01d42abdf3 Using get_nasid() to find the console node will blow up nicely if
called on a another node than the console node, so use the master_nasid
instead and in the unlikely case that one isn't initialized yet, fall
back to get_nasid().

a3701ca487 When CONFIG_PM is enabled, it uses the TOY_MATCH2 interrupt as the system
timer tick. Prior to this patch, if IDE IRQ probing occured, then the
TOY_MATCH2 interrupt would be permanently disabled, and no system timer
tick occurs. This patch corrects this situation by correctly registering
the TOY_MATCH2 interrupt so that IDE IRQ probing doesn't have adverse
side effects.

f8977d0a9b [PATCH] PCI fixup for Toshiba laptops and ohci1394
This is a fix for a bug I see on my Toshiba laptop, where the ohci1394
controller gets initialized improperly.  The patch adds two PCI fixups
to arch/i386/pci/fixup.c, one that happens early on to cache the value
of the PCI_CACHE_LINE_SIZE config register, and another that later
restores the value, along with a valid IRQ number and some BAR values.
I've tested it on my laptop, and it prevents me from running into what I
consider to be a major bug: IRQ 11 is disabled by the IRQ debug code,
causing my wireless to break.

Thanks to Rob for the original patch to ohci1394.c and Stefan for lots
of proofreading (and a last minute bug caught in review!) and additional
information collection.  I think the DMI system list is correct, but we
may need to add some more PCI IDs to the PCI_FIXUP macros over time.
