Module Name:    src
Committed By:   jdolecek

Modified Files:
        src/sys/arch/xen/include: xen_shm.h
        src/sys/arch/xen/x86: xen_shm_machdep.c
        src/sys/arch/xen/xen: hypervisor.c xbdback_xenbus.c

Log Message:
change interface for xen_shm_map() so that caller always supplies the VA,
it now fails only if the Xen hypercall fails, in which case the failure
is final

change xbdback to pre-allocate KVA on xbdback attach (and free on detach),
so it has always KVA to map the request pages

remove no longer needed KVA allocation failure handling
