[RFC][GIT PULL] bkl ftrace events + filter regex support

[Frederic Weisbecker <fweisbec@gmail.com>]

Hi everyone,

This patchset provides the support for bkl tracing, with the
support of regex in ftrace filters, so that one can easily filter
the bkl event traces per subsystem/directory/file.

Thanks,
Frederic.
