When testing diag308 subcodes 0/1 on lpar with virtual mem set up, I
experienced spec PGMs and addressing PGMs due to the tests not setting
short psw bit 12 and leaving the DAT bit on. The problem was not found
under KVM/QEMU, because Qemu just ignores all cpu mask bits.

v1 -> v2:
* Fixed comment in extra patch
* Now using pre-defined reset psw
* Fixed some comments

Janosch Frank (3):
s390x: Fix initial cr0 load comments
s390x: Add CR save area
s390x: Load reset psw on diag308 reset
