[PATCH v5 3/6] arm64: Kprobes with single stepping support

2015-02-17 Thread David Long
From: Sandeepa Prabhu Add support for basic kernel probes(kprobes) and jump probes (jprobes) for ARM64. Kprobes will utilize software breakpoint and single step debug exceptions supported on ARM v8. Software breakpoint is placed at the probe address to trap the kernel execution into kprobe hand
