This patch fixes a hang that can occur in ATA EH with ipr. With ipr's
usage of libata, commands should never end up on ap->eh_done_q. The
timeout function we use for ipr, even for SATA devices, is
scsi_times_out, so ATA_QCFLAG_EH_SCHEDULED never gets set for ipr and EH
is driven completely by ipr and SCSI. The SCSI EH thread ends up calling
ipr's eh_device_reset_handler, which then calls
ata_std_error_handler. This ends up calling ipr_sata_reset, which issues
a reset to the device. This should result in all pending commands
getting failed back and having ata_qc_complete called for them, which
should end up clearing ATA_QCFLAG_FAILED as qc->flags gets zeroed in
ata_qc_free. This ensures that when we end up in ata_eh_finish, we
don't do anything more with the command.
On adapters that only support a single interrupt and when running with
two MSI-X vectors or less, the adapter firmware guarantees that
responses to all outstanding commands are sent back prior to sending the
response to the SATA reset command. On newer adapters supporting
multiple HRRQs, however, this can no longer be guaranteed, since the
command responses and reset response may be processed on different
HRRQs.
If ipr returns from ipr_sata_reset before the outstanding command was
returned, this sends us down the path of __ata_eh_qc_complete which then
moves the associated scsi_cmd from the work_q in
scsi_eh_bus_device_reset to ap->eh_done_q, which then will sit there
forever and we will be wedged.
This patch fixes this up by ensuring that any outstanding commands are
flushed before returning from eh_device_reset_handler for a SATA device.

This patch closes up some potential race conditions observed in the
error handling paths in ipr while debugging an issue resulting in a hang

correct lock when adding and removing commands from the free and pending
queues in some error scenarios.

This fixes a race condition in the error handlomg paths of ipr. While a
command is outstanding to the adapter, it is placed on a pending queue
for the hrrq it is associated with, while holding the HRRQ lock. When a
command is completed, it is removed from the pending queue, under HRRQ
lock, and placed on a local list. This list is then iterated through
without any locks and each command's done function is invoked, inside of
which, the command gets returned to the free list while grabbing the
HRRQ lock. This fixes two race conditions when commands have been
removed from the pending list but have not yet been added to the free
list. Both of these changes fix race conditions that could result in
returning success from eh_abort_handler and then later calling scsi_done
for the same request.
The first race condition is in ipr_cancel_op. It looks through each
pending queue to see if the command to be aborted is still outstanding
or not. Rather than looking on the pending queue, reverse the logic to
check to look for commands that are NOT on the free queue. The second
race condition can occur when in ipr_wait_for_ops where we are waiting
for responses for commands we've aborted.

When an SMP task timeouts, it will call lldd_abort_task to release the
associated slot, and then will release the sas_task.
Currently in lldd_abort_task, if we fail to internally abort IO, then
the slot of SMP IO is not released, but sas_task will still be later
released, so the slot's sas_task is NULL, which will cause NULL pointer
when hisi_sas_slot_task_free happens later.
To resolve, check the return value of internal abort, and release the
slot if it failed.

There are some rules to decide which error code has the high priority
when errors happen together:
(1) Error phase of CQ decides the error happens on RX or TX;
(2) For TX error, when DMA/TRANS TX error happen simultaneously, the
priority of DMA TX error is higher than TRANS TX error, so for the
priority of TX error: DW2 (DMA TX part) > DW0;
(3) For RX error, when TRANS/DMA/SIPC RX error happen simultaneously,
the priority of TRANS RX error is higher than DMA and SIPC RX error,
and we should also keep the rules (the priority of DW3 > DW2), so
for the priority of RX error: DW1 > DW3 > DW2(SIPC RX part);
(4) There are also a priority we should keep in the same error type.
So, modify slot error code to handle this.
