[PATCH v7 0/9] domain context infrastructure

[Paul Durrant <paul@xxxxxxx>]

From: Paul Durrant <pdurrant@xxxxxxxxxx>

The first 3 patches of the series are largely the same as v6 but patches
4 thru 9 are basically new (patch 7 being inherited from v6 but heavily
re-worked).
Patch 4 is cleanup work that I noticed needed doing whilst working patch 5.

Paul Durrant (9):
  xen/common: introduce a new framework for save/restore of 'domain'
    context
  xen/common/domctl: introduce XEN_DOMCTL_get/setdomaincontext
  tools/misc: add xen-domctx to present domain context
  docs/specs: add missing definitions to libxc-migration-stream
  docs / tools: specific migration v4 to include DOMAIN_CONTEXT
  tools/libxc: split restore handler handle_shared_info() functionality
  common/domain: add a domain context record for shared_info...
  x86/time: add a domain context record for tsc_info...
  tools/libxc: add DOMAIN_CONTEXT records to the migration stream...
