Hey Dave,
[...]
  - Two Xen hypervisor fixes:
     (1) Fix console buffer content length calculation:
           Xen changeset 26447 (x86: re-introduce map_domain_page() et
           al) once again altered virtual address space.  The current
           algorithm calculating its start could not cope with that
           change.  New version establishes this value on the base of
           image start address and is more generic.
     (2) Improve calculation of beginning of virtual address space:
           Function displaying console buffer always assumes its content
           length equal to console buffer size.  This is not true and
           sometimes it sends garbage to the screen. This patch fixes
           this issue.

Thanks. There is only one small issue. Second subject should
be linked with first comment and vice versa.
