Re: x86_64 compile spewing hundreds of warnings - started 2.6.15-git8

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 register include/asm/bitops.h:65: warning: read-write constraint does not allow a register include/asm/bitops.h:65: warning: read-write constraint does not allow a register 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 register include/asm/bitops.h:65: warning: read-write constraint does not allow a register include/asm/bitops.h:65: warning: read-write constraint does not allow a register 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 register include/asm/bitops.h:65: warning: read-write constraint does not allow a register include/asm/bitops.h:65: warning: read-write constraint does not allow a register

What do these mean? And how do we get rid of it?

Presumably caused by this:

http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=636dd2b7def5c9c72551b51d4d516a65c269de08

or this:

http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=92934bcbf96bc9dc931c40ca5f1a57685b7b813b

There were rumblings about changing these checks around a bit, but
nothing happened and the warnings are still there ... any chance of
fixing this?
