O-Subject: [RHEL-8.0 qemu-kvm v2 PATCH 2/2] hw/s390x: Fix bad mask in time2tod()

|
Since "s390x/tcg: avoid overflows in time2tod/tod2time", the
|
|
time2tod() function tries to deal with the 9 uppermost bits in the
|
|
time value, but uses the wrong mask for this: 0xff80000000000000 should
|
|
be used instead of 0xff10000000000000 here.
