Needs a release exception.
Konrad,
We'd like to get some of these into 4.5 so as to ease life for people
who want to backport ARM xenaccess and/or continue developing it for
4.6.
I'm in favour of only "xen/xsm: Wrap mem_access blocks into
HAS_MEM_ACCESS ifdefs" and "xen/arm: Add p2m_set_permission and
p2m_shatter_page helpers." for now IMO, the new hypercall can/should
wait and come along with the user in 4.6.
Those two patches are a slight refactoring and a refactoring+ifdeffing
(refactorings/movements painful to rebase without introducing errors).
IMHO if they build then the risk of other regressions is slight.
Ian.
