[PATCH RESEND 0/2] kbuild: dead code elimination: ftrace fixes

[Marcin Nowakowski]

Enabling dead code & data elimination currently breaks ftrace operation,
as the __mcount_loc section is removed (as it is not referenced directly
anywhere in the code).
Moreover, there are a lot of entries missing in the __mcount_loc section
as the recordmcount tool doesn't currently properly handle the section
names as created by the use of -ffunction-sections.

The following 2 patches fix that behaviour.
They are based on next-20161208.

Marcin Nowakowski (2):
  kbuild: keep __mcount_loc table through dead code elimination
  recordmcount: fix mcount recording with -ffunction-sections
