Add macro definition to support update_mmu_tlb() for riscv,
this function is from commit:7df676974359 ("mm/memory.c:Update
local TLB if PTE entry exists").
update_mmu_tlb() is used when a thread notice that other cpu thread
has handled the fault and changed the PTE. For MIPS, it's worth to
do that,this cpu thread will trap in tlb fault again otherwise.
For RISCV, it's also better to flush local tlb than do nothing in
update_mmu_tlb(). There are two kinds of page fault that have
update_mmu_tlb() inside:
1.page fault which PTE is NOT none, only protection check error,
like write protection fault. If updata_mmu_tlb() is empty, after
finsh page fault this time and re-execute, cpu will find address
but protection checked error in tlb again. So this will cause
another page fault. PTE in memory is good now,so update_mmu_cache()
in handle_pte_fault() will be executed. If updata_mmu_tlb() is not
empty flush local tlb, cpu won't find this address in tlb next time,
and get entry in physical memory, so it won't cause another page
fault.
2.page fault which PTE is none or swapped.
For this case, this cpu thread won't cause another page fault,cpu
will have tlb miss when re-execute, and get entry in memory
directly. But "set pte in phycial memory and flush local tlb" is
pratice in Linux, it's better to flush local tlb if it find entry
in phycial memory has changed.
Maybe it's same for other ARCH which can't detect PTE changed and
update it in local tlb automatically.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Existing HDaudio controllers expose an HDAudio DMA which is used to
interface with HDaudio codecs. All other interfaces supported by Intel
(SoundWire, SSP, DMIC) rely for data transfers on another GP-DMA
managed by the DSP firmware - the HDaudio DMA is only used for
memory-to-DSP transfers.
New HDaudio extensions will enable the use of this HDaudio DMA for all
of SoundWire, SSP, DMIC. These extensions will be backwards-compatible
for HDaudio and iDISP codecs, but will require new programming
sequences and DAI callbacks for SoundWire, SSP and DMIC.
Before we add support for 'extended audio links' and the programming
sequences for the DMA, we need to refactor the code. All HDaudio codec
support needs to be well identified in a separate file, and likewise
all the 'multi-link' handling needs to be better split.
This patchset removes a number of 'old' Kconfig dependencies and
options, adds helpers with a fallback to remove IS_ENABLED checks in
the code and tries to simplify programming sequences when possible.
One indirect benefit from this refactoring is that developers can
switch with a kernel parameter from HDaudio support to a variant of
'nocodec' support. This proves extremely useful to test on existing
Intel RVPs and Up boards, where the same build can be used to check 3
interfaces (HDaudio, SSP, DMIC) by just removing modules, setting the
kernel parameter and reloading modules.

Even though the overflow can never happen (the maximum number of pages of
the HFI table is 0x10 and 0x10 << PAGE_SHIFT = 0x10000), using size_t as

While we correctly skips to initialize an idle state from a disabled idle
state node in DT, the returned value from dt_init_idle_driver() don't get
adjusted accordingly. Instead the number of found idle state nodes are
returned, while the callers are expecting the number of successfully
initialized idle states from DT.
This leads to cpuidle drivers unnecessarily continues to initialize their
idle state specific data. Moreover, in the case when all idle states have
been disabled in DT, we would end up registering a cpuidle driver, rather
than relying on the default arch specific idle call.

