A new fscache-based shared domain mode is going to be introduced for
erofs. In which case, same data blobs in same domain will be shared
and reused to reduce on-disk space usage.
The implementation of sharing blobs will be introduced in subsequent
patches.

The AMD IOMMU driver cannot activate PASID mode on a RID without the RID's
translation being set to IDENTITY. Further it requires changing the RID's
page table layout from the normal v1 IOMMU_DOMAIN_IDENTITY layout to a
different v2 layout.
It does this by creating a new iommu_domain, configuring that domain for
v2 identity operation and then attaching it to the group, from within the
driver. This logic assumes the group is already set to the IDENTITY domain
and is being used by the DMA API.
However, since the ownership logic is based on the group's domain pointer
equaling the default domain to detect DMA API ownership, this causes it to
look like the group is not attached to the DMA API any more. This blocks
attaching drivers to any other devices in the group.
In a real system this manifests itself as the HD-audio devices on some AMD
platforms losing their device drivers.
Work around this unique behavior of the AMD driver by checking for
equality of IDENTITY domains based on their type, not their pointer
value. This allows the AMD driver to have two IDENTITY domains for
internal purposes without breaking the check.
Have the AMD driver properly declare that the special domain it created is
actually an IDENTITY domain.

The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac
("iommu/vt-d: Introduce a rwsem to protect global data structures"). It
is used to protect DMAR related global data from DMAR hotplug operations.
The dmar_global_lock used in the intel_iommu_init() might cause recursive
locking issue, for example, intel_iommu_get_resv_regions() is taking the
dmar_global_lock from within a section where intel_iommu_init() already
holds it via probe_acpi_namespace_devices().
Using dmar_global_lock in intel_iommu_init() could be relaxed since it is
unlikely that any IO board must be hot added before the IOMMU subsystem is
initialized. This eliminates the possible recursive locking issue by moving
down DMAR hotplug support after the IOMMU is initialized and removing the
uses of dmar_global_lock in intel_iommu_init().

Here are some small driver core and debugfs fixes for 6.0-rc5.
Included in here are:
- multiple attempts to get the arch_topology code to work properly on
non-cluster SMT systems. First attempt caused build breakages in
linux-next and 0-day, second try worked.
- debugfs fixes for a long-suffering memory leak. The pattern of
debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
add debugfs_lookup_and_remove() to fix this problem. Also fix up

Pull driver core fixes from Greg KH:
"Here are some small driver core and debugfs fixes for 6.0-rc5.
Included in here are:
- multiple attempts to get the arch_topology code to work properly on
non-cluster SMT systems. First attempt caused build breakages in
linux-next and 0-day, second try worked.
- debugfs fixes for a long-suffering memory leak. The pattern of
debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
add debugfs_lookup_and_remove() to fix this problem. Also fix up
the scheduler debug code that highlighted this problem. Fixes for

Commit c461731836 ("MIPS: Add NUMA support for Loongson-3") has increased
.bss size of the Octeon kernel from 16k to 16M. Providing the conditions
for SPARSEMEM_EXTREME avoids the waste of memory.
Thomas has tested the loogsoon64 kernel, where .bss is being reduced by
this patch from 16.5M to 515k.

We have a couple of problems, first reports of unexpected link breakage
for reads when cqe->res indicates that the IO was done in full. The
reason here is partial IO with retries.
TL;DR; we compare the result in __io_complete_rw_common() against
req->cqe.res, but req->cqe.res doesn't store the full length but rather
the length left to be done. So, when we pass the full corrected result
via kiocb_done() -> __io_complete_rw_common(), it fails.
The second problem is that we don't try to correct res in
io_complete_rw(), which, for instance, might be a problem for O_DIRECT
but when a prefix of data was cached in the page cache. We also
definitely don't want to pass a corrected result into io_rw_done().
The fix here is to leave __io_complete_rw_common() alone, always pass
not corrected result into it and fix it up as the last step just before
actually finishing the I/O.

- fix zone append limit in emulated mode

- fix regression, user settable data chunk limit got accidentally

we received lots of small fixes for various drivers at this time,
hopefully it will be the last big bump before 6.0 release.
The significant changes are regression fixes for (yet again) HD-audio
memory allocations and USB-audio PCM parameter handling, while there
are many small ASoC device-specific fixes as well as a few
out-of-bounds and race issues spotted by fuzzers.

SBI firmware should report total number of firmware and hardware counters
including unused ones or special ones. In this case the kernel doesn't need
to make any assumptions about gaps in reported counters, e.g. excluded timer
counter. That was fixed in OpenSBI v1.1 by commit 3f66465fb6bf ("lib: pmu:
allow to use the highest available counter"). This kernel patch has no effect
if SBI firmware behaves correctly. However it eliminates access beyond the
allocated pmu_ctr_list if the kernel is used with OpenSBI older than v1.1.

Some calls to synthesis functions set err < 0 but only warn about the
failure and continue. However they do not set err back to zero, relying
on subsequent code to do that.
That changed with the introduction of option --synth. When --synth=no
subsequent functions that set err back to zero are not called.
Fix by setting err = 0 in those cases.
Example:
Before:
$ perf record --no-bpf-event --synth=all -o /tmp/huh uname
Couldn't synthesize bpf events.
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.014 MB /tmp/huh (7 samples) ]
$ perf record --no-bpf-event --synth=no -o /tmp/huh uname
Couldn't synthesize bpf events.
After:
$ perf record --no-bpf-event --synth=no -o /tmp/huh uname
Couldn't synthesize bpf events.

According to Moortec Embedded Voltage Monitor (MEVM) series 3 data
sheet, the minimum input signal is -100mv and maximum input signal
is +1000mv.
The equation used to convert the digital word to voltage uses mixed
types (*val signed and n unsigned), and on 64 bit machines also has
different size, since sizeof(u32) = 4 and sizeof(long) = 8.
So when measuring a negative input, n will be small enough, such that
PVT_N_CONST * n < PVT_R_CONST, and the result of
(PVT_N_CONST * n - PVT_R_CONST) will overflow to a very big positive
32 bit number. Then when storing the result in *val it will be the same
value just in 64 bit (instead of it representing a negative number which
will what happen when sizeof(long) = 4).
When -1023 <= (PVT_N_CONST * n - PVT_R_CONST) <= -1
dividing the number by 1024 should result of in 0, but because ">> 10"
is used, and the sign bit is used to fill the vacated bit positions, it
results in -1 (0xf...fffff) which is wrong.
This change fixes the sign problem and supports negative values by
casting n to long and replacing the shift right with div operation.

Bug - in case "intel,vm-map" is missing in device-tree ,'num' is set
to 0, and no voltage channel infos are allocated.
The reason num is set to 0 when "intel,vm-map" is missing is to set the
entire pvt->vm_idx[] with incremental channel numbers, but it didn't
take into consideration that same num is used later in devm_kcalloc().
If "intel,vm-map" does exist there is no need to set the unspecified
channels with incremental numbers, because the unspecified channels
can't be accessed in pvt_read_in() which is the only other place besides
the probe functions that uses pvt->vm_idx[].
This change fixes the bug by moving the incremental channel numbers
setting to be done only if "intel,vm-map" property is defined (starting
loop from 0), and removing 'num = 0'.
