unused isa_...() helpers removed.
Adrian Bunk:
The asm-sh part was rediffed due to unrelated changes.

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.

Patch from Deepak Saxena
Mark the ioremap'd cookie/pointer in said functions as const since
we should not be actualy touching the data. This fixes a slew of
compile warnings on IXP4xx as our reads[bwl] already mark this
parameter as const.

The "align" argument in ARMs __ioremap is unused and provides a
misleading expectation that it might do something. It doesn't.
Remove it.

Including asm/hardware.h into asm/io.h can cause #define clashes
between platform specific definitions and driver local definitions.

Add 'volatile' to the __iomem pointers for these functions as
per x86.

Patch from Lennert Buytenhek
This patch conditionalises the io{read,write}{8,16,32} defines and the
prototypes for ioport_map/ioport_unmap in asm-arm/io.h on ioread8 not
already having been defined. This is done so that platforms can provide
their own implementation of the iomap API, ixp2000 for example needs
this.

Patch from Olav Kongas
On ARM, the outX() and writeX() families of macros take the
result of cpu_to_leYY(), which is of restricted type __leYY,
and feed it to __raw_writeX(), which expect an argument of
unrestricted type. This results in 'sparse -Wbitwise'
warnings about incorrect types in assignments. Analogous
type mismatch warnings are issued for inX() and readX()
counterparts. The below patch resolves these warnings by
adding forced typecasts.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
