Convert fcoe_percpu array to use the per-cpu variables
that the kernel provides. Use the kernel's functions to

The cpu member of the fcoe_percpu_s is no longer needed,

Currently the skb_queue is initialized every time the associated
CPU goes online. This patch has libfcoe initializing the skb_queue
for all possible CPUs when the module is loaded.

This patch also re-orders some declarations in the fcoe_rcv()
function so the structure declarations are grouped before
the primitive declarations.

Lastly, this patch converts all CPU indicies to use unsigned int
since CPU indicies should not be negative.

A fix for a very serious and stupid bug in osd_initiator. It
used to call blk_put_request() regardless of if it was from
the end_io callback or if called after a sync execution.
It should call the unlocked version __blk_put_request() instead.

Also fixed is the remove of _abort_unexecuted_bios hack, and use of
blk_end_request(,-ERROR,) to deallocate half baked requests. I've
audited the code and it should be safe.

We have a problem with recovered error handling in that any command
which goes down as BLOCK_PC but which returns a sense code of RECOVERED
ERROR gets completed with -EIO.  For actual SG_IO commands, this doesn't
matter at all, since the error return code gets dropped in favour of
req->errors which contain the SCSI completion code.

However, if this command is part of the block system, then it will pay
attention to the returned error code.  In particularly if a SYNCHRONIZE
CACHE from a barrier command completes with RECOVERED ERROR, the
resulting -EIO on the barrier causes block to error the request and
return it to the filesystem.  Fix this by converting the -EIO for
recovered error to zero, plus remove the printing of this from sd and sr
so the message isn't double printed.

aic79xx leaves timers inserted when ahd_init() (which inserts
two timers at its very end) succeeds but ahd_pci_map_int()
fails. In this case ahd->init_level gets incremented to 5 only
when that function succeeds, but ahd_free() calls ahd_shutdown()
only when ahd->init_level == 5, and ahd_shutdown() is where the
timers get removed. Since the freeing of the IRQ is not controlled
by ahd->init_level, we should increment init_level prior to
calling ahd_pci_map_int().

When IRQs are shared by multiple controllers and if the first one
to register does not disable the IRQ, then IRQ will be enabled
for all other controllers by default, irrespective of their
setting. With IRQF_DISABLED registration, the driver interrupt
routine was called with interrupt enabled always. Disbaling the
registration with IRQF_DISABLED, since driver code is re-entrant
safe and all critical sections are guarded with interrupt safe
locks.

This patch fixes a problem of possible dropped interrupts. Currently,
the ibmvfc driver has a race condition where after ibmvfc_interrupt
gets run, the platform code clears the interrupt. This can result in
lost interrupts and, in worst case scenarios, result in command
timeouts. Fix this by implementing a tasklet similar to what the
ibmvscsi driver does so that interrupt processing is no longer done in
the actual interrupt handler, which eliminates the race.
