23dc04f1ec [SCSI] lpfc 8.1.1 : Adjust use of scsi_block_requests and interaction w/ FC transport
- Remove unnecessary scsi_block_requests calls on rport deletes.
  This was deadlocking the sdev removals as they wanted to flush commands.
- No longer block requests when adding the remote port (to block
  discovery). Instead, register, then change port role. Maps to Qlogic
  behavior, and closer to the register-node-upon-first-ELS behavior.

6281bfe000 [SCSI] lpfc 8.1.1 : Fixes for short cable pulls
Cause: Link bounces were causing discovery ELS's to be killed.
Driver was not properly flushing ELS commands upon the subsequent

ce155ccecd [SCSI] ipr: Driver initialization fix for kexec/kdump
When kexec booting a kernel when the previous kernel did not
call ipr's shutdown method, the ipr adapter does not get
properly initialized, which can result in the ipr adapter
completing commands issued by the previous kernel. Fix ipr
to detect this scenario by reading the adapter's interrupt
mask register and the microprocessor interrupt register.
If the interrupt mask register indicates that interrupts
are enabled or the reset alert bit is set when the card is
probed, this means the card is in an unknown state and we
hard reset the card.

50630195bb [libata] mark certain hardware (or drivers) with a no-atapi flag
Some hardware does not support the PACKET command at all.
Other hardware supports ATAPI, but the driver does something nasty such
as calling BUG() when an ATAPI command is issued.

For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI.

a2a7a662f8 [PATCH] libata: implement ata_exec_internal()
This patch implements ata_exec_internal() function which performs
libata internal command execution.  Previously, this was done by each
user by manually initializing a qc, issueing it, waiting for its
completion and handling errors.  In addition to obvious code
factoring, using ata_exec_internal() fixes the following bugs.

* qc not freed on issue failure
* ap->qactive clearing could race with the next internal command
* race between timeout handling and irq
* ignoring error condition not represented in tf->status

Also, qc & hardware are not accessed anymore once it's completed,
making internal commands more conformant with general semantics.
ata_exec_internal() also makes it easy to issue internal commands from
multiple threads if that becomes necessary.

This patch only implements ata_exec_internal().  A following patch
will convert all users.

Jeff, all patches have been regenerated against upstream branch as of
today.  (575ab52a21)

Also, I took out a debug printk from ata_exec_internal (don't know how
that one got left there).  Other than that, all patches are identical
to the previous posting.
