Revert "gpu/drm, x86, PAT: PAT support for io_mapping_*"
This reverts commit 17581ad812a9abb0182260374ef2e52d4a808a64. Sitsofe Wheeler reported that /dev/dri/card0 is MIA on his EeePC 900 and bisected it to this commit. Graphics card is an i915 in an EeePC 900: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 04) ( Most likely the ioremap() of the driver failed and hence the card did not initialize. ) Reported-by: Sitsofe Wheeler <sitsofe@yahoo.com> Bisected-by: Sitsofe Wheeler <sitsofe@yahoo.com> Cc: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
