When a machine check is received while in SIE, it is reinjected into the guest in some cases. The respective code needs to access the sie_block, which is taken from the backed up R14. Since reinjection only occurs while we are in SIE (i.e. between the labels sie_entry and sie_leave in entry.S and thus if CIF_MCCK_GUEST is set), the backed up R14 will always contain a physical address in s390_backup_mcck_info. This currently works, because virtual and physical addresses are the same. Add phys_to_virt() to resolve the virtual-physical confusion.
