regulator: Switch two more i2c drivers back to use .probe()
The previous conversion back to .probe done in commit 964e186547
("regulator: Switch i2c drivers back to use .probe()") was done based on
v6.3. Since then two more drivers were added which need to be convert
back in the same way before eventually .probe_new() can be dropped from
struct i2c_driver.

TI TPS6594 PMIC support (RTC, pinctrl, regulators)
Merge series from Esteban Blanc <eblanc@baylibre.com>:

TPS6594 is a Power Management IC which provides regulators and others
features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC can
communicate through the I2C or SPI interfaces.
TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives.

This series adds support to TI TPS6594 PMIC and its derivatives.

spi-geni-qcom: Add new interfaces and utilise them
Merge series from Vijaya Krishna Nivarthi <quic_vnivarth@quicinc.com>:

A "known issue" during implementation of SE DMA for spi geni driver was
that it does DMA map/unmap internally instead of in spi framework.
Current patches remove this hiccup and also clean up code a bit.

Testing revealed no regressions and results with 1000 iterations of
reading from EC showed no loss of performance.
Results
=======
Before - Iteration 999, min=5.10, max=5.17, avg=5.14, ints=25129
After  - Iteration 999, min=5.10, max=5.20, avg=5.15, ints=25153

spi: spi-geni-qcom: Do not do DMA map/unmap inside driver, use framework instead
The spi geni driver in SE DMA mode, unlike GSI DMA, is not making use of
DMA mapping functionality available in the framework.
The driver does mapping internally which makes dma buffer fields available
in spi_transfer struct superfluous while requiring additional members in
spi_geni_master struct.

Conform to the design by having framework handle map/unmap and do only
DMA transfer in the driver; this also simplifies code a bit.

soc: qcom: geni-se: Add interfaces geni_se_tx_init_dma() and geni_se_rx_init_dma()
The geni_se_xx_dma_prep() interfaces necessarily do DMA mapping before
initiating DMA transfers. This is not suitable for spi where framework
is expected to handle map/unmap.

Expose new interfaces geni_se_xx_init_dma() which do only DMA transfer.

regulator: tps6594-regulator: Add driver for TI TPS6594 regulators
This patch adds support for TPS6594 regulators (bucks and LDOs).
The output voltages are configurable and are meant to supply power
to the main processor and other components.
Bucks can be used in single or multiphase mode, depending on PMIC
part number.

regulator: Add X-Powers AXP15060/AXP313a PMIC
Merge series from Andre Przywara <andre.przywara@arm.com>:

This patch series adds support for the X-Powers AXP15060 and AXP313a
PMIC, which are general purpose PMICs as seen on different boards with
different SOCs, mostly from Allwinner.

This is mostly a repost of the previous patches, combining both the
AXP313a and AXP15060 series, rebased on top of v6.4-rc3, and omitting
the patches that already got merged.
The first two patches are the successors of the AXP313a v10 post,
the third patch is based on Shengyu's AXP15060 v3 post.

There were no code changes, just some tiny context differences due to
the rebase, plus I added the newly gained tags.

As the DT bindings and the AXP15060 MFD part are already in the tree,
this is just completing support with the MFD part for the AXP313a, and
the regulator support for both PMICs.

b05d39466b leds: qcom-lpg: Fix PWM period limits
The introduction of high resolution PWM support changed the order of the
operations in the calculation of min and max period. The result in both
divisions is in most cases a truncation to 0, which limits the period to
the range of [0, 0].

Both numerators (and denominators) are within 64 bits, so the whole
expression can be put directly into the div64_u64, instead of doing it
partially.

Choose the target function for the filter test from the sample
event data so that it can keep test running correctly even if the caller

47d2804bc9 KVM: selftests: Add test for race in kvm_recalculate_apic_map()
Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during
APIC map construction to hunt for TOCTOU bugs in KVM.  KVM's optimized map
recalc makes multiple passes over the list of vCPUs, and the calculations
ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where
toggling LAPIC_MODE_DISABLED is quite interesting.

