Hi,

these psr bits are not fully virtualized and the current usage is not
clear (at least to me):

sp (secure performance monitor): I don't know how it is currently used by
  xenoprofile.  Isaku have you any tips on it ?

di (disable instruction set transition): should it be hard-coded to 1 or
 should it be settable by the kernel ?

si (secure interval timer): should be forced to 0?

is (instruction set): same use as di.

mc (machine check): should be forced to 1?

vm: should be forced to 0.

Comments are welcome!
Tristan.
