This is v17 patch series of kprobeopt. The main change in this version
are:
1. Patch 02/11 remove 3 useless ARM decode actions.
2. Patch 10/11 collects register usage of probed instructions.
3. Patch 11/11 use register usage information to decide whether
the probed instruction needs simulation or emulation. In most
of the case, the probed instruction is copied into code template
and get executed during restoring.
Jon Medhurst (Tixy) (2):
ARM: kprobes: Add test cases for stack consuming instructions
ARM: kprobes: Fix unreliable MRS instruction tests
Masami Hiramatsu (1):
kprobes: Pass the original kprobe for preparing optimized kprobe
Wang Nan (8):
ARM: probes: move all probe code to dedicate directory
ARM: kprobes: remove unused ARM decoder actions.
ARM: kprobes: introduces checker
ARM: kprobes: collects stack consumption for store instructions
ARM: kprobes: disallow probing stack consuming instructions
ARM: kprobes: enable OPTPROBES for ARM 32
ARM: kprobes: check register usage for probed instruction.
ARM: optprobes: execute instruction during restoring if possible.
