a5d862da91 ath5k: switch to rate table based lookup 
Switching from legacy usage of ieee80211_get_tx_rates() lookup to direct
rate table lookup in struct ieee80211_sta->rates.

The current rate control API allows drivers to directly get rates from
ieee80211_sta->rates. ath5k is currently one of the legacy drivers that
perform translation/merge with the internal rate table via
ieee80211_get_tx_rates provided by rate control API.
For our upcoming changes to rate control API and the implementation of
transmit power control, this patch changes the behaviour. The call to
ieee80211_get_tx_rates and subsequent calls are also avoided. ath5k now
directly reads rates from sta->rates into its internal rate table. Cause
ath5k does not rely on the rate array in SKB->CB, this is not considered
anymore except for the first entry (used for probing).

Tested this on a PCEngines ALIX with CMP9-GP miniPCI wifi card (Atheros
AR5213A). Generated traffic between AP and multiple STAs before and
after applying the patch and simultaneously measured throughput and
captured rc_stats. Comparison resulted in same rate selection and no
performance loss between both runs.

712fe4c849 serial: sh-sci: Remove BREAK/FRAME/PARITY/OVERRUN printouts 
Update the SCIF serial driver to remove printouts for break, frame, parity
and overrun errors. This reduces the amount of console printouts generated
by the defconfig kernel on R-Car Gen3 for certain use cases. To retrieve
more information about such errors the user may inspect counters. Also these
errors are fed into the TTY layer for further application specific handling.

8cf8d3c4a6 tty: serial: samsung: Fix console registration from module 
On modern Exynos SoCs (like Exynos850) the UART can be implemented as a
part of USI IP-core. In such case, USI driver is used to initialize USI
registers, and it also calls of_platform_populate() to instantiate all
sub-nodes (e.g. serial node) of USI node. When serial driver is
built-in, but USI driver is a module, and CONFIG_SERIAL_SAMSUNG_CONSOLE
is enabled, next call chain will happen when loading USI module from
user space:

    usi_init
      v
    usi_probe
      v
    of_platform_populate
      v
    s3c24xx_serial_probe
      v
    uart_add_one_port
      v
    uart_configure_port
      v
    register_console
      v
    try_enable_new_console
      v
    s3c24xx_serial_console_setup

But because the serial driver is built-in, and
s3c24xx_serial_console_setup() is marked with __init keyword, that
symbol will discarded and long gone by that time already, causing failed
paging request.

That happens during the next config combination:

    EXYNOS_USI=m
    SERIAL_SAMSUNG=y
    SERIAL_SAMSUNG_CONSOLE=y

That config should be completely possible, so rather than limiting
SERIAL_SAMSUNG choice to "m" only when USI=m, remove __init keyword for
all affected functions.

9606ca2ea1 drm/i915: Ensure i915_vma tests do not get -ENOSPC with the locking changes. 
Now that we require locking to evict, multiple vmas from the same object
might not be evicted. This is expected and required, because execbuf will
move to short-term pinning by using the lock only. This will cause these
tests to fail, because they create a ton of vma's for the same object.

Unbind manually to prevent spurious -ENOSPC in those mock tests.

fd06ccf159 drm/i915: Ensure gem_contexts selftests work with unbind changes, v2. 
In the next commits, we may not evict when refcount = 0.

igt_vm_isolation() continuously tries to pin/unpin at same address,
but also calls put() on the object, which means the object may not
be unpinned in time.

Instead of this, re-use the same object over and over, so they can
be unbound as required.

Changes since v1:
- Fix cleaning up obj_b on failure. (Matt)

0b4d1f0e93 drm/i915: Remove pages_mutex and intel_gtt->vma_ops.set/clear_pages members, v3. 
Big delta, but boils down to moving set_pages to i915_vma.c, and removing
the special handling, all callers use the defaults anyway. We only remap
in ggtt, so default case will fall through.

Because we still don't require locking in i915_vma_unpin(), handle this by
using xchg in get_pages(), as it's locked with obj->mutex, and cmpxchg in
unpin, which only fails if we race a against a new pin.

