scsi: mpt3sas: Fix for incorrect numbers for MSIX vectors enabled when non RDPQ card is enumerated first.
No. of MSIX vectors supported = min (Total no. of CPU cores,
MSIX vectors supported by card)
when RDPQ is disabled "max_msix_vectors" module parameter which was
declared as global was set to '8' and hence if there are more than one card
in system among which if RDPQ disabled card is enumerated first then only 8
MSIX vectors was getting enabled for all the cards(including RDPQ enabled
card,which can support more than 8 MSIX vectors).
Used local variable instead of global variable ,if RDPQ is disabled this
local variable is set to '8' else it is set to "max_msix_vectors" (by
default this is set to -1, whose value can be set by user during driver
load time).So now regardless of whether RDPQ disabled card is enumerated
first or RDPQ enabled card is enumerated first , MSIX vectors enabled
depends on the cards capability.

scsi: advansys: fix build warning for PCI=n
The advansys probe function tries to handle both ISA and PCI cases, each
hidden in an #ifdef when unused. This leads to a warning indicating that
when PCI is disabled we could be using uninitialized data:
drivers/scsi/advansys.c: In function advansys_board_found :
drivers/scsi/advansys.c:11036:5: error: ret may be used uninitialized in this function [-Werror=maybe-uninitialized]

This cannot happen in practice because the hardware in question only

for consistency and avoids the warning.

The ungate work turns on the clock before it exits hibern8, if the link

This revert came about because of efforts by Ewan Milne, Curtis Taylor
and I. In researching this issue, significant performance issues were
seen on large CPU count systems using the software FCOE stack. Hannes
also weighed in.
The same was not apparent on much smaller low count CPU systems. The
behavior introduced by commit 3e22760d4db6fd89e0be46c3d132390a251da9c6
lands sup with large count CPU systems seeing continual
blk_requeue_request() calls due to ML_QUEUE_HOST_BUSY.
fc_exch_alloc() used to try all the available exchange managers in the
list for an available exchange id, but this was changed in 2010 so that
if the first matched exchange manager couldn't allocate one, it fails
and we end up returning host busy. This was due to commit:
Setting the ddp_min module parameter to fcoe to 128MB prevents the
->match function from permitting the use of the offload exchange manager
for the frame, and we no longer see the problem with host busy status,
since it uses the larger non-offloaded pool.
