Sandeepa Prabhu 39a67d49ba arm64: kprobes instruction simulation support ... 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 categories are simulated: - All branching instructions(conditional, register, and immediate) - Literal access instructions(load-literal, adr/adrp) Conditional execution is limited to branching instructions in ARM v8. If conditions at PSTATE do not match the condition fields of opcode, the instruction is effectively NOP. Thanks to Will Cohen for assorted suggested changes.
