With CONFIG_SLUB=y, following commit 6edf2576 ("mm/slub: enable
debugging memory wasting of kmalloc") mt7621 failed to boot very early,
without showing any console messages.
This exposed the pre-existing bug of mt7621.c using kzalloc before normal
memory management was available.
Prior to this slub change, there existed the unintended protection against
"kmem_cache *s" being NULL as slab_pre_alloc_hook() happened to
return NULL and bailed out of slab_alloc_node().
This allowed mt7621 prom_soc_init to fail in the soc_dev_init kzalloc,
but continue booting without the SOC_BUS driver device registered.

Console output from a DEBUG_ZBOOT vmlinuz kernel loading,
with mm/slub modified to warn on kmem_cache zero or null:

The latest fix for the non-contiguous memalloc helper changed the
allocation method for a non-IOMMU system to use only the fallback
allocator.  This should have worked, but it caused a problem sometimes
when too many non-contiguous pages are allocated that can't be treated
by HD-audio controller.

As a quirk workaround, go back to the original strategy: use
dma_alloc_noncontiguous() at first, and apply the fallback only when
it fails, but only for non-IOMMU case.

We'll need a better fix in the fallback code as well, but this
workaround should paper over most cases.

While the ATA specification states that a device should return command
aborted for all commands queued after the device has entered error state,
since ATA only keeps the sense data for the latest command (in non-NCQ
case), we really don't want to send block layer commands to the device
after it has entered error state. (Only ATA EH commands should be sent,
to read the sense data etc.)

Currently, scsi_queue_rq() will check if scsi_host_in_recovery()
(state is SHOST_RECOVERY), and if so, it will _not_ issue a command via:
scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd())
-> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue()

Before commit e494f6a7 ("[SCSI] improved eh timeout handler"),
when receiving a TFES error IRQ, the call chain looked like this:
ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort() ->
ata_qc_complete() -> ata_qc_schedule_eh() -> blk_abort_request() ->
blk_rq_timed_out() -> q->rq_timed_out_fn() (scsi_times_out()) ->
scsi_eh_scmd_add() -> scsi_host_set_state(shost, SHOST_RECOVERY)

Which meant that as soon as an error IRQ was serviced, SHOST_RECOVERY
would be set.

However, after commit e494f6a7 ("[SCSI] improved eh timeout handler"),
scsi_times_out() will instead call scsi_abort_command() which will queue
delayed work, and the worker function scmd_eh_abort_handler() will call
scsi_eh_scmd_add(), which calls scsi_host_set_state(shost, SHOST_RECOVERY).

So now, after the TFES error IRQ has been serviced, we need to wait for
the SCSI workqueue to run its work before SHOST_RECOVERY gets set.

It is worth noting that, even before commit e494f6a7 ("[SCSI] improved
eh timeout handler"), we could receive an error IRQ from the time when
scsi_queue_rq() checks scsi_host_in_recovery(), to the time when
ata_scsi_queuecmd() is actually called.

In order to handle both the delayed setting of SHOST_RECOVERY and the
window where we can receive an error IRQ, add a check against
ATA_PFLAG_EH_PENDING (which gets set when servicing the error IRQ),
inside ata_scsi_queuecmd() itself, while holding the ap->lock.
(Since the ap->lock is held while servicing IRQs.)

   KASAN into the current kernel config

 - binutils commit 906f69cf65da ("IBM zSystems: Issue error for *DBL
   relocs on misaligned symbols") caused several link errors. Always
   build relocatable kernel to avoid this problem

 - raise the minimum clang version to 15.0.0 to avoid silent generation
   of a corrupted code

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix 'perf stat' crash with --per-node --metric-only in CSV mode, due
   to the AGGR_NODE slot in the 'aggr_header_csv' array not being set.

 - Fix printing prefix in CSV output of 'perf stat' metrics in interval
   mode (-I), where an extra separator was being added to the start of
   some lines.

 - Fix skipping branch stack sampling 'perf test' entry, that was using
   both --branch-any and --branch-filter, which can't be used together.

Pull RISC-V fixes from Palmer Dabbelt:

 - A fix to add the missing PWM LEDs into the SiFive HiFive Unleashed
   device tree.

 - A fix to fully clear a task's registers on creation, as they end up
   in userspace and thus leak kernel memory.

 - A pair of VDSO-related build fixes that manifest on recent LLVM-based
   toolchains.

 - A fix to our early init to ensure the DT is adequately processed
   before reserved memory nodes are processed.

 "This is a pretty large diffstat for this time of the release. The main
  culprit is a reorganization of the AMD assembly trampoline, allowing
  percpu variables to be accessed early.

  This is needed for the return stack depth tracking retbleed mitigation
  that will be in 6.2, but it also makes it possible to tighten the IBRS
  restore on vmexit. The latter change is a long tail of the
  spectrev2/retbleed patches (the corresponding Intel change was simpler
  and went in already last June), which is why I am including it right
  now instead of sharing a topic branch with tip.

  Being assembly and being rich in comments makes the line count balloon
  a bit, but I am pretty confident in the change (famous last words)
  because the reorganization actually makes everything simpler and more
  understandable than before. It has also had external review and has
  been tested on the aforementioned 6.2 changes, which explode quite
  brutally without the fix.

  Apart from this, things are pretty normal.

   - PCI fix

   - PV clock fix

   - Fix clash between PMU MSRs and other MSRs

   - Prepare SVM assembly trampoline for 6.2 retbleed mitigation and
