[PATCH]PM_QOS-to-use-handle-based-requests 0/5

[mark gross]

This is a 5 patch series against linux-next-20091204 that changes pm_qos
to use a handle based access model for the kernel api.  The string
based model was shown to be slow if pm_qos parameters are updated on hot
code paths.

Most of the design changes where motivated by a patch
aili@codeaurora.org sent me, and I spent some time cleaning up the API.

Also, I couldn't resist myself in renaming the API's a bit given the fact
that the signatures changed enough that I had to touch all the pm_qos
users anyway.  I changed *requirement* to *request* in keeping with the
way PM_QOS really only does best effort.  I've felt "requirement" is too
strong a word for the way it works.

If folks would rather me do the function re-naming in a separate patch
set we can do that too.
