[PATCH v15 07/10] arm64: kprobes instruction simulation support

2016-07-08 Thread David Long
From: Sandeepa Prabhu Kprobes needs simulation of instructions that cannot be stepped from a different memory location, e.g.: those instructions that uses PC-relative addressing. In simulation, the behaviour of the instruction is implemented using a copy of pt_regs. The following instruction cat
