Merge tag 'for-linus-4.3b-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen bug fixes from David Vrabel: - Fix VM save performance regression with x86 PV guests - Make kexec work in x86 PVHVM guests (if Xen has the soft-reset ABI) - Other minor fixes. * tag 'for-linus-4.3b-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: x86/xen/p2m: hint at the last populated P2M entry x86/xen: Do not clip xen_e820_map to xen_e820_map_entries when sanitizing map x86/xen: Support kexec/kdump in HVM guests by doing a soft reset xen/x86: Don't try to write syscall-related MSRs for PV guests xen: use correct type for HYPERVISOR_memory_op()
