We take the spin_lock again in fail_all_cmds() so we need to unlock here.

cciss: factor out scatter gather chain block mapping code
Rationale is I want to use this code from the scsi half of the
driver.

cciss: fix scatter gather chain block dma direction kludge2010-02-28T18:42:31+00:00Stephen M. Cameronscameron@beardog.cce.hp.com2010-02-26T22:01:32+00:00urn:sha1:2ad6cdc20fbeea1e1744190c00cebb64e4b4c491
cciss: fix scatter gather chain block dma direction kludge
The data direction for the chained block of scatter gather
elements should always be PCI_DMA_TODEVICE, but was mistakenly
set to the direction of the data transfer, then a kludge to
fix it was added, in which pci_dma_sync_single_for_device or
pci_dma_sync_single_for_cpu was called. If the correct direction
is used in the first place, the kludge isn't needed.

cciss: simplify scatter gather code.
Instead of allocating an array of pointers to a structure
containing an SGDescriptor structure, and two other elements
that aren't really used, just allocate SGDescriptor structs.

Except for SCSI no device drivers distinguish between physical and
hardware segment limits. Consolidate the two into a single segment
limit.

block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectors2010-02-26T12:58:08+00:00Martin K. Petersenmartin.petersen@oracle.com2010-02-26T05:20:38+00:00urn:sha1:086fa5ff0854c676ec333760f4c0154b3b242616
The block layer calling convention is blk_queue_<limit name>.
blk_queue_max_sectors predates this practice, leading to some confusion.
Rename the function to appropriately reflect that its intended use is to
set max_hw_sectors.
Also introduce a temporary wrapper for backwards compability. This can
be removed after the merge window is closed.
