I looked at applying this one to agpgart.git, as it's less controversial than the other patch. However,.. - MIME : just say no. I had to hand fix up a few things before git would even see that I was feeding it a diff. - No Signed-off-by: line. - The diff adds trailing whitespace. This makes git sad also. (This problem also affects the other diff, which is possibly why...) - Finally.. error: patch failed: drivers/char/agp/generic.c:1076 error: drivers/char/agp/generic.c: patch does not apply error: patch failed: drivers/char/agp/intel-agp.c:256 error: drivers/char/agp/intel-agp.c: patch does not apply Perhaps this diff should have have been [1/2] instead. Can you fix those up, and resend this one? The other diff I want to chew over some more before applying, especially after Arjan's comments.