Changes since v1:
- aliasing gtt sets ZERO_SIZE_PTR, not -ENODEV, remove special case
  from __i915_vma_get_pages(). (Matt)
Changes since v2:
- Free correct old pages in __i915_vma_get_pages(). (Matt)
  Remove race of clearing vma->pages accidentally from put,
  free it but leave it set, as only get has the lock.

e4e8062530 drm/i915: Change shrink ordering to use locking around unbinding. 
Call drop_pages with the gem object lock held, instead of the other
way around. This will allow us to drop the vma bindings with the
gem object lock held.

We plan to require the object lock for unpinning in the future,
and this is an easy target.

9593bdfa1d Samsung SoC drivers changes for v5.17 
1. Exynos ChipID: add Exynos7885 support.
 2. Exynos PMU: add Exynos850 support.
 3. Minor bindings cleanup.
 4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
    a shared IP block between I2C, UART/serial and SPI. Basically one has
    to choose which feature the USI block will support and later the
    regular I2C/serial/SPI driver will bind and work.
    This merges also one commit with dt-binding headers from my dts64
    pull request.
 
    Together with a future serial driver change, this will break the ABI.
 
    Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards
 
    Why: To properly and efficiently support the USI with new hierarchy
    of USI-{serial,SPI,I2C} devicetree nodes.
 
    Rationale:
    Recently added serial and USI support was short-sighted and did not
    allow to smooth support of other features (SPI and I2C). Adding
    support for USI-SPI and USI-I2C would effect in code duplication.
    Adding support for different USI versions (currently supported is
    USIv2 but support for v1 is planned) would cause even more code
    duplication and create a solution difficult to maintain.
    Since USI-serial and ExynosAutov9 have been added recently, are
    considered fresh development features and there are no supported
    products using them, the code/solution is being refactored in
    non-backwards compatible way.  The compatibility is not broken yet.
    It will be when serial driver changes are accepted.
    The ABI break was discussed with only known users of ExynosAutov9 and
    received their permission.

484730e586 parisc: Clear stale IIR value on instruction access rights trap 
When a trap 7 (Instruction access rights) occurs, this means the CPU
couldn't execute an instruction due to missing execute permissions on
the memory region.  In this case it seems the CPU didn't even fetched
the instruction from memory and thus did not store it in the cr19 (IIR)
register before calling the trap handler. So, the trap handler will find
some random old stale value in cr19.

This patch simply overwrites the stale IIR value with a constant magic
"bad food" value (0xbaadf00d), in the hope people don't start to try to
understand the various random IIR values in trap 7 dumps.

soc/tegra: Changes for v5.17-rc1

This set of changes contains some preparatory work that is shared by
several branches and trees to support DVFS via power domains.

There's also a bit of cleanup and improvements to reboot on chips that
use PSCI.

ab1ef34416 KVM: selftests: Add test to verify TRIPLE_FAULT on invalid L2 guest state 
Add a selftest to attempt to enter L2 with invalid guests state by
exiting to userspace via I/O from L2, and then using KVM_SET_SREGS to set
invalid guest state (marking TR unusable is arbitrary chosen for its
relative simplicity).

This is a regression test for a bug introduced by commit c8607e4a08
("KVM: x86: nVMX: don't fail nested VM entry on invalid guest state if
!from_vmentry"), which incorrectly set vmx->fail=true when L2 had invalid
guest state and ultimately triggered a WARN due to nested_vmx_vmexit()
seeing vmx->fail==true while attempting to synthesize a nested VM-Exit.

The is also a functional test to verify that KVM sythesizes TRIPLE_FAULT
for L2, which is somewhat arbitrary behavior, instead of emulating L2.
KVM should never emulate L2 due to invalid guest state, as it's
architecturally impossible for L1 to run an L2 guest with invalid state
as nested VM-Enter should always fail, i.e. L1 needs to do the emulation.
Stuffing state via KVM ioctl() is a non-architctural, out-of-band case,
hence the TRIPLE_FAULT being rather arbitrary.

0ff29701ff KVM: VMX: Fix stale docs for kvm-intel.emulate_invalid_guest_state 
Update the documentation for kvm-intel's emulate_invalid_guest_state to
rectify the description of KVM's default behavior, and to document that
the behavior and thus parameter only applies to L1.
