[PATCH v3 0/6] Introduce Xen support to ARM64

Hi all,
this patch series introduces Xen support to arch/arm64.

As you can see from the following patches, there is very little arm64
specific code here, basically only one assembly file
(arch/arm64/xen/hypercall.S).

Everything else is common with Xen for ARMv7, in particular the code
under arch/arm/xen (enlighten.c and the stubs in grant-table.c) and most
of the header files under arch/arm/include/asm/xen (hypercall.h,
hypervisor.h, interface.h, page.h) can be reused as-is.

Changes in v3:
- fix comment in hypercall.S to reflect the actual calling convention;
- add a patch to update the MAINTAINERS file.

Stefano Stabellini (6):
arm/xen: define xen_remap as ioremap_cached
arm64/xen: introduce asm/xen header files on arm64
arm64/xen: implement ioremap_cached on arm64
arm64/xen: use XEN_IO_PROTO_ABI_ARM on ARM64
arm64/xen: introduce CONFIG_XEN and hypercall.S on ARM64
MAINTAINERS: add myself as arm64/xen maintainer
