Merge tag 'stable/for-linus-4.1-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen features and fixes from David Vrabel: - use a single source list of hypercalls, generating other tables etc. at build time. - add a "Xen PV" APIC driver to support >255 VCPUs in PV guests. - significant performance improve to guest save/restore/migration. - scsiback/front save/restore support. - infrastructure for multi-page xenbus rings. - misc fixes. * tag 'stable/for-linus-4.1-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/pci: Try harder to get PXM information for Xen xenbus_client: Extend interface to support multi-page ring xen-pciback: also support disabling of bus-mastering and memory-write-invalidate xen: support suspend/resume in pvscsi frontend xen: scsiback: add LUN of restored domain xen-scsiback: define a pr_fmt macro with xen-pvscsi xen/mce: fix up xen_late_init_mcelog() error handling xen/privcmd: improve performance of MMAPBATCH_V2 xen: unify foreign GFN map/unmap for auto-xlated physmap guests x86/xen/apic: WARN with details. x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs xen/pciback: Don't print scary messages when unsupported by hypervisor. xen: use generated hypercall symbols in arch/x86/xen/xen-head.S xen: use generated hypervisor symbols in arch/x86/xen/trace.c xen: synchronize include/xen/interface/xen.h with xen xen: build infrastructure for generating hypercall depending symbols xen: balloon: Use static attribute groups for sysfs entries xen: pcpu: Use static attribute groups for sysfs entry
