[PATCH 0/3] mini-os: some memory map updates for PVH

[Juergen Gross <jgross@xxxxxxxx>]

Do some memory map related changes/fixes for PVH mode:

- Prefer the memory map delivered via start-info over the one obtained
  from the hypervisor. This is a prerequisite for Xenstore-stubdom
  live-update with rising the memory limit.

- Fix a bug related to ballooning in PVH mode: PVH Xenstore-stubdom
  can't read its target memory size from Xenstore, as this introduces
  a chicken-and-egg problem. The memory size read from the hypervisor
  OTOH includes additional "special" pages marked as reserved in the
  memory map. Those pages need to be subtracted from the read size.

Juergen Gross (3):
  mini-os: take newest version of arch-x86/hvm/start_info.h
  mini-os: prefer memory map via start_info for PVH
  mini-os: fix number of pages for PVH
