Ralf Baechle 569f75bd02 Use an irq_enable_hazard hazard barrier in unmask_mips_irq. This
hasn't been an actual bug, so it's more a change to be 100% compliant
with the requirements of the architecture spec.  Similar fix to
mask_mips_irq where there was a slightly less theoretical chance of
getting hit.

Jesse Barnes 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.

Russell King 9480e307cd [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks
In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

Greg Kroah-Hartman 53f4654272 [PATCH] Driver Core: fix up all callers of class_device_create()
The previous patch adding the ability to nest struct class_device
changed the paramaters to the call class_device_create().  This patch
fixes up all in-kernel users of the function.
