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 MAINTAINERS | 7 ++ arch/arm/include/asm/xen/page.h | 3 +- arch/arm/xen/hypercall.S | 98 ++++++++++++++++++++----------- arch/arm64/Kconfig | 10 +++ arch/arm64/Makefile | 1 + arch/arm64/include/asm/hypervisor.h | 6 ++ arch/arm64/include/asm/io.h | 2 + arch/arm64/include/asm/sync_bitops.h | 26 ++++++++ arch/arm64/include/asm/xen/events.h | 21 +++++++ arch/arm64/include/asm/xen/hypercall.h | 1 + arch/arm64/include/asm/xen/hypervisor.h | 1 + arch/arm64/include/asm/xen/interface.h | 1 + arch/arm64/include/asm/xen/page.h | 1 + include/xen/interface/io/protocols.h | 2 +- 14 files changed, 143 insertions(+), 37 deletions(-) create mode 100644 arch/arm64/include/asm/hypervisor.h create mode 100644 arch/arm64/include/asm/sync_bitops.h create mode 100644 arch/arm64/include/asm/xen/events.h create mode 100644 arch/arm64/include/asm/xen/hypercall.h create mode 100644 arch/arm64/include/asm/xen/hypervisor.h create mode 100644 arch/arm64/include/asm/xen/interface.h create mode 100644 arch/arm64/include/asm/xen/page.h git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen.git xen-arm64-4 - Stefano -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
