*	kprobes: treewide: Make it harder to refer kretprobe_trampoline directly	Masami Hiramatsu	2021-09-30	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Since now there is kretprobe_trampoline_addr() for referring the address of kretprobe trampoline code, we don't need to access kretprobe_trampoline directly. Make it harder to refer by renaming it to __kretprobe_trampoline().

*	csky: Add kprobes supported	Guo Ren	2020-04-03	1	-0/+48
	This patch enable kprobes, kretprobes, ftrace interface. It utilized software breakpoint and single step debug exceptions, instructions simulation on csky. We use USR_BKPT replace origin instruction, and the kprobe handler prepares an excutable memory slot for out-of-line execution with a copy of the original instruction being probed. Most of instructions could be executed by single-step, but some instructions need origin pc value to execute and we need software simulate these instructions.
