This avoids some potential stack overflows with very deep softirq callchains.

Save a byte here and there. Ultimatively useless, but these things always
catch my eyes when reading the code so just fix them for now.
Also I got at least one patch fixing of them already, which gives a good
excuse.

Icecream preprocesses c sources locally, and sends the result off to a remote
host for compiling. It does not recognize includes at assembler level. The
fix is to put the assemberincludes an a separate .s file, which will always be
assembled locally.

This patch will create machinecheck sysdev directories per CPU. All of the
cpus still share the same ctl banks. When compiled with CONFIG_HOTPLUG_CPU,
it will also bring up/down sysdev directories as cpus go up/down. I have
tested the patch along with CONFIG_HOTPLUG_CPU option on in 2.6.13-rc1 kernel.

When the x86_64 cpu hotplug changes went in it added a check in
default_do_nmi() which kills NMI delivery on any CPU but the BSP.
The NMI watchdog is brought up quite some time before the online bit is set
in num_online_cpus so this won't work very well. The nmi watchdogs on cpus
that are not BSP will never be reprogrammed and no NMIs.
Why was this check added? How does an offlined cpu receive an NMI?

I ran glade-2 on the glade file, fixed two missing stock icons and
cleaned up the C code that inserts the single/split/full modes. The
rest of the patch is minor cleanups only. I refrained from using all
the included xpm icons in images.c (like qconf.cc does) in favour of
using the stock Gtk+ icons instead. Oh, yes there was a "back" bug
in split mode that I also removed, oh well...
It has been tested with success by several people, including
Jesper Juhl, Randy Dunlap and myself.

It may shut up gcc, but it also incorrectly changes the semantics of the
smp_call_function() helpers.
You can fix the warning other ways if you are interested (create another
inline function that takes no arguments and returns zero), but
preferably gcc just shouldn't complain about unused return values from
statement expressions in the first place.

Apparently gcc 4.0 complains about "({ 0; });", which leads to -Werror
breakage in one of the alpha oprofile modules.
One might could argue that this is a gcc bug, in that statement-expressions
should be considered to be function-like rather than statement-like for the
purposes of this warning. But it's just as easy to use an inline function
in the first place, side-stepping the issue.

sys_reboot() now calls device_suspend(), so it is no longer necessary for
the e1000 driver to register a reboot notifier [in fact doing so results in
e1000_suspend() getting called twice].
(akpm: we need to fast-track this. It's causing ia64 to oops on shutdown)

Implement kernel labeling of the MLS (multilevel security) field of
security contexts for files which have no existing MLS field. This is to
enable upgrades of a system from non-MLS to MLS without performing a full
filesystem relabel including all of the mountpoints, which would be quite
painful for users.
With this patch, with MLS enabled, if a file has no MLS field, the kernel
internally adds an MLS field to the in-core inode (but not to the on-disk
file). This MLS field added is the default for the superblock, allowing
per-mountpoint control over the values via fixed policy or mount options.
This patch has been tested by enabling MLS without relabeling its
filesystem, and seems to be working correctly.

This patch:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111955644929114&w=2
uncovered a k7m bios bug, where the VT82C686A router is reported as
being "586-compatible". The two chips have different pirq mapping, so
this leads to "irq routing conflict" on many pci devices.
The suggested fix was discussed with Aleksey Gorelov, who helped me
to identify the problem as a probable bios bug.

This patch adds per disk queue functionality to cciss. Sometime back I
submitted a patch but it looks like only part of what I needed. In the 2.6
kernel if we have more than one logical volume the driver will Oops during
rmmod. It seems all of the queues actually point back to the same queue.
So after deleting the first volume you hit a null pointer on the second
one.
This has been tested in our labs. There is no difference in performance,
it just fixes the Oops.

Debugging and description from: Noah Misch <noah@cs.caltech.edu>
When a driver calls pcmcia_request_irq with IRQ_HANDLE_PRESENT unset, it looks
for an open IRQ by request_irq()ing with a dummy handler and NULL dev_info.
free_irq uses dev_info as a key for identifying the handler to free among
those sharing an IRQ, so request_irq returns -EINVAL if dev_info is NULL and
the IRQ may be shared. That unknown error code is the -EINVAL.
It looks like only pcnet_cs and axnet_cs are affected. Most other drivers let
pcmcia_request_irq install their interrupt handlers. sym53c500_cs requests
its IRQ manually, but it cannot share an IRQ.
The appended patch changes pcmcia_request_irq to pass an arbitrary, unique,
non-NULL dev_info with the dummy handler.
