[Xen-devel] [PATCH v2] Tmem cleanups/improvements for v4.8.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey!

Since v1: [https://lists.xen.org/archives/html/xen-devel/2016-09/msg03035.html]
 - Squashes some patches
 - Added Wei's Acked-by
 - Reworked some patches.

This batch of fixes slowly marches toward ripping out pieces
of code in tmem that are hard to maintain and improve on code
that was orginacally developed.

I had hoped that I would have had the migration support all
working, but it took longer than I thought to get to this
point. And it may have become a giant series too.

Anyhow please take a peek at the patches. The first
couple of them should be fairly easy. The rest are more of
squashing various subcommands in one.

Thanks!
