  s390x/helper: Remove s390_cpu_physical_memory_map (2015-02-18 09:37:15 +0100)

----------------------------------------------------------------
Features for s390x/kvm

1. guest reIPL changes (Fan Zhang)
Implements subcode 5 and 6 of diag 0x308. This allows to use
/sys/firmware/[re]ipl/ccw/* and the chreipl and lsreipl tools in
Linux. In addition to the normal "change the disk" this also
allows to switch from booting an external kernel into rebooting
from a disk.

2. Memory page table walking (Thomas Huth)
Fix several page table walking functions, used in several places
like gdb server and instruction handling. Also use these functions
in several I/O related functions.
