This patch-set adds support for the new feature
'deflate-on-oom'
that has been added to the QEMU virtio memory balloon a month ago.
This feature lets a guest OS deflate balloon on OOM.
With 'deflate-on-oom' enabled virtio balloon will release
it's memory if possible right before an OOM termination of
processes.
QEMU commit with the complete feature description:

Had to update/merge in recent caps changes... Also had the same wierd
problem in domain_conf.c and qemu_command.c w/r/t 'git am -3' merging
code into wrong place...
ACK - will push shortly (this was done before freeze, but I only got to
it today...Prior version only needed minor updates... The default
setting is to not enable feature, so should be safe.)
Tks -
