xenpaging fixes for kernel and hypervisor
Patrick,
there following patches fix xenpaging for me.
Granttable handling is incomplete. If a page is gone, a GNTST_eagain
should be returned to the caller to inidcate the hypercall has to be
retried after a while, until the page is available again.
Please review.

[PATCH v2 00/15] Consolidate the mmu notifier interval_tree and locking
From: Jason Gunthorpe <jgg at mellanox.com>
8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1,
scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where
they only use invalidate_range_start/end and immediately check the
invalidating range against some driver data structure to tell if the
driver is interested. Half of them use an interval_tree, the others
