Without the patch, the machine hangs as soon as I touch one of the first 10
pages of /proc/vmcore that are mapped to the GART region. (On a different
mechine, this caused a strange MCE and reboot.)
With the patch, I was able to read the full /proc/vmcore.
I manually verified the ELF header of /proc/vmcore and the patch works as intended
(the section containing the GART region hsa been split in two to exclude GART).

I haven't given this any thought yet. I can look at it later...
