Merge branch 'x86/urgent' into x86/core, to resolve conflict

There's a conflict between the call-depth tracking commits in x86/core:

  ee3e2469b346 ("x86/ftrace: Make it call depth tracking aware")
  36b64f101219 ("x86/ftrace: Rebalance RSB")
  eac828eaef29 ("x86/ftrace: Remove ftrace_epilogue()")

And these fixes in x86/urgent:

  883bbbffa5a4 ("ftrace,kcfi: Separate ftrace_stub() and ftrace_stub_graph()")
  b5f1fc318440 ("x86/ftrace: Remove ftrace_epilogue()")

It's non-trivial overlapping modifications - resolve them.
