["peter" <peter@perkbv.com>]

Goodmorning building the latest master of XEN

raw_copy_{to/from}_guest_*, raw_clear_guest
For the Allwinner A20 arm board XEN is giving me this error:

When i follow the tutorial for the Allwinner board
(http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Allwinner)
And checkout to: 720f45ad: Julien Grall, xen/evtchn: Fix build on ARM
XEN is working fine for me.
