[GIT PULL] xen: core dom0 support

[Jeremy Fitzhardinge]

Hi Ingo,

This branch has the basics of Xen dom0 support.  It is not sufficient
to get a booting system (it implements no access to physical devices),
but it is enough to at least get the kernel to start and print some
console messages.

This is essentially unchanged from the last time I posted it.

The following changes since commit e7c064889606aab3569669078c69b87b2c527e72:
  Jeremy Fitzhardinge (1):
        xen: add FIX_TEXT_POKE to fixmap
