PM QoS constraints like the CPU_DMA_LATENCY, when set, apply to all cpus. The
QoS guarantees performance, at the expense of power. There is an opportunity to
save power on the cpus, if a subset of cpus need not participate in honoring
the QoS request.

This is part of version 8 of 'ARM: kprobes: enable OPTPROBES for ARM32'.
Its main goal is introducing checker mechanism to give a chance to
detail check each probed instructions. Different from previous version,
this series redesign stack checker following Tixy's advise:
https://lkml.org/lkml/2014/
This patch prohibit probing instructions for which the stack
requirement are unable to be determined statically. Some test cases
are found not work again after the modification, this patch also
removes them.
v1 -> v2:
- Use MAX_STACK_SIZE macro instead of hard coded stack size.

This patch use previous introduced checker on store instructions,
record stack consumption informations to arch_probes_insn. With such
information, kprobe opt can decide how much stack needs to be
protected.
v1 -> v2:
- Bugfix and code improvements following Tixy's suggestion. See:
http://www.
This patch introdces 'checker' to decoding phase, and calls checkers
when instruction decoding. This allows further decoding for specific
instructions.
v1 -> v2:
- kprobe checker stubs are introduced in this patch.
