From: Stefano Stabellini
Date: Wed Oct 08 2014 - 09:06:05 EST

Hi all,
this patch series introduces support for GNTTABOP_cache_flush to perform
cache maintenance operation on foreign pages and reverts the current
code based on XENFEAT_grant_map_identity.

Changes in v3:
- fix the cache maintenance op call to match what Linux does natively;
- update the hypercall interface to match Xen.

Changes in v2:
- remove the definition of XENFEAT_grant_map_identity;
- update the hypercall interface to match Xen;
- call the interface on a single page at a time.

Stefano Stabellini (2):
xen/arm: remove handling of XENFEAT_grant_map_identity
xen/arm: introduce GNTTABOP_cache_flush
