2d505453f3 drm/amdgpu: conduct a proper cleanup of PDB bo

32f90e6525 drm/amdgpu: prevent memory wipe in suspend/shutdown stage
On GPUs with RAS enabled, below call trace is observed when
suspending or shutting down device. The cause is we have enabled
memory wipe flag for BOs on such GPUs by default, and such BOs
will go to memory wipe by amdgpu_fill_buffer, however, because
ring is off already, it fails to clean up the memory and throw
this error message. So add a suspend/shutdown check before
wipping memory.

[drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off.

v2: fix coding style issue

d97c68d178 random: treat bootloader trust toggle the same way as cpu trust toggle
If CONFIG_RANDOM_TRUST_CPU is set, the RNG initializes using RDRAND.
But, the user can disable (or enable) this behavior by setting
`random.trust_cpu=0/1` on the kernel command line. This allows system
builders to do reasonable things while avoiding howls from tinfoil
hatters. (Or vice versa.)

CONFIG_RANDOM_TRUST_BOOTLOADER is basically the same thing, but regards
the seed passed via EFI or device tree, which might come from RDRAND or
a TPM or somewhere else. In order to allow distros to more easily enable
this while avoiding those same howls (or vice versa), this commit adds
the corresponding `random.trust_bootloader=0/1` toggle.

af704c856e random: skip fast_init if hwrng provides large chunk of entropy
At boot time, EFI calls add_bootloader_randomness(), which in turn calls
add_hwgenerator_randomness(). Currently add_hwgenerator_randomness()
feeds the first 64 bytes of randomness to the "fast init"
non-crypto-grade phase. But if add_hwgenerator_randomness() gets called
with more than POOL_MIN_BITS of entropy, there's no point in passing it
off to the "fast init" stage, since that's enough entropy to bootstrap
the real RNG. The "fast init" stage is just there to provide _something_
in the case where we don't have enough entropy to properly bootstrap the
RNG. But if we do have enough entropy to bootstrap the RNG, the current
logic doesn't serve a purpose. So, in the case where we're passed
greater than or equal to POOL_MIN_BITS of entropy, this commit makes us
skip the "fast init" phase.

631f871f07 fs/iomap: Fix buffered write page prefaulting
When part of the user buffer passed to generic_perform_write() or
iomap_file_buffered_write() cannot be faulted in for reading, the entire
write currently fails.  The correct behavior would be to write all the
data that can be written, up to the point of failure.

Commit a6294593e8 ("iov_iter: Turn iov_iter_fault_in_readable into
fault_in_iov_iter_readable") gave us the information needed, so fix the
page prefaulting in generic_perform_write() and iomap_write_iter() to
only bail out when no pages could be faulted in.

We already factor in that pages that are faulted in may no longer be
resident by the time they are accessed.  Paging out pages has the same
effect as not faulting in those pages in the first place, so the code
can already deal with that.

52dd86406d io_uring: enable EPOLLEXCLUSIVE for accept poll
When polling sockets for accept, use EPOLLEXCLUSIVE. This is helpful
when multiple accept SQEs are submitted.

For O_NONBLOCK sockets multiple queued SQEs would previously have all
completed at once, but most with -EAGAIN as the result. Now only one
wakes up and completes.

For sockets without O_NONBLOCK there is no user facing change, but
internally the extra requests would previously be queued onto a worker
thread as they would wake up with no connection waiting, and be
punted. Now they do not wake up unnecessarily.

59ab4ee012 drm/qxl: fix qxl can't use in arm64
qxl use ioremap to map ram_header and rom, in the arm64 implementation,
the device is mapped as DEVICE_nGnRE, it can not support unaligned
access. and qxl is a virtual device, it can be treated more like RAM
than actual MMIO registers. use ioremap_wc() replace it.

ec3cbb3089 drm/virtio: Remove restriction of non-zero blob_flags
With native userspace drivers in guest, a lot of GEM objects need to be
neither shared nor mappable.  And in fact making everything mappable
and/or sharable results in unreasonably high fd usage in host VMM.

Having !allow_set_time is equivalent to non-implemented set_time
function, which is normally represented with -ENODEV error in RTC
subsystem.

Today we are returning -EACCES error code, which is not considered
by RTC clients as a 'non implemented' feature, and which causes NTP
to retry hw clk sync (update_rtc) indefinitely.

7b0c70d92a ath11k: Add peer rhash table support
When more clients (128) are connected, the UL data traffic
KPI measurement is low compared to single client. This issue
is due to more CPU cycles spent on the peer lookup operation
with more clients. So reduce the peer lookup operation by
modifying the linear based lookup operation into the rhash
based lookup operation. This improve the peak throughput
measurement. Since this is a software algorithm change, it is
applicable for all the platforms.

TCP UL 128 Clients test case Observation (64bit system):
Previous: ~550 Mbps
Now	: ~860 Mbps

Add fallback board name which removed variant value and search again

data again to increase boot up success rate.

because the number of #clock-cells is unknown in the previous entry.
Solve this by adding the clock provider node. Only 'cpg_clocks' is
needed as the examples are built with fixups which can be used to
identify phandles.

This is in preparation to support schema validation on .dtb files.

25fd2d41b5 selftests: kselftest framework: provide "finished" helper
Instead of having each time that wants to use ksft_exit() have to figure
out the internals of kselftest.h, add the helper ksft_finished() that
makes sure the passes, xfails, and skips are equal to the test plan count.

9457056ac4 mm: madvise: MADV_DONTNEED_LOCKED
MADV_DONTNEED historically rejects mlocked ranges, but with MLOCK_ONFAULT
and MCL_ONFAULT allowing to mlock without populating, there are valid use
cases for depopulating locked ranges as well.

Users mlock memory to protect secrets.  There are allocators for secure
buffers that want in-use memory generally mlocked, but cleared and
invalidated memory to give up the physical pages.  This could be done with
explicit munlock -> mlock calls on free -> alloc of course, but that adds
two unnecessary syscalls, heavy mmap_sem write locks, vma splits and
re-merges - only to get rid of the backing pages.

Users also mlockall(MCL_ONFAULT) to suppress sustained paging, but are
okay with on-demand initial population.  It seems valid to selectively
free some memory during the lifetime of such a process, without having to
mess with its overall policy.

Why add a separate flag? Isn't this a pretty niche usecase?

- MADV_DONTNEED has been bailing on locked vmas forever. It's at least
  conceivable that someone, somewhere is relying on mlock to protect
  data from perhaps broader invalidation calls. Changing this behavior
  now could lead to quiet data corruption.

- It also clarifies expectations around MADV_FREE and maybe
  MADV_REMOVE. It avoids the situation where one quietly behaves
  different than the others. MADV_FREE_LOCKED can be added later.

- The combination of mlock() and madvise() in the first place is
  probably niche. But where it happens, I'd say that dropping pages
  from a locked region once they don't contain secrets or won't page
  anymore is much saner than relying on mlock to protect memory from
  speculative or errant invalidation calls. It's just that we can't
  change the default behavior because of the two previous points.

Given that, an explicit new flag seems to make the most sense.
