- Saa7134-core.c saa7134_irq(): Separate GPIO16 and GPIO18 handling. Call
IR-remote-GPIO handler only if the GPIO IRQ is "owned" by it. Added
infrastructure to branch out to a future I2C-IR IRQ handler.

trigger an IRQ that is wired as keyup/keydown mask. IRQ will only be
generated for an actual key-down event.
saa7134-input.c flyvideo_codes[]: Replace numpad keys with normal ones. Put
meaning to mystery keys. Change some key definitions to have their functions
match their labels better. Fix typos.

Various PCI bus errors can be signaled by newer PCI controllers.
Recovering from those errors requires an infrastructure to notify
affected device drivers of the error, and a way of walking through

I upgraded my Toshiba Satellite BIOS recently to see if it would fix an
ACPI related problem I have
(http://bugzilla.kernel.org/show_bug.cgi?id=5727). Unfortunately, it
didn't, and moreover, Toshiba chose to change the system version in the
DMI table with the update, causing the OHCI1394 related quirk to break.
This patch updates the DMI table for the quirk to include Toshiba's new
version name for this machine; I've tested it and it seems to work fine.

idr gently pointed out today that not only is the sysfs rom file

The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).

This patch disables power fault, MRL sensor and presence detection
interrupts when a PCIe slot is powered-off and enables those
interrupts when it is powered-on again. This is necessary to prevent
the associated events from causing an endless cycle of interrupts
due to the power-fault bit, which stays set till power is restored
to the slot.

I've implemented a quirk to take advantage of the 1KB I/O space
granularity option on the Intel P64H2 PCI Bridge. I had to change
probe.c because it sets the resource start and end to be aligned on 4k
boundaries (after the quirk sets them to 1k boundaries). I've tested
this patch on a Unisys ES7000-600 both with and without the 1KB option
enabled. I also tested this on a 2 processor Dell box that doesn't have
a P64H2 to make sure there were no negative affects there.

Patch from Deepak Saxena
In working on adding 36-bit addressed supersection support to ioremap(),
I came to the conclusion that it would be far simpler to do so by just
splitting __ioremap() into a main external interface and adding an
__ioremap_pfn() function that takes a pfn + offset into the page that
__ioremap() can call. This way existing callers of __ioremap() won't have
to change their code and 36-bit systems will just call __ioremap_pfn()
and we will not have to deal with unsigned long long variables.
Note that __ioremap_pfn() should _NOT_ be called directly by drivers
but is reserved for use by arch_ioremap() implementations that map
32-bit resource regions into the real 36-bit address and then call
this new function.
