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

From: Boris Ostrovsky
Date: Thu Feb 25 2016 - 10:17:32 EST

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

* 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()
