Subject[PATCH v5 0/3] kprobes: arm: enable OPTPROBES for ARM 32
Date
Following 3 patches are the 5th version of kprobe optimization for arm.
The main difference is disallowing optimize stack store instructions,
such as "str r0, [sp]" and "push {r0 - r4}".

The first patch improve arm instruction decoder to detect such
instructions, following 2 patches make it unoptimizable.

Wang Nan (3):
ARM: probes: check stack operation when decoding
kprobes: copy ainsn after alloc aggr kprobe
kprobes: arm: enable OPTPROBES for ARM 32
