Sorry for being a bit vague.

The above PR was for netbsd-6 tackled by

Initially, this set of changes were requested pulled up:

sys/arch/powerpc/include/psl.h			1.20
sys/arch/powerpc/include/userret.h		1.29, 1.30
sys/arch/powerpc/oea/altivec.c			1.30
sys/arch/powerpc/oea/oea_machdep.c		1.72
sys/arch/powerpc/powerpc/fpu.c			1.36

However, this resulted in build failures on netbsd-6, and was
subsequently reverted, and later on the following set of
revisions/patches were pulled up:

sys/arch/powerpc/include/userret.h              1.29-1.30 (patch)
sys/arch/powerpc/oea/oea_machdep.c              1.72 (patch)
sys/arch/powerpc/include/psl.h                  1.20 (patch)

with this text:

	Add a check to make sure that if PSL_FP is set, we own the FPU.
	Don't clear PSL_FP/PSL_VEC.
	Don't preserve PSL_FP/PSL_VEC in cpu_setmcontext.
	[matt, ticket #1310]

It's this latter set of files I've updated via "cvs update -r netbsd-6"
and I'm otherwise using 6.1 release sources.

The fixes should be part of 6.2 when/if we release it.
