The driver uses msleep_interruptible() in the code path responsible
for resetting the card's ports via the lsiutil command. If a
<ctrl-c> is received during the reset it can leave a port in such
a state that the only way to regain its use is to reboot the system.
Changing from msleep_interruptible() to msleep() corrects the problem.

While doing board reset testing I was able to put the system in
an infinite request/response loop between the scsi layer and
mptscsih_qcmd() by aborting the reset. This patch installs
a "SETUP RESET" handler which calls fc_remote_port_delete()
for all registered rports. This blocks the target which
prevents the loop. Additionally, should the reset fail to
complete, the transport will now terminate i/o to the target.

The fibre channel firmware provides a timer which is similar in purpose
to the fibre channel transport's device loss timer. The effect of this
timer is to extend the total time that a target will be missing beyond
the value associated with the transport's timer. This patch changes
the firmware timer to a default of one second which significantly reduces
the lag between when a target goes missing and the notification of the
fibre channel transport.

The add_preferred_console call in rtas_console.c was not causing the
console to be selected. It turns out that the add_preferred_console was
being called after the hvc_console driver was registered. It only works
when it is called before the console driver is registered.
Reorder hvc_console.o after the hvc_console drivers to allow the selection
during console_initcall processing.

Apply some alterations to the memory barrier document that I worked out
with Paul McKenney of IBM, plus some of the alterations suggested by Alan
Stern.
The following changes were made:
(*) One of the examples given for what can happen with overlapping memory
barriers was wrong.
(*) The description of general memory barriers said that a general barrier is
a combination of a read barrier and a write barrier. This isn't entirely
true: it implies both, but is more than a combination of both.
(*) The first example in the "SMP Barrier Pairing" section was wrong: the
loads around the read barrier need to touch the memory locations in the
opposite order to the stores around the write barrier.
(*) Added a note to make explicit that the loads should be in reverse order to
the stores.
(*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences"
section to make them clearer. Added a couple of diagrams to make it more
clear as to how it could go wrong without the barrier.
(*) Added a section on memory speculation.
(*) Dropped any references to memory allocation routines doing memory
barriers. They may do sometimes, but it can't be relied on. This may be
worthy of further documentation later.
(*) Made the fact that a LOCK followed by an UNLOCK should not be considered a
full memory barrier more explicit and gave an example.

Doing PCI config space accesses to non-present PCI slots
can result in fatal JBUS errors if the PCI config access
hypervisor call is performed on cpus other than the boot
cpu.
PCI config space accesses to present PCI slots works just
fine.
Recursively traverse the OBP device tree under the PCI
controller node and record all present device IDs into
a small hash table.
Avoid the hypervisor call for any PCI config space access
attempt for a device not recorded in the hash table.

kbuild does explicitly specify what to do in all cases, and each
time make's built-in rules & variables has been used it has been a bug.
So to speed up things and to avoid the hard-to-debug error situations
ignore the built-in definitions.
If any part of the kernel uses the built-in definitions the build will
just stop there and it should be trivial to fix.

Get rid of all the SUN_570X logic and instead:
1) Make sure MEMARB_ENABLE is set when we probe the SRAM
for config information. If that is off we will get
timeouts.
2) Always try to sync with the firmware, if there is no
firmware running do not treat it as an error and instead
just report it the first time we notice this condition.
3) If there is no valid SRAM signature, assume the device
is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT.

The binrpm-pkg target uses KERNELRELEASE when generated its .spec file.
When binrpm-pkg was the first build target run in a tree it generated the

As fs/nfs/inode.c is rather large, heterogenous and unwieldy, the attached
patch splits it up into a number of files:
(*) fs/nfs/inode.c
Strictly inode specific functions.
(*) fs/nfs/super.c
Superblock management functions for NFS and NFS4, normal access, clones
and referrals. The NFS4 superblock functions _could_ move out into a
separate conditionally compiled file, but it's probably not worth it as
there're so many common bits.
(*) fs/nfs/namespace.c
Some namespace-specific functions have been moved here.
(*) fs/nfs/nfs4namespace.c
NFS4-specific namespace functions (this could be merged into the previous
file). This file is conditionally compiled.
(*) fs/nfs/internal.h
Inter-file declarations, plus a few simple utility functions moved from
fs/nfs/inode.c.
Additionally, all the in-.c-file externs have been moved here, and those
files they were moved from now includes this file.
For the most part, the functions have not been changed, only some multiplexor
functions have changed significantly.
I've also:
(*) Added some extra banner comments above some functions.
(*) Rearranged the function order within the files to be more logical and
better grouped (IMO), though someone may prefer a different order.
(*) Reduced the number of #ifdefs in .c files.
(*) Added missing __init and __exit directives.

Respond to a moved error on NFS lookup by setting up the referral.
Note: We don't actually follow the referral during lookup/getattr, but
later when we detect fsid mismatch in inode revalidation (similar to the
processing done for cloning submounts). Referrals will have fake attributes
until they are actually followed or traversed.
