Subject: agp: drop vmalloc flag.
X-Git-Tag: v2.6.35-rc4~15^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=da931a931da85218add949266238c54b5fecd37f;p=platform%2Fkernel%2Flinux-3.10.git

agp: drop vmalloc flag.

Since the code that was too ugly to live is upstream, we can use it now,
instead of rolling our own.
