in the GPIOLIB=n case, the gpio headers need to be reshuffled

This patch removes the last hardcoded base address from the au1000_eth
driver. The base address of the MACDMA unit was derived from the
platform device id; if someone registered the MACs in inverse order
both would not work.
So instead pass the base address of the DMA unit to the driver with
the other platform resource information.

It seems the shell chokes because sparse is called with command line

Converting these to form:
-D'__INT8_C(c)'='c'
seems to fix the problem.

82b89152f0 (kernel.org) [MIPS: LD/SD o32
macro GAS fix update].
Turns out this patch is producing many build errors with gcc 4.2. Based
on further testing with a test case extracted from the build errors found
further build errors and suboptimal generation even in violation of the
"R" constraint.
To make matters worse, the binutils changes also don't work quite as
intended so revert this patch for now.
If Open Firmware / Device Tree support is enabled on a SNI RM kernel both
<asm/mipsprom.h> and <asm/prom.h> will be included into some .c files.
Since both headers use the same wrapper symbol only the inclusion of the
first file will have an effect but the 2nd file will be ignored resulting
in a build error.

Page table entries are made invalid by writing a zero into the the PTE
slot in a page table. This creates a race condition with the TLB
modify handlers when they are updating the PTE.
CPU0 CPU1
Test for _PAGE_PRESENT
. set to not _PAGE_PRESENT (zero)
Set to _PAGE_VALID
So now the page not present value (zero) is suddenly valid and user
space programs have access to physical page zero.
We close the race by putting the test for _PAGE_PRESENT and setting of
_PAGE_VALID into an atomic LL/SC section. This requires more registers
than just K0 and K1 in the handlers, so we need to save some registers
to a save area and then restore them when we are done.
The save area is an array of cacheline aligned structures that should
not suffer cache line bouncing as they are CPU private.
