Jorgen Hansen a1d88436d5 VMCI: Fix two UVA mapping bugs 
(this is a resend of this patch. Originally sent last year, but post
 appears to have been lost)

This change fixes two bugs in the VMCI host driver related to mapping
the notify boolean from user space into kernel space:
- the actual UVA was rounded up to the next page boundary - resulting
  in memory corruption in the calling process whenever notifications
  would be signalled. This has been fixed by just removing the
  PAGE_ALIGN part, since get_user_pages_fast can figure this out on
  its own
- the mapped page wasn't stored anywhere, so it wasn't unmapped and
  put back when a VMCI context was destroyed. Fixed this by
  remembering the page.
