arch/powerpc: use printk_ratelimited instead of printk_ratelimit

2011-06-29T05:31:01+00:00

Since printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited.

powerpc/mpic: Simplify ipi cpu mask handling

2011-05-19T05:30:53+00:00

Now that MSG_ALL and MSG_ALL_BUT_SELF have been eliminated,
smp_mpic_mesage_pass no longer needs to lookup the cpumask just to
have mpic_send_ipi extract part of it and recode it in a NR_CPUS loop
by mpic_physmask.

powerpc: Remove checks for MSG_ALL and MSG_ALL_BUT_SELF

2011-05-19T04:30:46+00:00

Now that smp_ops->smp_message_pass is always called with an (online) cpu
number for the target remove the checks for MSG_ALL and MSG_ALL_BUT_SELF.

powerpc/mpic: Break cpumask abstraction earlier

2011-05-19T04:30:45+00:00

mpic_set_affinity is allocating and freeing a cpumask var even though
it was breaking the cpumask abstraction when passing the mask to
mpic_physmask.  It also didn't have any check for allocatin failure.

Break the cpumask abstraction earlier and use simple bitwise and of the
bits from the mask with the bits of cpu_online_mask.

powerpc/mpic: Limit NR_CPUS loop to 32 bit

2011-05-19T04:30:45+00:00

mpic_physmask was looping NR_CPUS times over a mask that was passed as
a u32. Since mpic is architecturaly limited to 32 physical cpus, clamp
the logical cpus to 32 when compiling (we could also clamp at runtime
to nr_cpu_ids).

PM / PowerPC: Use struct syscore_ops instead of sysdevs for PM

2011-05-11T19:37:15+00:00

Make some PowerPC architecture's code use struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.
