[Xen-devel] [PATCH RFC 00/20] Change parts of the shadow interface to be domain based

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

The purpose of this series is to prevent toolstack entry points into the
shadow code from passing d->vcpu[0] for actions which are inherenly domain
wide.  It also fixes the fact that shadow heuristics were being applied to
vcpu 0 for toolstack-initiated actions.

This series is composed mostly of mechanical changes.  The only patches which
have a practical difference on shadow execution are patches 4 and 20

The entire series has been compile tested at each changeset, for both
shadow-paging=y and n.  It has also been tested internally in XenServer, but
appears to have gotten caught up in some collateral damage from an unrelated
merge.  I am rerunning the tests.

This series can be found as in the shadow-dom-v1 branch on

  git://xenbits.xen.org/people/andrewcoop/xen.git
