[Xen-devel] [PATCH v5 00/15] Argo: hypervisor-mediated interdomain communication

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

Version five of this patch series:

* Changes are primarily addressing feedback from the v4 series reviews.
  Many points noted on the invididual commit posts.

* Critical sections have been shrunk, with allocations and frees
  pulled outside where possible, reordering logic within hypercall ops.

* A new ring hash function implemented, derived from the djb2 string
  hash function.

* Flags returned by the notify op have been simplified.

* Now uses a single argo boot parameter, taking a list:
  - top level boolean to enable/disable Argo
  - mac-permissive option to enable/disable wildcard rings
  - command line doc edit: no "CONFIG_ARGO" but refers to build config

* Switched to use the standard list data structures used by Xen's
  common code.

* Further removal of uses of fixed-width types.

* Added a new patch to add Argo to the MAINTAINERS file.
