[Xen-devel] [PATCH 1/4] xen: I/O Resource Accountant - Support Files

[Ryan <hap9@xxxxxxxxxxxxxx>]

This patch modifies the Makefiles to compile in the new code added in
the other patches. The rangesets were modified to support atomic moves
of ranges (so that a resource could be moved from one rangeset to
another without worry that a memory allocation might fail and leave a
range of resources untracked). In addition, Linux's red-black tree
implementation has been imported for use in reference counting pages of
I/O memory (are there any issues with copying Linux code directly into
Xen? I thought it would be ok since it looks like it has been done in
other places).
