See patch 3 for details of the problem.  Other patches fix other errors found
while investigating.

Some patches committed straight from v1.  Several new patches with additional
cleanup.

Andrew Cooper (5):
  xen/version: Drop bogus return values for XENVER_platform_parameters
  xen/version: Calculate xen_capabilities_info once at boot
  xen/version: Introduce non-truncating XENVER_* subops
  xen/version: Fold build_id handling into xenver_varbuf_op()
  xen/version: Misc style fixes
