e88a0faae5 xen: unitialised return value in xenbus_write_transaction
The return value of xenbus_write_transaction can be uninitialised in
the success case leading to the userspace xenstore utilities failing.

1107ba885e xen: add xenfs to allow usermode <-> Xen interaction
The xenfs filesystem exports various interfaces to usermode.  Initially
this exports a file to allow usermode to interact with xenbus/xenstore.

Traditionally this appeared in /proc/xen.  Rather than extending procfs,
this patch adds a backward-compat mountpoint on /proc/xen, and provides
a xenfs filesystem which can be mounted there.
