Ok.. I'll check that link, but what you posted didn't have the files
(mempolicy.h & policy.c) in the patch:

[mcd@arrakis numa_api]$ diffstat numa_api-01-core.patch
 include/linux/gfp.h   |   25 +++++++++++++++++++++++--
 include/linux/mm.h    |   17 +++++++++++++++++
 include/linux/sched.h |    4 ++++
 kernel/sys.c          |    3 +++
 mm/Makefile           |    1 +
 5 files changed, 48 insertions(+), 2 deletions(-)

Maybe it got lost somewhere between your mailer and mine?  The patch you
posted to LKML yesterday was clearly done without the -N option to diff:

diff -u linux-2.6.5-numa/kernel/sys.c-o linux-2.6.5-numa/kernel/sys.c

I don't know why.  The same code addition is in both the 'core' patch
and the 'shm' patch.  Adding it twice causes patch throw a reject.

Well, if for no other reason than all the code isn't posted!
