[SCSI] hpsa: Allow multiple command completions per interrupt.
This is done by adding support for the so-called "performant mode"
(that's really what they called it). Smart Array controllers
have a mode which enables multiple command completions to be
delivered with a single interrupt, "performant" mode. We want to use
that mode, as some newer controllers will be requiring this mode.

Added new callbacks phy_enable and set_phy_speed in the

Current implementation only supports direct attached phys, but we

this wrapper function used to send request to controller firmware to modify

a function for easly obtaining the local phy object for direct attached.

The mpt2sas driver wants to use transport layer retries (TLR) so the

[SCSI] lpfc: restore MSI-X/MSI support
A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts.
This patch restores lpfc's ability to support MSI-X/MSI interrupts that the
"Addition of SLI4 Interface - Base Support" patch [2] broke.
It reestablishes MSI-X as the default interrupt method and in case MSI-X is not
supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx.

[2]: commit
da0436e915a5c17ee79e72c1bf978a4ebb1cbf4d
[James Smart:
Background:
Nothing Broke. This was intended.
We had originally enabled MSI-X by default, but in qualification within the
last 12 months, we encountered a major catch-22:
There were at least 4 platforms, from 2 major OEMs, that :
- Say they support MSI-X - platform routines work and act as if they do.
- We enable it, generate a test interrupt to check they really do deliver it,
and it works.
- But shortly after attachment, the system hangs or loses interrupts,
resulting in a bad system behavior.
Given the distro's picking up the 2.6.32 kernel, we had to stick with a
default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get
fixed.
However, we're also now encountering platforms that require MSI-X and never
INTx, so we must change. It's desired also for also for performance reasons.
So - now (2.6.33) is the right time to re-enable MSI-X by default.

This failure happens when esp_reconnect_with_tag() tries to read in two

[SCSI] scsi_transport_fc: Remove capping from dev_loss_tmo
Currently dev_loss_tmo is capped by SCSI_DEVICE_BLOCK_MAX_TIMEOUT.
This causes problem with multipathing when the 'no_path_retry' setting
exceeds the dev_loss_tmo setting, as then the system might run into
a deadlock when all paths have been removed temporarily for longer
than dev_loss_tmo.
The principal reasons for the capping has been that we should
not allow a remote port to remain in status 'blocked' indefinitely,
so the capping is there to ensure that the port status is being reset
eventually.
However, the fast_io_fail_tmo will also move the remote port out of
the 'blocked' state, so for any HBA driver implementing both the
capping should really be on the fast_io_fail_tmo, and not on the
dev_loss_tmo.
This patch implements just that, ie the fast_io_fail_tmo is capped
to SCSI_DEVICE_BLOCK_TIMEOUT and the capping is removed from
dev_loss_tmo when fast_io_fail_tmo is set.
This allows us to synchronize the dev_loss_tmo setting to the
'no_path_retry' setting from multipathing thus avoiding the deadlock.

[SCSI] fc-transport: Use packed modifier for fc_bsg_request structure.
The 32bit kernel does not add padding bytes in the fc_bsg_request structure
whereas the 64bit kernel adds padding bytes in the fc_bsg_request structure.
Due to this, structure elements gets mismatched with 32bit application and
64bit kernel.To resolve this, used packed modifier to avoid adding padding bytes.
