ARM kprobes: core code
This is a full implementation of Kprobes including Jprobes and Kretprobes support. This ARM implementation does not follow the usual kprobes double- exception model. The traditional model is where the initial kprobes breakpoint calls kprobe_handler(), which returns from exception to execute the instruction in its original context, then immediately re-enters after a second breakpoint (or single-stepping exception) into post_kprobe_handler(), each time the probe is hit.. The ARM implementation only executes one kprobes exception per hit, so no post_kprobe_handler() phase. All side-effects from the kprobe'd instruction are resolved before returning from the initial exception. As a result, all instructions are _always_ effectively boosted regardless of the type of instruction, and even regardless of whether or not there is a post-handler for the probe.
