[Xen-devel] [PATCH 0/2] Remaining ARM cross compile patches

[Ian Campbell <Ian.Campbell@xxxxxxxxxx>]

One of these got missed somehow when I put the xenctx series together.
The other is new and fixes cross compiling the arm64 hypervisor in the
environment described at
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling

There is one remaining wrinkle which is this libc bug:
https://bugs.launchpad.net/linaro-aarch64/+bug/1169164

Which can be worked around with:
diff --git a/xen/include/public/arch-arm.h b/xen/include/public/arch-arm.h
