Patches #2 and #3 have been split out of the previous version of patch #6
(which was patch #2 of the previous series). Patch #4 is not entirely
related but is useful to have in place before patch #5. Patch #5 is also
new.

Paul Durrant (6):
  domain: introduce alloc/free_shared_info() helpers...
  x86 / p2m: remove page_list check in p2m_alloc_table
  x86 / pv: do not treat PGC_extra pages as RAM when constructing dom0
  x86 / ioreq: use a MEMF_no_refcount allocation for server pages...
  mm: add 'is_special_page' macro...
  domain: use PGC_extra domheap page for shared_info
