hm, the one mm/migrate.c fix we had is already in -rc1:
b9255850: mm: Adjust do_pages_stat() so gcc can see copy_from_user() is safe
I've Cc:-ed more folks.

I have verified the build tree and am building from -rc1 only. The fix you've
mentioned above is also part of it.
debian-build:/tmp/all-yes-config/2.6.33-rc1# cat Makefile |grep EXTRAVERSION
EXTRAVERSION = -rc1
Must be a newer bug then.

Ritesh

That *is* the error report that he is describing. What version of gcc
is he using? It might be dumber than the one I have.

No, it's the same one, but different gcc. Sigh.

I was also successed build.
my environment is here:
2.6.33-rc1
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS=y
gcc version 4.4.2 20091027 (Red Hat 4.4.2-7) (GCC)
