[PATCH 00/10] ARM: ftrace: cleanups, Thumb-2, and dynamic ftrace (v2)

[Rabin Vincent]

v2: Fixes as per review comments.  The only code changes are the #error in 0004
and the removal of the #ifdef in 0009.  The rest are comments and commit
message rewording/expansion.

This series contains fixes and improvements to the ARM ftrace support.  It adds
Thumb-2 support and re-implements the dynamic ftrace support.

"ftrace: allow building without frame pointers" and "ftrace: pass KBUILD_CFLAGS
to record_mcount.pl" are non-ARM-specific ftrace patches which are required to
support the ARM functionality.

Cleanups / docs:

  ARM: ftrace: clean up mcount assembly indentation
  ARM: ftrace: document mcount formats

Thumb-2:

  ftrace: allow building without frame pointers
  ARM: ftrace: allow building without frame pointers
  ARM: ftrace: add ENDPROC annotations
  ARM: ftrace: add Thumb-2 support

Dynamic ftrace:

  ftrace: pass KBUILD_CFLAGS to record_mcount.pl
  ARM: ftrace: fix and update dynamic ftrace
  ARM: ftrace: add Thumb-2 support to dynamic ftrace
  ARM: ftrace: enable dynamic ftrace
