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
