Subject: [PATCH v3 0/2] Clear .bss for VP guests

PV guests need to have their .bss zeroed out since it is not guaranteed
to be cleared by Xen's domain builder

v3:
* Use existing macros for selecting mode-appropriate instructions/registers
* Use 32-bit registers in XOR
* Split removal of mode-selecting ifdefs into a separate patch

Boris Ostrovsky (2):
  xen/x86: Zero out .bss for PV guests
  xen/x86: Drop mode-selecting ifdefs in startup_xen()
