c02ee1e5a9 scsi: qla2xxx: Change a stack variable into a static const variable
Make qla2x00_get_host_fabric_name() slightly faster by changing a stack
array into a static array. Declare that array const now that the
wwn_to_u64() argument pointer has been declared const.

c39e0af64b scsi: scsi_transport_fc: Add FPIN fc event codes
Add a new event type - an FPIN event.

Add a new routine, fc_host_fpin_rcv(), that lldd's call when an FPIN is
received. The routine processes the fpin payload.  For now, the routine
only logs an FPIN event.

2b1be55819 scsi: scsi_transport_fc: refactor event posting routines
There are two routines generating transport events that do the same thing
with only a couple of values set differently.

Refactor so there's a single routine doing the netlink operations to send
the event. All the differences are passed as arguments. Export the symbol
so the generic routine can be called by llds.

Modify the existing two event routines to use the helper.

fb24ea52f7 drivers: Remove explicit invocations of mmiowb()
mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:

	@mmiowb@
	@@
	- mmiowb();

and invoked as:

$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done

NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

72deb455b5 block: remove CONFIG_LBDAF
Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit
architectures.  These types are required to support block device and/or
file sizes larger than 2 TiB, and have generally defaulted to on for
a long time.  Enabling the option only increases the i386 tinyconfig
size by 145 bytes, and many data structures already always use
64-bit values for their in-core and on-disk data structures anyway,
so there should not be a large change in dynamic memory usage either.

Dropping this option removes a somewhat weird non-default config that
has cause various bugs or compiler warnings when actually used.

wakeup logic is dependent upon the LPFC_DRIVER_ABORTED flag. However, on

382e06d11e scsi: storvsc: Fix calculation of sub-channel count
When the number of sub-channels offered by Hyper-V is >= the number of CPUs
in the VM, calculate the correct number of sub-channels.  The current code
produces one too many.

This scenario arises only when the number of CPUs is artificially
restricted (for example, with maxcpus=<n> on the kernel boot line), because
Hyper-V normally offers a sub-channel count < number of CPUs.  While the
current code doesn't break, the extra sub-channel is unbalanced across the
CPUs (for example, a total of 5 channels on a VM with 4 CPUs).
