Subject[PATCH 0/4] [git pull] for tip/tracing/ftrace

Ingo,

This patch series implements copy_word_from_user. I found three open
coded locations in ftrace that implemented this. It basically allows
the kernel to read a space delimited word from user space.

This change is a nice clean up to the code. It also fixes a minor
bug that was in one of the implementations. That is, if there was
too much space between the words, it could cause another unneeded
iteration back to userspace. The result was the same, but the
implementation was not clean.

Please pull the latest tip/tracing/ftrace tree, which can be found at:
