Since iop13xx defines the PCI I/O spaces with physical resource addresses
the __io macro needs to perform the physical to virtual conversion.  I
incorrectly assumed that this would be handled by ioremap, but drivers
(like e1000) directly dereference the address returned from __io.

The ARM EABI requires doubleword (8-byte) stack alignment at all public entry
points.  The patch below makes the bFLT loader honour this.
It's always safe to start with a doubleword aligned stack so it doesn't seem
worth making this conditional on CONFIG_AEABI.

As reminded in http://lkml.org/lkml/2006/12/23/26, one should use
asm/hardware.h and asm/irq.h but absent-minded devs like me tends to use
asm/arch/hardware.h and/or asm/arch/irqs.h.
This patch aims at preventing such things.

In order to make it work, I had to modify asm-arm/irq.h too so that it can
be included from assembly files.
Also, as a side effect, I had to modify some headers who were using the
asm/arch/hardware.h or asm/arch/irqs.h.

The VM layer (on the face of it, fairly reasonably) expected that when
it does a ->writepage() call to the filesystem, it would write out the
full page at that point in time.  Especially since it had earlier marked
the whole page dirty with "set_page_dirty()".

But that isn't actually the case: ->writepage() does not actually write
a page, it writes the parts of the page that have been explicitly marked
dirty before, *and* that had not got written out for other reasons since
the last time we told it they were dirty.

That last caveat is the important one.

Which _most_ of the time ends up being the whole page (since we had
called "set_page_dirty()" on the page earlier), but if the filesystem
had done any dirty flushing of its own (for example, to honor some
internal write ordering guarantees), it might end up doing only a
partial page IO (or none at all) when ->writepage() is actually called.

That is the correct thing in general (since we actually often _want_
only the known-dirty parts of the page to be written out), but the
shared dirty page handling had implicitly forgotten about these details,
and had a number of cases where it was doing just the "->writepage()"
part, without telling the low-level filesystem that the whole page might
have been re-dirtied as part of being mapped writably into user space.

Since most of the time the FS did actually write out the full page, we
didn't notice this for a loong time, and this needed some really odd
patterns to trigger.  But it caused occasional corruption with rtorrent
and with the Debian "apt" database, because both use shared mmaps to
update the end result.

This fixes it. Finally. After way too much hair-pulling.
