Thanks for the work in putting this together.  Just a heads up that the
split queue fails on a patch with no author/date/subject as follows:

[...]
(174/286) Applying: rt-add-rt-to-mutex-headers.patch
(175/286) Applying: rwsem-add-rt-variant.patch
(176/286) Applying: rt: Add the preempt-rt lock replacement APIs
(177/286) Patch format detection failed.
git am of percpu-rwsem-compilefix.patch failed.

Looking at percpu-rwsem-compilefix.patch -- it starts with three dashes,
so it looks like the shortlog and long-log got inadvertently thrown out,
as well as any author or optional date information, etc.

Fixing that one, I get further, until I get to:

[...]
(270/286) Applying: wait-simple: Simple waitqueue implementation
(271/286) Applying: rcutiny: Use simple waitqueue
(272/286) Patch format detection failed.
git am of treercu-use-simple-waitqueue.patch failed.

This "treercu-use-simple-waitqueue.patch" has the exact same problem.

Note that I'm using git directly, and not quilt -- which is more
strict in what it will accept, hence it catches these kinds of things.

Thanks,
Paul.
