This patch adds support for rtc-efi (RTC Class Driver for EFI-based systems) to x86. This patch is based on dann frazier patch [add rtc platform driver for EFI -> http://lkml.org/lkml/2009/1/8/434], and also depends on dann's patch. Dann's patch was in the mm tree, though I think its been merged already. This patch has been tested and works perfectly on every x86 EFI system I could find, though all have been EL64 systems. I would appreciate any testing feedback from EL32 systems from anyone that has one and can test. Signed-off-by: Brian Maly
