This update includes the usual round of major driver updates (ncr5380,
lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas). There's also
an assortment of minor fixes, mostly in error legs or other not very
user visible stuff. The major change is the pci_alloc_irq_vectors
replacement for the old pci_msix_.. calls; this effectively makes IRQ
mapping generic for the drivers and allows blk_mq to use the
information.

Now that all conversions are done, move the FibreChannel bsg code over
to the bsg library.
This patch is derived from work done by Mike Christie in 2011 [1] but
only the iscsi parts got merged back then.

fc_destroy_bsgjob() and bsg_destroy_job() are now 1:1 copies, so use the
latter. As bsg_destroy_job() comes from bsg-lib we need to select it in
Kconfig once CONFOG_SCSI_FC_ATTRS is active.

The function bsg_goose_queue() does not have any in-tree callers,

iscsi_remove_host() uses bsg_remove_queue() which implements custom
queue draining. fc_bsg_remove() open-codes mostly identical logic.
The draining logic isn't correct in that blk_stop_queue() doesn't
prevent new requests from being queued - it just stops processing, so
nothing prevents new requests to be queued after the logic determines
that the queue is drained.
blk_cleanup_queue() now implements proper queue draining and these
custom draining logics aren't necessary. Drop them and use
bsg_unregister_queue() + blk_cleanup_queue() instead.

This file isn't using full modular functionality, and hence
can be "downgraded" to just using the export.h header.

Due to conflicts with the moduleh tree in linux-next, we
run into an include file mess. We really need export.h
in that tree, but if we add module.h locally then the
issue is easier to resolve.

This moves the FC classes bsg code to the block layer and
makes it a lib so that other classes like iscsi and SAS can use it.
It is helpful because working with the request queue, bios,
creating scatterlists, etc are a pain that the LLD does not
have to worry about with normal IOs and should not have to
worry about for bsg requests.
