d68cd75992 [SCSI] sym53c8xx: PCI Error Recovery support
This patch adds the PCI error recovery callbacks to the Symbios SCSI device
driver.  It includes support for First Failure Data Capture.

Signed-off-by: Linas Vepstas <linas@austin.ibm.com>

Assorted changes to initial patches, including returning IRQ_NONE from the
interrupt handler if the device is offline and re-using the eh_done completion
in the scsi error handler.

2ba6536772 [SCSI] sym53c8xx: Stop overriding scsi_done
Instead of telling the reset routine that the command completed from
sym_eh_done, do it from sym_xpt_done.  The 'to_do' element of the ucmd
is redundant -- it serves only to tell whether eh_done is valid or not,
and we can tell this by checking to see if it's NULL.

39c05d1e3c [SCSI] sym53c8xx: Remove data_mapping and data_mapped
Before all commands used sg, data_mapping and data_mapped were used to
distinguish whether the command had used map_single or map_sg.  Now all
commands are sg, so we can delete data_mapping, data_mapped and the
wrapper functions __unmap_scsi_data, __map_scsi_sg_data, unmap_scsi_data
and map_scsi_sg_data.

20d2d3afa8 [SCSI] qla1280: eliminate wasted space in request and response ring
i think there is wasted space in allocated pages for request and
response rings.  The allocations are made with REQUEST_ENTRY_CNT + 1
and RESPONSE_ENTRY_CNT + 1, but they are set with 256 and 16.

So we got more pages, which we dont use very much so eliminate them.

1c3f0b8e07 Change struct marker users
Prior to use struct marker in the linux kernel markers, we need to clean
two drivers which use this structure name.

Change bonding driver types :
- struct marker to struct bond_marker.
- marker_t to bond_marker_t.
- marker_header to bond_marker_header.
- marker_header_t to bond_marker_header_t.

Change qla4xxx struct marker_entry usage :
- Change struct marker_entry for struct qla4_marker_entry.

ba25f9dcc4 Use helpers to obtain task pid in printks
The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

3be6cbd73f [libata] kill ata_sg_is_last()
Short term, this works around a bug introduced by early sg-chaining
work.

Long term, removing this function eliminates a branch from a hot
path loop in each scatter/gather table build.  Also, as this code
demonstrates, we don't need to _track_ the end of the s/g list, as
long as we mark it in some way.  And doing so programatically is nice.
So its a useful cleanup, regardless of its short term effects.

Based conceptually on a quick patch by Jens Axboe.

9cb83c7529 [SCSI] add use_sg_chaining option to scsi_host_template
This option is true if a low-level driver can support sg
chaining. This will be removed eventually when all the drivers are
converted to support sg chaining. q->max_phys_segments is set to
SCSI_MAX_SG_SEGMENTS if false.
