Enable some paravirtualization debugging

In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Currently deliberately clobbers regs which are allowed to be
clobbered in inlined paravirt hooks, even in native mode.
If turning this off solves a problem, then DISABLE_INTERRUPTS() or
ENABLE_INTERRUPTS() is lying about what registers can be clobbered.
