Subject: [PATCH v3 1/4] doc,xen: document hypervisor sysfs nodes for xen
Today only a few sysfs nodes under /sys/hypervisor/ are documented
for Xen in Documentation/ABI/testing/sysfs-hypervisor-pmu.
Add the remaining Xen sysfs nodes under /sys/hypervisor/ in a new
file Documentation/ABI/stable/sysfs-hypervisor-xen and add the Xen
specific sysfs docs to the MAINTAINERS file.
Signed-off-by: Juergen Gross <jgross@...e.com>

V3:
- added hint for hidden values where appropriate (Andrew Cooper)
V2:
- rename file to Documentation/ABI/stable/sysfs-hypervisor-xen in
order to reflect Xen dependency
- leave pmu entries in old file under testing (Boris Ostrovsky)
