During controller reset, the driver tries to flush all the pending firmware
event works from worker queue that are queued prior to the reset. However,
if any work is waiting for device addition/removal operation to be
completed at the SML, then a deadlock is observed. This is due to the
controller reset waiting for the device addition/removal to be completed
and the device/addition removal is waiting for the controller reset to be
completed.
To limit this deadlock, continue with the controller reset handling without
canceling the work which is waiting for device addition/removal operation
to complete at SML.

Commit 7d2b5dd0bc ("sched/numa: Allow a floating imbalance between NUMA
nodes") allowed an imbalance between NUMA nodes such that communicating
tasks would not be pulled apart by the load balancer. This works fine when
there is a 1:1 relationship between LLC and node but can be suboptimal
for multiple LLCs if independent tasks prematurely use CPUs sharing cache.
Zen* has multiple LLCs per node with local memory channels and due to
the allowed imbalance, it's far harder to tune some workloads to run
optimally than it is on hardware that has 1 LLC per node. This patch
allows an imbalance to exist up to the point where LLCs should be balanced
between nodes.
On a Zen3 machine running STREAM parallelised with OMP to have on instance
per LLC the results and without binding, the results are

There are inconsistencies when determining if a NUMA imbalance is allowed
that should be corrected.
o allow_numa_imbalance changes types and is not always examining
the destination group so both the type should be corrected as
well as the naming.
o find_idlest_group uses the sched_domain's weight instead of the
group weight which is different to find_busiest_group
o find_busiest_group uses the source group instead of the destination
which is different to task_numa_find_cpu
o Both find_idlest_group and find_busiest_group should account
for the number of running tasks if a move was allowed to be
consistent with task_numa_find_cpu

If backing file's filesystem has implemented ->fallocate(), we think the
loop device can support discard, then pass sb->s_blocksize as
discard_granularity. However, some underlying FS, such as overlayfs,
doesn't set sb->s_blocksize, and causes discard_granularity to be set as
zero, then the warning in __blkdev_issue_discard() is triggered.
Christoph suggested to pass kstatfs.f_bsize as discard granularity, and
this way is fine because kstatfs.f_bsize means 'Optimal transfer block
size', which still matches with definition of discard granularity.
So fix the issue by setting discard_granularity as kstatfs.f_bsize if it
is available, otherwise claims discard isn't supported.

In the queue path, move around when we assign sas_task->lldd_task such that
this pointer and the SAS_TASK_AT_INITIATOR flag are set atomically. It is
also not required to clear SAS_TASK_AT_INITIATOR in isci_task_execute_task()
error path as it is also cleared immediately after in isci_task_refuse()
call.
Now the following items may be considered:
- SAS_TASK_STATE_DONE and SAS_TASK_AT_INITIATOR are mutually exclusive
apart from possibly when SAS_TASK_STATE_DONE is set in
sas_scsi_find_task(), but that is after .lldd_abort_task, i.e. the
considered callback, is called.
- If isci_task_refuse() is called in the queue path, then
sas_task->lldd_task and SAS_TASK_AT_INITIATOR are cleared atomically in
isci_task_refuse().
- In the completion path, SAS_TASK_STATE_DONE is set and
SAS_TASK_AT_INITIATOR is cleared atomically before the
sas_task.lldd_task is cleared later.
So in isci_task_abort_task() if SAS_TASK_STATE_DONE is not set and
sas_task.lldd_task is still set, then SAS_TASK_AT_INITIATOR must be set -
so we can drop this check on SAS_TASK_AT_INITIATOR.

The TH_LOG() macro is an optional debug logging function made
available by kselftest itself. When TH_LOG_ENABLED is set it
prints the provided message with additional information and
formatting that already includes a newline.
Providing a newline to the message printed by TH_LOG() results
in a double newline that produces irregular test output.
Remove the unnecessary newlines from the text provided to
TH_LOG().

In support of debugging the SGX tests print details from
the enclave and its memory mappings if any failure is encountered
during enclave loading.
When a failure is encountered no data is printed because the
printing of the data is preceded by cleanup of the data.
Move the data cleanup after the data print.

It is not possible to build an enclave if it was not possible to load
the binary from which it should be constructed. Do not attempt
to make further progress but instead return with failure. A
"return false" from setup_test_encl() is expected to trip an
ASSERT_TRUE() and abort the rest of the test.

== Background ==
The SGX selftests track parts of the enclave binaries in an array:
encl->segment_tbl[]. That array is dynamically allocated early
(but not first) in the test's lifetime. The array is referenced
at the end of the test in encl_delete().
== Problem ==
encl->segment_tbl[] can be NULL if the test fails before its
allocation. That leads to a NULL-pointer-dereference in encl_delete().
This is triggered during early failures of the selftest like if the
enclave binary ("test_encl.elf") is deleted.
== Solution ==
Ensure encl->segment_tbl[] is valid before attempting to access
its members. The offset with which it is accessed, encl->nr_segments,
is initialized before encl->segment_tbl[] and thus considered valid
to use after the encl->segment_tbl[] check succeeds.

The qla_sess_op_cmd_list was introduced in commit 8b2f5ff3d0 ("qla2xxx:
cleanup cmd in qla workqueue before processing TMR"). Then the usage of
this list was dropped in commit fb35265b12 ("scsi: qla2xxx: Remove
session creation redundant code").
Thus, remove this list since it is no longer used.

The new YAML device tree bindings gives new and proper names
to several of the AB850[05] nodes and redefines the way we
use numbering on PWMs to use reg.
Update all the DTS nodes accordingly.

Drop the debugfs nodes because these are not real devices.
