[PATCH 0/3] rtc,x86: RTC CMOS refactoring

["Mateusz Jończyk" <mat.jonczyk@o2.pl>]

Hello,

The main aim of this series is to remove duplicated code in
mach_get_cmos_time() in arch/x86/kernel/rtc.c . This function performed
the same thing as mc146818_get_time() - reading the time from the CMOS
RTC - but used a different algorithm. So modify it to use standard
mc146818_get_time().

First, to make these functions more similar to each other (and also for
another reason described in the patch), reduce the polling period in
mc146818_get_time(). Then, rewrite mach_get_cmos_time().

The last patch renames a function in arch/x86/kernel/rtc.c.

I have tested this on three different computers.

Greetings,
Mateusz
