9a8f99fab0 powerpc/rtas-rtc: remove sideeffects of printk_ratelimit
Don't use printk_ratelimit() as an additional condition for returning
on an error. Because when the ratelimit is reached, printk_ratelimit
will return 0 and e.g. in rtas_get_boot_time won't check for an error
condition.

507279db18 [PATCH] powerpc: reorg RTAS delay code
This patch attempts to handle RTAS "busy" return codes in a more simple
and consistent manner.  Typical callers of RTAS shouldn't have to
manage wait times and delay calls.

This patch also changes the kernel to use msleep() rather than udelay()
when a runtime delay is necessary.  This will avoid CPU soft lockups
for extended delay conditions.

0e8ed47912 [PATCH] powerpc: RTC memory corruption
We should be memset'ing the data we are pointing to, not the pointer
itself.  This is in an error path so we probably don't hit it much.

49e16b7bec powerpc: time-of-day fixes for 32-bit CHRP systems
This makes 32-bit CHRP systems use the RTAS time-of-day routines if
available.  It fixes a bug in the RTAS time-of-day routines where they
were storing a 64-bit timebase value in an unsigned long by making
those variables u64.  Also, the direct-access time-of-day routines
had the wrong convention for the month and year in the struct rtc_time.

3136254ca5 [PATCH] powerpc: kill ppc64 rtc.c, use genrtc instead
This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel,
and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate
of the genrtc functionality. Also enable build of genrtc for
CONFIG_PPC64 (it just works are we already have the required callbacks)
and enable it in all defconfigs.
