Peter,

 How do you think this should be restructured (ideally)?

Maybe create a sub-directory (arch/x86/kernel/rtc) and in this 
sub-directory split the existing rtc.c code into:
(1) rtc.c for common code used by all RTC, 
(2) efi_rtc.c for EFI specific code
(3) cmos_rtc.c for cmos/legacy specific code

Anyone have any objections/concerns with this or perhaps have a better way?
