X-Git-Tag: v2.6.36-rc4~9^2~23 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=df51e7aa2cf204e3a65657a1d60b96cfda133e9b;p=platform%2Fkernel%2Flinux-stable.git agp/intel: Promote warning about failure to setup flush to error. Make sure we always detect when we fail to correctly allocate the Isoch Flush Page and print an error to warn the user about the likely memory corruption that will result in invalid rendering or worse.
