perf: riscv legacy: fix kerneldoc comment warning
riscv: Ensure isa-ext static keys are writable
Currently, in virtio_scsi, if 'bd->last' is not set to true while
dispatching request, such io will stay in driver's queue, and driver
will wait for block layer to dispatch more rqs. However, if block
layer failed to dispatch more rq, it should trigger commit_rqs to
inform driver.
There is a problem in blk_mq_try_issue_list_directly() that commit_rqs
won't be called:
// assume that queue_depth is set to 1, list contains two rq
blk_mq_try_issue_list_directly
blk_mq_request_issue_directly
// dispatch first rq
// last is false
__blk_mq_try_issue_directly
blk_mq_get_dispatch_budget
// succeed to get first budget
__blk_mq_issue_directly
scsi_queue_rq
cmd->flags |= SCMD_LAST
virtscsi_queuecommand
kick = (sc->flags & SCMD_LAST) != 0
// kick is false, first rq won't issue to disk
queued++
blk_mq_request_issue_directly
// dispatch second rq
__blk_mq_try_issue_directly
blk_mq_get_dispatch_budget
// failed to get second budget
ret == BLK_STS_RESOURCE
blk_mq_request_bypass_insert
// errors is still 0
if (!list_empty(list) || errors && ...)
// won't pass, commit_rqs won't be called
In this situation, first rq relied on second rq to dispatch, while
second rq relied on first rq to complete, thus they will both hung.
Fix the problem by also treat 'BLK_STS_*RESOURCE' as 'errors' since
it means that request is not queued successfully.
Same problem exists in blk_mq_dispatch_rq_list(), 'BLK_STS_*RESOURCE'
can't be treated as 'errors' here, fix the problem by calling
commit_rqs if queue_rq return 'BLK_STS_*RESOURCE'.

The recent kernel added lost count can be read from either read(2) or
ring buffer data with PERF_SAMPLE_READ. As it's a variable length data
we need to access it according to the format info.
But for perf tools use cases, PERF_FORMAT_ID is always set. So we can
only check PERF_FORMAT_LOST bit to determine the data format.
Add sample_read_value_size() and next_sample_read_value() helpers to
make it a bit easier to access. Use them in all places where it reads
the struct sample_read_value.

The perf_counts_values should be increased to read the new lost data.
Also adjust values after read according the read format.
This supports PERF_FORMAT_GROUP which has a different data format but
it's only available for leader events. Currently it doesn't have an API
to read sibling (member) events in the group. But users may read the
sibling event directly.
Also reading from mmap would be disabled when the read format has ID or
LOST bit as it's not exposed via mmap.

Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

A mask encoding of a cpu map is laid out as:
u16 nr
u16 long_size
unsigned long mask[];
However, the mask may be 8-byte aligned meaning there is a 4-byte pad
after long_size. This means 32-bit and 64-bit builds see the mask as
being at different offsets. On top of this the structure is in the byte
data[] encoded as:
u16 type
char data[]
This means the mask's struct isn't the required 4 or 8 byte aligned, but
is offset by 2. Consequently the long reads and writes are causing
undefined behavior as the alignment is broken.
Fix the mask struct by creating explicit 32 and 64-bit variants, use a
union to avoid data[] and casts; the struct must be packed so the
layout matches the existing perf.data layout. Taking an address of a
member of a packed struct breaks alignment so pass the packed
perf_record_cpu_map_data to functions, so they can access variables with
the right alignment.
As the 64-bit version has 4 bytes of padding, optimizing writing to only
write the 32-bit version.
Committer notes:
Disable warnings about 'packed' that break the build in some arches like
riscv64, but just around that specific struct.

With the existing code in store_latency_data(), the memory operation (mem_op)
returned to the user is always OP_LOAD where in fact, it should be OP_STORE.
This comes from the fact that the function is simply grabbing the information
from a data source map which covers only load accesses. Intel 12th gen CPU
offers precise store sampling that captures both the data source and latency.
Therefore it can use the data source mapping table but must override the
memory operation to reflect stores instead of loads.
