I'm currently involved in a project which aims to use a RapidIO fabric as,

multitude of processing elements, rather than a host + some dumb
peripherals.
Unfortunately, it appears that Freescale's rapidio controller is

We want to update the sched_group_powers when balance_cpu == this_cpu.
Currently the group powers are updated only if the balance_cpu is the first

The FEC on 5121 has problems with misaligned tx buffers.
The RM says any alignment is ok but empirical results
show that packet buffers ending in 0x1E will sometimes
hang the FEC. Other bad alignment does not hang but will
cause silent TX failures resulting in about a 1% packet
loss as tested by

This patch ports the kprobe-based event tracer to powerpc. This patch
is based on x86 port. This brings powerpc on par with x86.

v2:
- Removed regs_get_argument_nth() API as function argument access syntax
is dropped from kprobe-tracer. Please refer to mails below on Linux PPC
