between 2.6.15-git7 and 2.6.15-git8 we started getting hundreds of
compile warnings:
-git7: http://test.kernel.org/20295/debug/test.log.0
-git8: http://test.kernel.org/20402/debug/test.log.0
Warnings look like this:
include/asm/bitops.h: In function `load_elf32_binary':
include/asm/bitops.h:30: warning: read-write constraint does not allow a
register
include/asm/bitops.h:30: warning: read-write constraint does not allow a

What do these mean? And how do we get rid of it?
Presumably caused by this:

They mean you have a buggy compiler.

It was the bitops.h constrain change.
The problem is that reverting them would be readding the problem. Maybe we need to
#ifdef it.
