Currently, XPC's heartbeat timer function runs on whatever CPU modprobe/insmod
ran on when XPC was started. To avoid the heartbeat from being delayed for
long periods the timer function must run on CPU 0.

N.B. Altix doesn't currently allow cpu0 to be taken offline, so this is
safe for now.  This code must be revised when offline of cpu0 is enabled.

When the CPE handler encounters too many CPEs (such as a solid single
bit memory error), it sets up a polling timer and disables the CPE
interrupt (to avoid excessive overhead logging the stream of single
bit errors).  disable_irq_nosync() calls chip->disable() to provide
a chipset specifiec interface for disabling the interrupt.  This patch
adds the Altix specific support to disable and re-enable the CPE interrupt.

There is a section mismatch when building CONFIG_FLATMEM=y kernels
that also have CONFIG_HOTPLUG_CPU=y

WARNING: vmlinux.o(.text+0x5a902): Section mismatch: reference to \
.init.text:__alloc_bootmem (between 'per_cpu_init' and 'count_pages')

The issue occurs because per_cpu_init() in mm/contig.c is
marked __cpuinit (which is #define'd to nothing on a hot
plug cpu configuration) call __alloc_bootmem() (which is
an __init function).  The usage is actually safe because
the __alloc_bootmem() is inside an "if (first_time)" test
so that the call is only made while it is still legal to
do so.

But the warning is irritating.  Move the allocation to
find_memory().

  PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.
  PCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.
  PCI: Revert "PCI: disable MSI by default on systems with Serverworks HT1000 chips"

Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:

 - Do the INIT_WORK() before registering each LED, so if its trigger
   becomes immediately active it can schedule work without oopsing..

 - Use normal registration, not platform_driver_probe(), so that
   devices appearing "late" (hotplug type) can still be bound.

 - Mark the driver remove code as "__devexit", preventing oopses
   when the underlying device is removed.

These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.
