This is an *emergency* parachute to avoid an endless recursion and
consecutively a kernel stack overflow, should any function within some
ftrace framework cause an access fault, which calls _mcount / ftrace_caller
in return and so on. It might also call an ftrace'd function directly.

It's big endian.

Using -mprofile-kernel on early boot code not only confuses the

Changes since v1: adjusted dashes, whitespace, make checkpatch happy.
No functional changes.
Do NOT select FTRACE_WITH_REGS on ELF ABI v1 !
For C source, there's
#if defined(_CALL_ELF) _CALL_ELF == 2
Maybe there's something for Kconfig, too.
