When a file supplied via CONFIG_INITRAMFS pointed to a file
for which kbuild had a rule to compile it (foo.c => foo.o)
then kbuild would compile the file before adding the
file to the initramfs.
Teach make that files included in initramfs shall not be updated by adding
an 'empty command'. (See "Using Empty Commands" in info make).

Record the most recently used allocation group on the allocation context, so
that subsequent allocations can attempt to optimize for contiguousness.
Local alloc especially should benefit from this as the current chain search
tends to let it spew across the disk.

We were storing cluster count on the ocfs2_super structure, but never
actually using it so remove that. Also, we don't want to populate the
uptodate cache with the unlocked block read - it is technically safe as is,
but we should change it for correctness.

Remove system device class for xpram. It creates the directory hierarchy
under /sys/devices/system/xpram/xpram0. The xpram0 directory is empty and
it is always created while xpram1 and following devices are always missing,
independent if the devices exist or not. Since the xpram devices are
listed in /proc/partitions and /sys/block/ as slram<x> the system device
class for xpram is meaningless.

I/O on a CCW device may stall if a channel path to that device is
logicaly varied off/on. A user I/O interrupt can get misinterpreted
as interrupt for an internal path verification operation due to a
missing check and is therefore never reported to the device driver.
Correct check for pending interruptions before starting path

- Replace scsi_device_types array API with scsi_device_type function API.
Gets rid of a lot of common code, as well as being easier to use.
- Add the new device types in SPC4 r05a, and rename some of the older ones.
- Reformat the printing of inquiry data; now fits on one line and
includes PQ.
I think I've addressed all the feedback from the previous versions. My
current test box prints:

This patch corrects a problem in mptfc which can result in targets
being removed after executing an "lsiutil 99" reset of the fibre

due to an inappropriate optimization in the event processing logic.
Every rescan event is now queued for execution and the setup reset

Currently it is impossible to reset provided by Qlogic QLA2xxx driver
SCSI devices externally using corresponding sg devices, particularly via
sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset()
function checks if the input scsi_cmnd has its private data (CMD_SP())
attached. Then the found pointer isn't used anywhere inside of
qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it
doesn't have such private data.
The attached patch removes check for non-NULL CMD_SP() from
qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using
corresponding sg devices.
AV: change applies to bus/host reset handlers as well.
