[PATCH] PCI: update Toshiba ohci quirk DMI table
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

Documentation/filesystems/sysfs-pci.txt corrects the latter problem; the
former is a userland ABI now though, so we're stuck with it for awhile
at least.
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).

[ARM] 3070/2: Add __ioremap_pfn() API
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.
