[PATCH v2 0/1] css: SCHIB measurement block origin must be aligned

Hi,

By testing Measurement with KVM unit tests I fall on this:
we forgot to test the alignment of the MBO for measurement format 1.

The last 6 bits of the MBO must be null, i.e. an aligned on 64 bytes
of the MBO, otherwise an operand exception is recognized when issuing
a msch instruction.

Regards,
Pierre
