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.
