[Xen-devel] [PATCH v4 0/4] support linear p2m list in migrate stream v2

[Juergen Gross <jgross@xxxxxxxx>]

Add support for the virtual mapped linear p2m list of pv-domains in the
v2 migrate stream. This will allow to migrate domains larger than 512
GB.

Tested with 32- and 64-bit pv-domains both with and without linear p2m
list and with a hvm domain.

Changes in V4:
- correct format strings in patch 2 for x86-32 as requested by Ian
  Campbell
- modify commit note of patch 2 as requested by Wei Liu

Changes in V3:
- Moved defines to header file in patch 2 as requested by Andrew Cooper

Changes in V2:
- Added some sanity tests in patch 2 as suggested by Andrew Cooper
- Modified patch 3 according to Andrew Cooper's requests: rename of
  check_iteration to check_vm_state, call check_vm_state after each
  checkpoint, don't change check_vm_state hook but do the check decision
  internally
- Modified docs/features/migration.pandoc according to changes done in the
  series in patch 4 (requested by Andrew Cooper)

Juergen Gross (4):
  libxc: split mapping p2m leaves into a separate function
  libxc: support of linear p2m list for migration of pv-domains
  libxc: stop migration in case of p2m list structural changes
  libxc: set flag for support of linear p2m list in domain builder
