[PATCH 0/6] ARM: kprobes: Fixes for ARM instruction emulation (part 4)

[Tixy]

(This is a fourth set of patches)

When kprobes are inserted into code an ARM instruction is replaced
by a breakpoint. When this is hit, the original instruction must be
emulated out-of-line. This patchset fixes even more bugs in the
instruction decoding and emulation.