doorbells for all channels with a delta in TRE rings assuming

it by adding a channel enabled check before ringing channel

Pull crypto fix from Herbert Xu:
"Fix an alignment crash in x86/polyval"
* tag 'v6.1-p3' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: x86/polyval - Fix crashes when keys are not 16-byte aligned
Some documentation first, about how this machinery works:
It seems, the intent of the GHES error records cache is to collect
already reported errors - see the ghes_estatus_cached() checks. There's
even a sentence trying to say what this does:
/*
* GHES error status reporting throttle, to report more kinds of
* errors, instead of just most frequently occurred errors.
*/
New elements are added to the cache this way:
if (!ghes_estatus_cached(estatus)) {
if (ghes_print_estatus(NULL, ghes->generic, estatus))
ghes_estatus_cache_add(ghes->generic, estatus);
The intent being, once this new error record is reported, it gets cached
so that it doesn't get reported for a while due to too many, same-type
error records getting reported in burst-like scenarios. I.e., new,
unreported error types can have a higher chance of getting reported.
Now, the loop in ghes_estatus_cache_add() is trying to pick out the
oldest element in there. Meaning, something which got reported already
but a long while ago, i.e., a LRU-type scheme.
And the cmpxchg() is there presumably to make sure when that selected
element slot_cache is removed, it really *is* that element that gets
removed and not one which replaced it in the meantime.
Now, ghes_estatus_cache_add() selects a slot, and either succeeds in
replacing its contents with a pointer to a newly cached item, or it just
gives up and frees the new item again, without attempting to select
another slot even if one might be available.
Since only inserting new items is being done here, the race can only
cause a failure if the selected slot was updated with another new item
concurrently, which means that it is arbitrary which of those two items
gets dropped.
And "dropped" here means, the item doesn't get added to the cache so
the next time it is seen, it'll get reported again and an insertion
attempt will be done again. Eventually, it'll get inserted and all those
times when the insertion fails, the item will get reported although the
cache is supposed to prevent that and "ratelimit" those repeated error
records. Not a big deal in any case.
This means the cmpxchg() and the special case are not necessary.
Therefore, just drop the existing item unconditionally.
Move the xchg_release() and call_rcu() out of rcu_read_lock/unlock
section since there is no actually dereferencing the pointer at all.
[ bp:
- Flesh out and summarize what was discussed on the thread now
that that cache contraption is understood;
- Touch up code style. ]

Stan is moving out of mm-sol and decided not to carry on the maintainership
duties of the Qcom PCIe RC driver. Since I'm already maintaining the Qcom
PCIe EP driver, I'm volunteering myself to maintain the RC driver also.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Goal of the series is implementation of suspend/resume operations for a
PCM stream along with all the collaterals connected to the subject.
Start with splitting avs_dai_fe_hw_free() as ideally we would like to
reuse as much of existing code as possible but snd_pcm_lib_free_pages()
is not desired part of the function when speaking of suspend operation.
The actual implementation of suspend/resume() for component drivers
follows. For most scenarios, the PM flow is similar to standard
streaming one, except for the part where the position register are being
saved and the lack of PCM pages freeing. To reduce code duplication, all
avs_dai_suspend_XXX() and avs_dai_resume_XXX() functions reuse their
non-PM equivalents.
Order of operations is affected by the fact that path binding/unbinding
happens only in FE part of the stream.
Above essentially unlocks SX+streaming scenarios i.e.: power transitions
with an ongoing stream.
As some streams are allowed to run in low power state, support is
provided for S0iX state. The handlers check ACPI capabilities and the
number of active low-power paths before deciding between SX and S0iX
flows.
The last portion of the patchset is addition of power/clock gating
overrides. There is no single set of registers that ensures AudioDSP
firmware loads 100% of time on every single configuration. By having
them exposed, user can have the loading procedure behavior adjusted for
their configuration without having to recompile the kernel.
Since commit 0998d06310 ("device-core: Ensure drvdata = NULL when no
driver is bound") the driver core cares for cleaning driver data, so
don't do it in the driver, too.

The following error messages are observed on boot for Tegra234 ...
ERR KERN tegra-qspi 3270000.spi: cannot use DMA: -19
ERR KERN tegra-qspi 3270000.spi: falling back to PIO
Tegra234 does not support DMA for the QSPI and so initialising the DMA
is expected to fail. The above error messages are misleading for devices
that don't support DMA and so fix this by skipping the DMA
initialisation for devices that don't support DMA.

Commit 8a254d90a7 ("efi: efivars: Fix variable writes without
query_variable_store()") addressed an issue that was introduced during
the EFI variable store refactor, where alternative implementations of
the efivars layer that lacked query_variable_store() would no longer
work.
Unfortunately, there is another case to consider here, which was missed:
if the efivars layer is backed by the EFI runtime services as usual, but
the EFI implementation predates the introduction of QueryVariableInfo(),
we will return EFI_UNSUPPORTED, and this is no longer being dealt with
correctly.
So let's fix this, and while at it, clean up the code a bit, by merging
the check_var_size() routines as well as their callers.

AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.
This support is needed for more detailed graphs like ECNS, speaker
protection and so.
