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
arguments such as:

	-D__INT8_C(c)='c'

Converting these to form:

	-D'__INT8_C(c)'='c'

seems to fix the problem.

This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) /
82b89152 (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.

Until now flush_kernel_vmap_range() and invalidate_kernel_vmap_range() did
not exist on MIPS resulting in heavy cache corruption on XFS filesystems.

Left for the post-3.0 time: optimization and make this work with highmem,

The size is always valid, but variable-length arrays generate worse code
for no good reason (unless the function happens to be inlined and the
compiler sees the length for the simple constant it is).

Also, there seems to be some code generation problem on POWER, where
Henrik Bakken reports that register r28 can get corrupted under some
subtle circumstances (interrupt happening at the wrong time?).  That all
indicates some seriously broken compiler issues, but since variable
length arrays are bad regardless, there's little point in trying to
chase it down.

SFI tables reside in RAM and should not be modified once they are
written.  Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum.  This will
break kexec as the second kernel fails to validate SFI tables.

To fix this we use temporary variable for irq number.

The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

member of the 'gpio_bank' structure has been placed unconditionally in
function _set_gpio_wakeup(), which is always built. This resulted in the
