[Xen-devel] [PATCH 0 of 2] Virq for low memory conditions, V5

[Andres Lagar-Cavilla <andres@xxxxxxxxxxxxxxxx>]

Changes from previous posting, dated Feb 29th
- Added consideration for tmem-freeable pages before firing the virq
- Added Acked-by Ian Jackson for dom0 helper demo code
- Added .gitignore rune

Changes from V3 posted Feb 28th
- lowmemd is now xen-lowmemd
- .hgignore rune added for xen-lowmemd
- User can specify zero on the command line to disable the virq altogether
- Addressed two comments from Jan Beulich
+ Better detection of no user-provided command line threshold
+ Deal with the case in which the threshold may end up being zero.

Patch 1 is hypervisor (xen/common bits), patch 2 is tools.
