During module probe, regulator 'vin' and 'vdd-io' are used and enabled,
but the vdd-io regulator overwrites the 'vin' regulator pointer. During
remove, only the vdd-io is disabled, as the vin regulator pointer is not
available anymore. When regulator_put() is called during resource
cleanup a kernel warning is given, as the regulator is still enabled.
Store the two regulators in separate pointers and disable both the
regulators on module remove.

With the recent PHYLINK changes requiring supported_interfaces to be set,
MV88E6250 family switches like the 88E6020 fail to probe - cmode is
never initialized on these devices, so mv88e6250_phylink_get_caps() does
not set any supported_interfaces flags.
Instead of a cmode, on 88E6250 we have a read-only port mode value that
encodes similar information. There is no reason to bother mapping port
mode to the cmodes of other switch models; instead we introduce a
mv88e6250_setup_supported_interfaces() that is called directly from
mv88e6250_phylink_get_caps().

commit 2f4a4d63a1 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

A recent change to cxl_mem_get_records_log() [1] highlighted a subtle
nuance of looping calls to cxl_internal_send_cmd(), i.e. that
cxl_internal_send_cmd() modifies the 'size_out' member of the @mbox_cmd
argument. That mechanism is useful for communicating underflow, but it
is unwanted when reusing @mbox_cmd for a subsequent submission. It turns
out that cxl_xfer_log() avoids this scenario by always redefining
@mbox_cmd each iteration.
Update cxl_mem_get_records_log() and cxl_mem_get_poison() to follow the
same style as cxl_xfer_log(), i.e. re-define @mbox_cmd each iteration.
The cxl_mem_get_records_log() change is just a style fixup, but the
cxl_mem_get_poison() change is a potential fix, per Alison [2]:
Poison list retrieval can hit this case if the MORE flag is set and
a follow on read of the list delivers more records than the previous
read. ie. device gives one record, sets the _MORE flag, then gives 5.
Not an urgent fix since this behavior has not been seen in the wild,
but worth tracking as a fix.

It was possible to have pick_eevdf() return NULL, which then causes a
NULL-deref. This turned out to be due to entity_eligible() returning
falsely negative because of a s64 multiplcation overflow.
Specifically, reweight_eevdf() computes the vlag without considering
the limit placed upon vlag as update_entity_lag() does, and then the
scaling multiplication (remember that weight is 20bit fixed point) can
overflow. This then leads to the new vruntime being weird which then
causes the above entity_eligible() to go side-ways and claim nothing
is eligible.
Thus limit the range of vlag accordingly.
All this was quite rare, but fatal when it does happen.

discard_new_inode() is the wrong interface to use when we need to free
an inode that was never inserted into the inode hash table; we can
bypass the whole iput() -> evict() path and replace it with
__destroy_inode(); kmem_cache_free() - this fixes a WARN_ON() about
I_NEW.

bch2_journal_write() was incorrectly waiting on earlier journal writes
synchronously; this usually worked because most of the time we'd be
running in the context of a thread that did a journal_buf_put(), but
sometimes we'd be running out of the same workqueue that completes those
prior journal writes.
Additionally, this makes sure to punt to a workqueue before submitting
preflushes - we really don't want to be calling submit_bio() in the main
transaction commit path.

Freeing key cache items is a multi stage process; we need to wait for an
SRCU grace period to elapse, and we handle this ourselves - partially to
avoid callback overhead, but primarily so that when allocating we can
first allocate from the freed items waiting for an SRCU grace period.
Previously, the shrinker was counting the items on the 'waiting for SRCU
grace period' lists as items being scanned, but this meant that too many
items waiting for an SRCU grace period could prevent it from doing any
work at all.
After this, we're seeing that items skipped due to the accessed bit are
the main cause of the shrinker not making any progress, and we actually
want the key cache shrinker to run quite aggressively because reclaimed
items will still generally be found (more compactly) in the btree node
cache - so we also tweak the shrinker to not count those against
nr_to_scan.

this stores the SRCU sequence number, which we use to check if an SRCU
barrier has elapsed; this is a partial fix for the key cache shrinker
not actually freeing.

- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks because
the clk provider device is repeatedly runtime PM resumed and
suspended during probe and clk registration. Resuming the clk
provider device deadlocks with an ABBA deadlock due to genpd_lock and
the clk prepare_lock. The fix is to keep the device runtime resumed
while registering clks.
- Another runtime PM related deadlock, this time with disabling unused
clks during late init. We get an ABBA deadlock where a device is
runtime PM resuming (or suspending) while the disabling of unused
clks is happening in parallel. That runtime PM action calls into the
clk framework and tries to grab the clk prepare_lock while the
disabling of unused clks holds the prepare_lock and is waiting for
that runtime PM action to complete. The fix is to runtime resume all
the clk provider devices before grabbing the clk prepare_lock during
disable unused.
- A build fix to provide an empty devm_clk_rate_exclusive_get()
function when CONFIG_COMMON_CLK=n

Performance regression reported with NFS/RDMA using Omnipath,
bisected to commit e084ee673c ("svcrdma: Add Write chunk WRs to
the RPC's Send WR chain").
Tracing on the server reports:
nfsd-7771 [060] 1758.891809: svcrdma_sq_post_err:
cq.id=205 cid=226 sc_sq_avail=13643/851 status=-12
sq_post_err reports ENOMEM, and the rdma->sc_sq_avail (13643) is
larger than rdma->sc_sq_depth (851). The number of available Send
Queue entries is always supposed to be smaller than the Send Queue
depth. That seems like a Send Queue accounting bug in svcrdma.
As it's getting to be late in the 6.9-rc cycle, revert this commit.
It can be revisited in a subsequent kernel release.

Fix a missing bounds check in superblock validation.
Note that we don't yet have repair code for this case - repair code for
individual items is generally low priority, since the whole superblock
is checksummed, validated prior to write, and we have backups.

====================
mlxsw: Fixes
This patchset fixes the following issues:
- During driver de-initialization the driver unregisters the EMAD
response trap by setting its action to DISCARD. However the manual
only permits TRAP and FORWARD, and future firmware versions will
enforce this.
In patch #1, suppress the error message by aligning the driver to the
manual and use a FORWARD (NOP) action when unregistering the trap.
- The driver queries the Management Capabilities Mask (MCAM) register
during initialization to understand if certain features are supported.
However, not all firmware versions support this register, leading to
the driver failing to load.
Patches #2 and #3 fix this issue by treating an error in the register
query as an indication that the feature is not supported.
v2:
- Patch #2:
- Make mlxsw_env_max_module_eeprom_len_query() void
