[GIT PULL] probes: Fixes for v6.7

[Masami Hiramatsu]

Hi Linus,

Probes fixes for 6.7-rc8:

- Kprobes/x86: 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.
