Subject[PATCH v4 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 v4:
- build the entire directory arch/arm/xen under arch/arm64;
- add the arm64 hypercall wrappers to arch/arm/xen/hypercall.S.


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 on ARM64
MAINTAINERS: add myself as arm64/xen maintainer
