powerpc: Merge machdep.h
A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void. Signed-off-by: Paul Mackerras <paulus@samba.org>
