Here is an updated version of a patch I wrote 6 years ago
http://marc.info/?l=linux-sparc&m=103939103607617&w=2
that simplifies interrupt mask lookup.  It's main purpose
is to add VME bus support but it's really a cleanup of the mask code.

Since the first argument is always NULL, the only side effect

This is the only use of the clear_profile_irq() btfixup entry,
which just eats up lots of dead space on other platform types.

A subsequent commit will delete the other implementations and
the btfixup entry as well.

We no longer put the top-level PCI controller device into the
PCI layer device list.  So pbm->pci_bus->self is always NULL.

Therefore, use direct PCI config space accesses to get at
the PCI controller's PCI_STATUS register.

PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored
the DMA mask for IDE and SCSI transfers.  This is wrong - we have
no DMA translation hardware.  We want to obey DMA masks so that the
block layer performs bouncing itself.

As noticed by Russell King, we were not setting this properly
to the number of entries, but rather the total size.

We need to pass IRQF_SHARED, otherwise we get things like:

As sparse warns, without this struct page pointer subtraction is
extremely expensive, and this is a pretty common operation in
fast paths.

With this define struct page becomes 64 bytes which makes for a
simple subtract and shift, instead of a costly divide or reciprocol
multiply.

Otherwise sparse doesn't work.  The 32 vs. 64 header ifdef
used under arch/sparc/include/asm/ is:

#if defined(__sparc__) && defined(__arch64__)

And that doesn't work for sparse unless we give it __arch64__

Change the MN10300 fault handler to make it check in_atomic() rather than
in_interrupt() as commit 6edaf68a did for other
architectures:

	Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
	Date:   Wed Dec 6 20:32:18 2006 -0800

	[PATCH] mm: arch do_page_fault() vs in_atomic()

	In light of the recent pagefault and filemap_copy_from_user work I've
	gone through all the arch pagefault handlers to make sure the
	inc_preempt_count() 'feature' works as expected.

	Several sections of code (including the new filemap_copy_from_user)
	rely on the fact that faults do not take locks under increased preempt
	count.

OMAPs MMC device data was passing the wrong structure via the platform
device.  Moreover, a missing function means that both sx1_defconfig

errors.  Fix this by updating the MMC support from the omapzoom tree.
