  more standards conformant and the ibmvfc one is to fix a user visible

      ALSA: memalloc: Try dma_alloc_noncontiguous() at first · 9d8e536d
      Takashi Iwai authored 
      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.

      Pull ata fixes from Damien Le Moal:
 "Several libata generic code fixes for rc5:

   - Add missing translation of the SYNCHRONIZE CACHE 16 scsi command as
     this command is mandatory for host-managed ZBC drives.

     The lack of support for it in libata-scsi was causing issues with
     some passthrough applications using ZBC drives (from Shin'ichiro).

   - Fix the error path of libata-transport host, port, link and device
     attributes initialization (from Yingliang).

   - Prevent issuing new commands to a drive that is in the NCQ error
     state and undergoing recovery (From Niklas).

     This bug went unnoticed for a long time as commands issued to a
     drive in error state are aborted immediately and retried by the
     scsi layer, hiding the useless abort-and-retry sequence"

      Linus Torvalds authored 
      Pull arm64 fixes from Catalin Marinas:

 - Another fix for rodata=full. Since rodata= is not a simple boolean on
   arm64 (accepting 'full' as well), it got inadvertently broken by
   changes in the core code. If rodata=on is the default and rodata=off
   is passed on the kernel command line, rodata_full is never disabled

 - Fix gcc compiler warning of shifting 0xc0 into bits 31:24 without an
   explicit conversion to u32 (triggered by the AMPERE1 MIDR definition)

 - Include asm/ptrace.h in asm/syscall_wrapper.h to fix an incomplete
   struct pt_regs type causing the BPF verifier to refuse to load a
   tracing program which accesses pt_regs

      ata: libata-core: do not issue non-internal commands once EH is pending · e20e81a2
      Niklas Cassel authored 
      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.)

Fixes: e494f6a7 ("[SCSI] improved eh timeout handler")
