Merge tag 'for-6.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Split dm-bufio's rw_semaphore and rbtree. Offers improvements to
dm-bufio's locking to allow increased concurrent IO -- particularly
for read access for buffers already in dm-bufio's cache.

- Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim
at improving concurrent IO (for the DM thinp target).

- Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks
and rbtrees used are managed by dm_num_hash_locks(). And the hash
function used by both is dm_hash_locks_index().

- Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to
be split at the target specified boundary (in terms of
max_discard_sectors, max_write_zeroes_sectors and
max_secure_erase_sectors respectively).

- DM verity error handling fix for check_at_most_once on FEC.

- Update DM verity target to emit audit events on verification failure
and more.

- DM core ->io_hints improvements needed in support of new discard
support that is added to the DM "zero" and "error" targets.

- Fix missing kmem_cache_destroy() call in initialization error path of
both the DM integrity and DM clone targets.

- A couple fixes for DM flakey, also add "error_reads" feature.

- Fix DM core's resume to not lock FS when the DM map is NULL;
otherwise initial table load can race with FS mount that takes
superblock's ->s_umount rw_semaphore.

- Various small improvements to both DM core and DM targets.

KVM/arm64 updates for 6.4

- Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.

- New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features
being moved to VMMs rather than be implemented in the kernel.

- Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one.
This last part allows the NV timer code to be implemented on
top.

- A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.

- The usual selftest fixes and improvements.

Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:

This patch series introduces support for the Rockchip RK860X regulators,
while also providing a few fixes and improvements to the existing fan53555
driver.

RK8600/RK8601 are quite similar to the FAN53555 regulators.

RK8602/RK8603 are a bit different, having a wider output voltage
selection range, from 0.5 V to 1.5 V in 6.25 mV steps. They are used
in the Rock 5B board to power the ARM Cortex-A76 cores and the NPU.

dm: split discards further if target sets max_discard_granularity

The block core (bio_split_discard) will already split discards based
on the 'discard_granularity' and 'max_discard_sectors' queue_limits.
But the DM thin target also needs to ensure that it doesn't receive a
discard that spans a 'max_discard_sectors' boundary.

Introduce a dm_target 'max_discard_granularity' flag that if set will
cause DM core to split discard bios relative to 'max_discard_sectors'.
This treats 'discard_granularity' as a "min_discard_granularity" and
'max_discard_sectors' as a "max_discard_granularity".

dm: fix __send_duplicate_bios() to always allow for splitting IO

Commit 7dd76d1feec70 ("dm: improve bio splitting and associated IO
accounting") only called setup_split_accounting() from
__send_duplicate_bios() if a single bio were being issued. But the case
where duplicate bios are issued must call it too.

Otherwise the bio won't be split and resubmitted (via recursion through
block core back to DM) to submit the later portions of a bio (which may
map to an entirely different target).

For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048

Before (broken, discards the first striped target's devices twice):
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528

After (works as expected):
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528

dm: fix improper splitting for abnormal bios

"Abnormal" bios include discards, write zeroes and secure erase. By no
longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm:
allow dm_accept_partial_bio() for dm_io without duplicate bios") took a
senseless approach to disallowing dm_accept_partial_bio() from working
for duplicate bios processed using __send_duplicate_bios().

It inadvertently and incorrectly stopped the use of 'len' when
initializing a target's io (in alloc_tio). As such the resulting tio
could address more area of a device than it should.

For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048

Before this fix:

device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=102400
blkdiscard: attempt to access beyond end of device
loop0: rw=2051, sector=2048, nr_sectors = 102400 limit=81920

device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=102400
blkdiscard: attempt to access beyond end of device
loop1: rw=2051, sector=2048, nr_sectors = 102400 limit=81920

After this fix;

device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
