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
