these have been in linux-next this week with no reported
problems.

Pull staging driver fixes and removal from Greg KH:
"Here are four small staging driver fixes, and one big staging driver
deletion for 6.3-rc2.
The fixes are:
- rtl8192e driver fixes for where the driver was attempting to
execute various programs directly from the disk for unknown reasons
- rtl8723bs driver fixes for issues found by Hans in testing
The deleted driver is the removal of the r8188eu wireless driver as
now in 6.3-rc1 we have a "real" wifi driver for one that includes
support for many many more devices than this old driver did. So it's
time to remove it as it is no longer needed. The maintainers of this
driver all have acked its removal. Many thanks to them over the years
for working to clean it up and keep it working while the real driver
was being developed.
All of these have been in linux-next this week with no reported
problems"

The CLONE_NEWTIME allows the creation of time namespaces. The flag

system call to set the signal that gets sent to the parent after the
child exits.
The clone3() system call doesn't rely on CSIGNAL anymore as it uses a
dedicated .exit_signal field in struct clone_args. So we blocked all
CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced
and reused a CSIGNAL bit we forgot to adapt clone3_args_valid()

The cpumask_check() was unnecessarily tight, and causes problems for the
users of cpumask_next().
We have a number of users that take the previous return value of one of
the bit scanning functions and subtract one to keep it in "range". But
since the scanning functions end up returning up to 'small_cpumask_bits'
instead of the tighter 'nr_cpumask_bits', the range really needs to be
using that widened form.
[ This "previous-1" behavior is also the reason we have all those
comments about /* -1 is a legal arg here. */ and separate checks for
that being ok. So we could have just made "small_cpumask_bits-1"
be a similar special "don't check this" value.
Tetsuo Handa even suggested a patch that only does that for
cpumask_next(), since that seems to be the only actual case that
triggers, but that all makes it even _more_ magical and special. So
just relax the check ]
One example of this kind of pattern being the 'c_start()' function in
arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on
other architectures.

If the boot loader inode has never been used before, the
EXT4_IOC_SWAP_BOOT inode will initialize it, including setting the

Merge tag 'io_uring-6.3-2023-03-09' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- Stop setting PF_NO_SETAFFINITY on io-wq workers.
This has been reported in the past as it confuses some applications,
as some of their threads will fail with -1/EINVAL if attempted
affinitized. Most recent report was on cpusets, where enabling that
with io-wq workers active will fail.
Just deal with the mask changing by checking when a worker times out,
and then exit if we have no work pending.
- Fix an issue with passthrough support where we don't properly check
if the file type has pollable uring_cmd support.
- Fix a reported W=1 warning on a variable being set and unused. Add a
special helper for iterating these lists that doesn't save the
previous list element, if that iterator never ends up using it.

copy from upstream so that a merge is avoided and the end result after merging
this pull request is the one expected, tools/perf/check-headers.sh (mostly)
happy, less warnings while building tools/perf/.
- Fix counting when initial delay configured by setting
perf_attr.enable_on_exec when starting workloads from the perf command line.
- Don't avoid emitting a PERF_RECORD_MMAP2 in 'perf inject --buildid-all' when
that record comes with a build-id, otherwise we end up not being able to
resolve symbols.
- Don't use comma as the CSV output separator the "stat+csv_output" test, as
comma can appear on some tests as a modifier for an event, use @ instead,
ditto for the JSON linter test.
- The offcpu test was looking for some bits being set on
task_struct->prev_state without masking other bits not important for this
specific 'perf test', fix it.

Before the first pg->index++, index is 0 and accessing pg->records[-1].ip
