Message

Try to make the arm64 ftrace with regs merged.
The later two patches are from Torsten.
The whole series applies cleanly on v5.3-rc5

Jisheng Zhang (1):
  ftrace: introdue ftrace_call_init

Torsten Duwe (2):
  arm64: implement ftrace with regs
  arm64: use -fpatchable-function-entry if available
