[PATCH RFC 3/6] arm64: Kprobes instruction simulation support

2013-10-17 Thread Sandeepa Prabhu
Add support for AArch64 instruction simulation in kprobes. Kprobes need simulation of instructions that cannot be stepped right-away from different memory location. i.e. those instructions that uses PC-relative addressing. In simulation, the behaviour of the instruction is implemented using copy o
