Merge tag 'probes-fixes-v6.7-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull kprobes/x86 fix from Masami Hiramatsu:
- Fix to emulate indirect call which size is not 5 byte.
Current code expects the indirect call instructions are 5 bytes, but
that is incorrect. Usually indirect call based on register is shorter
than that, thus the emulation causes a kernel crash by accessing
wrong instruction boundary. This uses the instruction size to
calculate the return address correctly.
