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.

- Fix a bug in ballooning code in PVH mode when using memory beyond
   a RAM hole in the memory map

Changes in V3:
- minor comment for patch 3 addressed

Changes in V2:
- added patch 4
- addressed comment regarding patch 3

Juergen Gross (4):
   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
   mini-os: fix bug in ballooning on PVH

Could someone please commit this series?

Done.

Samuel gave his R-b nearly 2 weeks
ago.

xen-devel is quite high volume and I don't read all the e-mails. If you need someone to commit then please CC committers@ and this will land in my inbox.

This is the reason why Wei wanted to be CC-ed for Mini-OS patches in the
past. He doesn't seem to be interested any more, unfortunately...
