[Xen-devel] [PATCH v2] Userspace grant communication

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

Split functionality and interface changes into distinct patches.
After testing on PV, the phys_to_machine updates required to use
pages after an unmap is more complex and costly than the existing
MMU notifier method, so the new address-space remapping is only
used when we have xen_feature(XENFEAT_auto_translated_physmap).

[PATCH 1/6] xen-gntdev: Fix circular locking dependency
[PATCH 2/6] xen-gntdev: Change page limit to be global instead of per-open
[PATCH 3/6] xen-gntdev: Remove unneeded structures from grant_map tracking data
[PATCH 4/6] xen-gntdev: Use find_vma rather than iterating our vma list manually
[PATCH 5/6] xen-gntalloc: Userspace grant allocation driver
[PATCH 6/6] xen-gntdev: Introduce HVM version of gntdev
