cl349@firebug.cl.cam.ac.uk e9eaa6bafb Remove support for xenbus driver subtypes since with the subtype field there's no fallback.

cl349@firebug.cl.cam.ac.uk 90562ffd56 Get rid of xenbus_uuid_to_domid - get the frontend id from the node. 
We don't want to parse paths we read out of the store to _construct_
other paths and tie down the store layout for no good reason.
Also require the frontend path to exist and be valid before creating
the device.

cl349@firebug.cl.cam.ac.uk 7f434cccbf Update probe code for backend layout. 
Backend directories are of form backend/<type>/<frontend-uuid>/<id>.
This extra level makes an asymmetry with front ends (device/type/id) and
are too long to make nice bus-ids under Linux, but the code isn't too
horrible, and an OS which only wants to be a guest doesn't need to implement
it. It allows backends to calculate the front-end path directly, which
is a nice benefit.
Also: subtype matching is tightened: they must match exactly. That way a future
variant which requires a specific driver will not match current drivers.

kaf24@firebug.cl.cam.ac.uk ba19712966 Fix Xen patches to Linux so that they use pfn_pte() and 
pfn_pte_ma() constructors, rather than splicing together

that the NX/XD bit is safely masked off on systems that do
not support it.

I don't see the problem on machine that I typically use, but I found and
fixed the problem on a big machine. It was causing a stack overflow. If
you look at the current code, it's a bit dangerous, see => part. This
patch fixes it.
