Changes in v7:
* Added patch 7 to prevent passing CR4's PCE bit to the hypervisor.
* Replaced WARN_ONCE()s with pr_warn_once() since stacks/registers are not
especially interesting at those sites (and because other places use pr_()
routines too) (patches 3 and 6)
* Made xensyms_next_sym return proper error code (patch 1)
* Dropped perf_unregister_guest_info_callbacks in xen_pmu_init()'s error path
since it's unsafe (patch 3)
* A few small style corrections (patch 3 mostly)
Changes in v6:
* Fix ARM builds (as suggested by Julien):
o Make XEN_SYMS depend on X86 (patch 1)
o Add CONFIG_XEN_HAVE_PVMMU and use it in drivers/xen/sys-hypervisor.c
(patch 2)
* Adjust release dates in Documentation/ABI/testing/sysfs-hypervisor-pmu
(patch 2)
