Subject: [PATCH 0/2] A couple of EL2 refcounts fixes

Hi all,

This addresses a couple of issues Will has found with the refcounting of
page-tables at EL2. Patch 01 fixes a nasty bug, and probably wants to go
in -stable. Patch 02 fixes a small inconsistency which made it harder to
find refcount-related bugs at EL2.

Feedback welcome !