4364b28798 KVM: x86: Bail from kvm_recalculate_phys_map() if x2APIC ID is out-of-bounds
Bail from kvm_recalculate_phys_map() and disable the optimized map if the
target vCPU's x2APIC ID is out-of-bounds, i.e. if the vCPU was added
and/or enabled its local APIC after the map was allocated.  This fixes an
out-of-bounds access bug in the !x2apic_format path where KVM would write
beyond the end of phys_map.

Check the x2APIC ID regardless of whether or not x2APIC is enabled,
as KVM's hardcodes x2APIC ID to be the vCPU ID, i.e. it can't change, and
the map allocation in kvm_recalculate_apic_map() doesn't check for x2APIC
being enabled, i.e. the check won't get false postivies.

Note, this also affects the x2apic_format path, which previously just
ignored the "x2apic_id > new->max_apic_id" case.  That too is arguably a
bug fix, as ignoring the vCPU meant that KVM would not send interrupts to
the vCPU until the next map recalculation.  In practice, that "bug" is
likely benign as a newly present vCPU/APIC would immediately trigger a
recalc.  But, there's no functional downside to disabling the map, and
a future patch will gracefully handle the -E2BIG case by retrying instead
of simply disabling the optimized map.

Opportunistically add a sanity check on the xAPIC ID size, along with a
comment explaining why the xAPIC ID is guaranteed to be "good".

b2ce899788 KVM: SVM: vNMI pending bit is V_NMI_PENDING_MASK not V_NMI_BLOCKING_MASK
While testing Hyper-V enabled Windows Server 2019 guests on Zen4 hardware
I noticed that with vCPU count large enough (> 16) they sometimes froze at
boot.
With vCPU count of 64 they never booted successfully - suggesting some kind
of a race condition.

Since adding "vnmi=0" module parameter made these guests boot successfully
it was clear that the problem is most likely (v)NMI-related.

Running kvm-unit-tests quickly showed failing NMI-related tests cases, like
"multiple nmi" and "pending nmi" from apic-split, x2apic and xapic tests
and the NMI parts of eventinj test.

The issue was that once one NMI was being serviced no other NMI was allowed
to be set pending (NMI limit = 0), which was traced to
svm_is_vnmi_pending() wrongly testing for the "NMI blocked" flag rather
than for the "NMI pending" flag.

Fix this by testing for the right flag in svm_is_vnmi_pending().
Once this is done, the NMI-related kvm-unit-tests pass successfully and
the Windows guest no longer freezes at boot.

817fa99836 KVM: x86/mmu: Grab memslot for correct address space in NX recovery worker
Factor in the address space (non-SMM vs. SMM) of the target shadow page
when recovering potential NX huge pages, otherwise KVM will retrieve the
wrong memslot when zapping shadow pages that were created for SMM.  The
bug most visibly manifests as a WARN on the memslot being non-NULL, but
the worst case scenario is that KVM could unaccount the shadow page
without ensuring KVM won't install a huge page, i.e. if the non-SMM slot
is being dirty logged, but the SMM slot is not.

This bug was exposed by commit edbdb43fc9 ("KVM: x86: Preserve TDP MMU
roots until they are explicitly invalidated"), which allowed KVM to retain
SMM TDP MMU roots effectively indefinitely.  Before commit edbdb43fc9,
KVM would zap all SMM TDP MMU roots and thus all SMM TDP MMU shadow pages
once all vCPUs exited SMM, which made the window where this bug (recovering
an SMM NX huge page) could be encountered quite tiny.  To hit the bug, the
NX recovery thread would have to run while at least one vCPU was in SMM.
Most VMs typically only use SMM during boot, and so the problematic shadow
pages were gone by the time the NX recovery thread ran.

Now that KVM preserves TDP MMU roots until they are explicitly invalidated
(e.g. by a memslot deletion), the window to trigger the bug is effectively
never closed because most VMMs don't delete memslots after boot (except
for a handful of special scenarios).

4ecd704a4c tpm, tpm_tis: correct tpm_tis_flags enumeration values
With commit 858e8b792d ("tpm, tpm_tis: Avoid cache incoherency in test
for interrupts") bit accessor functions are used to access flags in
tpm_tis_data->flags.

However these functions expect bit numbers, while the flags are defined
as bit masks in enum tpm_tis_flag.

