Most of the QEMU changes for PV are related to the new IPL type with
subcodes 8 - 10 and the execution of the necessary Ultravisor calls to
IPL secure guests. Note that we can only boot into secure mode from
normal mode, i.e. stfle 161 is not active in secure mode.
The other changes related to data gathering for emulation and
disabling addressing checks in secure mode, as well as CPU resets.
While working on this I sprinkled in some cleanups, as we sometimes
significantly increase line count of some functions and they got
unreadable.
Janosch Frank (15):
s390x: Cleanup cpu resets
s390x: Beautify diag308 handling
s390x: protvirt: Add diag308 subcodes 8 - 10
Header sync protvirt
s390x: protvirt: Sync PV state
s390x: protvirt: Support unpack facility
s390x: protvirt: Handle diag 308 subcodes 0,1,3,4
s390x: protvirt: KVM intercept changes
s390x: protvirt: SCLP interpretation
s390x: protvirt: Add new VCPU reset functions
RFC: s390x: Exit on vcpu reset error
s390x: protvirt: Set guest IPL PSW
s390x: protvirt: Move diag 308 data over SIDAD
s390x: protvirt: Disable address checks for PV guest IO emulation
s390x: protvirt: Handle SIGP store status correctly
