[PATCH v2 00/11] riscv: kprobes: Clean up instruction simulation

[Nam Cao]

Hi,

There is some instruction-processing code in kprobes simulate code. These
code should be insn.h. In fact, most of them is duplicating insn.h.

This series remove the duplicated bits and make use of macros already
defined in insn.h. The non-duplicated bits are moved into insn.h.

v2:
  rebase on top of Alex's patches [1]. This means replacing RV_X with
  RV_X_mask for the first 2 patches. The rest is the same.