Fix this inconsistency by using numbers instead of masks also for the
flags in the enum.

3582e74599 Revert "ext4: remove ac->ac_found > sbi->s_mb_min_to_scan dead check in ext4_mb_check_limits"
This reverts commit 32c0869370.

The reverted commit was intended to remove a dead check however it was observed
that this check was actually being used to exit early instead of looping
sbi->s_mb_max_to_scan times when we are able to find a free extent bigger than
the goal extent. Due to this, a my performance tests (fsmark, parallel file
writes in a highly fragmented FS) were seeing a 2x-3x regression.

Example, the default value of the following variables is:

sbi->s_mb_max_to_scan = 200
sbi->s_mb_min_to_scan = 10

In ext4_mb_check_limits() if we find an extent smaller than goal, then we return
early and try again. This loop will go on until we have processed
sbi->s_mb_max_to_scan(=200) number of free extents at which point we exit and
just use whatever we have even if it is smaller than goal extent.

Now, the regression comes when we find an extent bigger than goal. Earlier, in
this case we would loop only sbi->s_mb_min_to_scan(=10) times and then just use
the bigger extent. However with commit 32c08693 that check was removed and hence
we would loop sbi->s_mb_max_to_scan(=200) times even though we have a big enough
free extent to satisfy the request. The only time we would exit early would be
when the free extent is *exactly* the size of our goal, which is pretty uncommon
occurrence and so we would almost always end up looping 200 times.

Hence, revert the commit by adding the check back to fix the regression. Also
add a comment to outline this policy.

81f3affa19 media: uvcvideo: Don't expose unsupported formats to userspace
When the uvcvideo driver encounters a format descriptor with an unknown
format GUID, it creates a corresponding struct uvc_format instance with
the fcc field set to 0. Since commit 50459f103e ("media: uvcvideo:
Remove format descriptions"), the driver relies on the V4L2 core to
provide the format description string, which the V4L2 core can't do
without a valid 4CC. This triggers a WARN_ON.

As a format with a zero 4CC can't be selected, it is unusable for
applications. Ignore the format completely without creating a uvc_format
instance, which fixes the warning.

regulator: axp20x: Add AXP15060 support
The AXP15060 is a typical I2C-controlled PMIC, seen on multiple boards
with different default register value. Current driver is tested on
Starfive Visionfive 2.

The RTCLDO is fixed, and cannot even be turned on or off. On top of
that, its voltage is customisable (either 1.8V or 3.3V). We pretend it's
a fixed 1.8V regulator since other AXP driver also do like this. Also,
BSP code ignores this regulator and it's not used according to VF2
schematic.

Describe the AXP15060's voltage settings and switch registers, how the
voltages are encoded, and connect this to the MFD device via its
regulator ID.

regulator: axp20x: Add support for AXP313a variant
The AXP313a is your typical I2C controlled PMIC, although in a lighter
fashion compared to the other X-Powers PMICs: it has only three DCDC
rails, three LDOs, and no battery charging support.

The AXP313a datasheet does not describe a register to change the DCDC
switching frequency, and talks of it being fixed at 3 MHz. Check that
the property allowing to change that frequency is absent from the DT,
and bail out otherwise.

The third LDO, RTCLDO, is fixed, and cannot even be turned on or off,
programmatically. On top of that, its voltage is customisable (either
1.8V or 3.3V), which we cannot describe easily using the existing
regulator wrapper functions. This should be fixed properly, using
regulator-{min,max}-microvolt in the DT, but this requires more changes
to the code. As some other PMICs (AXP2xx, AXP803) seem to paper over the
same problem as well, we follow suit here and pretend it's a fixed 1.8V
regulator. A proper fix can follow later. The BSP code seems to ignore
this regulator altogether.

Describe the AXP313A's voltage settings and switch registers, how the
voltages are encoded, and connect this to the MFD device via its
regulator ID.

riscv: Fix huge_ptep_set_wrprotect when PTE is a NAPOT
We need to avoid inconsistencies across the PTEs that form a NAPOT
region, so when we write protect such a region, we should clear and flush
all the PTEs to make sure that any of those PTEs is not cached which would
result in such inconsistencies (arm64 does the same).
