The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

For the pxa part, that looks fine to me.
I'd like to focus a bit of Russell's attention to the sa11xx part (reminder in
[1]), and more specifically :

 - the change to drivers/pcmcia/soc_common.c
 - the change to drivers/pcmcia/sa1111_generic.c

I must admit my knowledge of PCMCIA is relatively poor, and even if the patch
looks harmless, one never knows if Assebet will ever by same after ...

Cheers.
