Hi,
I'd like to submit the attached patch to add Ivy Bridge processor support to the
processor type menu in menuconfig. Setting this configures the appropriate
CFLAGS (core-avx-i) for ivy bridge.
As this is my first kbuild patch, could somebody review it and let me know what
I've done wrong. ;-)
Thanks
Alec.
