[This]patch is a bit more involved. The patch addresses a gcc
regression in the 4.3 series (specifically this patch is against 4.3.2
which does *not* have a lot of other issues which affect kernel building)

GCC bug tracker has this issue as
#38453 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38453
#32044 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32044

comment 65 of #32044 has the fix being applied to gcc trunk as revision #142719

The attached patch is a backport to gcc 4.3.2 which allows this
version to be used to generate correct output for various ARM kernel
build (and indeed is teh correct answer in general).
