This patch fix for sata IO circular lock dependency. When we call task_done
for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will
get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we
should drop pm8001_ha->lock when we call task_done for SATA task.

This issue was discovered during 10G iscsi testing
Default value of 'sq_size' module parameter is '0' which means driver
should use predefined SQ queue size when setting up iscsi connection.

After commits c82f63e411 (PCI: check saved
state before restore) and 4b77b0a2ba (PCI:
Clear saved_state after the state has been restored) PCI drivers are
prevented from restoring the device standard configuration registers
twice in a row. These changes introduced a regression on ipr EEH
recovery.
The ipr device driver saves the PCI state only during the device probe
and restores it on ipr_reset_restore_cfg_space() during IOA resets. This
behavior is causing the EEH recovery to fail after the second error
detected, since the registers are not being restored.
One possible solution would be saving the registers after restoring
them. The problem with this approach is that while recovering from an
EEH error if pci_save_state() results in an EEH error, the adapter/slot
will be reset, and end up back in ipr_reset_restore_cfg_space(), but it
won't have a valid saved state to restore, so pci_restore_state() will
fail.
The following patch introduces a workaround for this problem, hacking
around the PCI API by setting pdev->state_saved = true before we do the
restore. It fixes the EEH regression and prevents that we hit another
EEH error during EEH recovery.

This patch moves the setting of the init_done (and online) flag to

So libosd has decided to sacrifice some code simplicity for the sake of
a clean API. One of these things is the possibility for users to call
osd_end_request, in any condition at any state. This opens up some
problems with calling blk_put_request when out-side of the completion
callback but calling __blk_put_request when detecting a from-completion
state.
The current hack was working just fine until exofs decided to operate on
all devices in parallel and wait for the sum of the requests, before
deallocating all osd-requests at once. There are two new possible cases
1. All request in a group are deallocated as part of the last request's
async-done, request_queue is locked.
2. All request in a group where executed asynchronously, but
de-allocation was delayed to after the async-done, in the context of
another thread. Async execution but request_queue is not locked.
The solution I chose was to separate the deallocation of the osd_request
which has the information users need, from the deallocation of the
internal(2) requests which impose the locking problem. The internal
block-requests are freed unconditionally inside the async-done-callback,
when we know the queue is always locked. If at osd_end_request time we
still have a bock-request, then we know it did not come from within an
async-done-callback and we can call the regular blk_put_request.
The internal requests were used for carrying error information after
execution. This information is now copied to osd_request members for
later analysis by user code.
The external API and behaviour was unchanged, except now it really
supports what was previously advertised.

On the large servers, I/O port resource may not be assigned to all
the PCI devices since it is limited (to 64KB on Intel Architecture[1])
and it may also be fragmented (I/O base register of PCI-to-PCI bridge
will usually be aligned to a 4KB boundary[2]).
If no I/O port resource is assigned to devices, those devices do not
work.
[1] Some machines support 64KB I/O port space per PCI segment.
[2] Some P2P bridges support optional 1KB aligned I/O base.
Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy
I/O port free. I have also tested the patch and it had no problem.
The way to make PCI legacy I/O port free is the same as Fusion-MPT
driver's and it has been merged into 2.6.30.4.
This has already been fixed in e1000 and lpfc.
As a result of the above, the driver can handle its device even when
there are a huge number of PCI devices being used on the system and no
I/O port region assigned to the device.

dio transfer always resets mdata->page_order to zero. It breaks
high-order pages previously allocated for non-dio transfer.
This patches adds reserved_page_order to st_buffer structure to save
page order for non-dio transfer.
http://bugzilla.kernel.org/show_bug.cgi?id=14563
When enlarge_buffer() allocates 524288 from 0, st uses six-order page
allocation. So mdata->page_order is 6 and frp_seg is 2.
After that, if st uses dio, sgl_map_user_pages() sets
mdata->page_order to 0 for st_do_scsi(). After that, when we call
normalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096)
though we should free frp_seg * PAGE_SIZE << 6 (2 * 4096 << 6). So we
see buffer_size is set to 516096 (524288 - 8192).
