Xen devel - Feb 2009 - [PATCH 0/9] tmem: Add transcendent memory to hypervisor

This patch series implements the hypervisor portion
of transcendent memory as described at
http://oss.oracle.com/projects/tmem

Tools patches to follow.

All patches are sent as attachments as my mailer tends
to mess with attached text.  Apologies to those for
whom this is inconvenient.

Signed-off-by: Dan Magenheimer <dan.magenheimer.com>

[1] Public interface for tmem
[2] add pointer to tmem for each domain
[3] add hash.h from Linux
[4] add lzo compression files from Linux
[5] add radix-tree files from Linux with a few
    changes (documented at begin of file)
[6] interface abstractions between core tmem and xen
[7] core tmem code
[8] invocations of tmem code from existing xen code
[9] remove noisy debug message that no longer applies

Argh.  I see the attachments are even worse.  Stupid
mailer messed with them too (and I don''t recall this
being a problem before).  If you can read the
contents of the attachments, they DO contain the
correct patches.  I''ll try to make a tarball of
the patchset downloadable from somewhere, but can''t
do that until tomorrow.

Thanks to those who pointed out that the attachment
contents were fine... just the MIME type was wrong.

But if you have trouble, a tarball of the patchset can
be downloaded from here:

I forgot to add that this patchset is relative to xen-unstable
c/s 19130.  Also, here is the diffstat:
