ARM: kprobes: Decode 16-bit Thumb PUSH and POP instructions
These instructions are equivalent to
stmdb sp!,{r0-r7,lr}
ldmdb sp!,{r0-r7,pc}
and we emulate them by transforming them into the 32-bit Thumb
instructions
stmdb r9!,{r0-r7,r8}
ldmdb r9!,{r0-r7,r8}
This is simpler, and almost certainly executes faster, than writing
simulation functions.
