Subject: [GIT PULL] Scope-based Resource Management for 6.5

Hi Linus,

Please consider pulling the SBRM infrastructure so that people can start
building upon it. Specifically Greg also wants to start using this soon.

Once this lands, I'll start to trickle in the conversions I've done for
the next release.

Thanks!

----------------------------------------------------------------
Scope-based Resource Management infrastructure

These are the first few patches in the Scope-based Resource Management
series that introduce the infrastructure but not any conversions as of
yet.

Adding the infrastructure now allows multiple people to start using them.

Of note is that Sparse will need some work since it doesn't yet
understand this attribute and might have decl-after-stmt issues -- but I
think that's being worked on.
