kernel/arch/csky/include/asm/kprobes.h, branch linux-rolling-stableHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-rolling-stable2021-10-01T01:24:06Zkprobes: treewide: Make it harder to refer kretprobe_trampoline directly2021-10-01T01:24:06ZMasami Hiramatsumhiramat@kernel.org2021-09-14T14:40:54Zurn:sha1:adf8a61a940c49fea6fab9c3865f2b69b8ceef28
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 supported2020-04-03T03:14:17ZGuo Renguoren@linux.alibaba.com2020-04-01T01:17:02Zurn:sha1:33e53ae1ce413a081254e686d9b27cc1b3585e2f
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.
