Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20180209' into staging
s390x updates: - rework interrupt handling for tcg, smp is now considered non-experimental - some general improvements in the flic - improvements in the pci code, and wiring it up in tcg - add PTFF subfunctions for multiple-epoch to the cpu model - maintainership updates - various other fixes and improvements # gpg: Signature made Fri 09 Feb 2018 09:04:34 GMT # gpg: using RSA key DECF6B93C6F02FAF # gpg: Good signature from "Cornelia Huck <conny@cornelia-huck.de>" # gpg: aka "Cornelia Huck <huckc@linux.vnet.ibm.com>" # gpg: aka "Cornelia Huck <cornelia.huck@de.ibm.com>" # gpg: aka "Cornelia Huck <cohuck@kernel.org>" # gpg: aka "Cornelia Huck <cohuck@redhat.com>" # Primary key fingerprint: C3D0 D66D C362 4FF6 A8C0 18CE DECF 6B93 C6F0 2FAF * remotes/cohuck/tags/s390x-20180209: (29 commits) MAINTAINERS: add David as additional tcg/s390 maintainer MAINTAINERS: reorganize s390-ccw bios maintainership MAINTAINERS: add myself as overall s390x maintainer s390x/pci: use the right pal and pba in reg_ioat() s390x/pci: fixup global refresh s390x/pci: fixup the code walking IOMMU tables s390x/cpumodel: model PTFF subfunctions for Multiple-epoch facility s390x/cpumodel: allow zpci features in qemu model s390x/tcg: wire up pci instructions s390x/sclp: fix event mask handling s390x/flic: cache the common flic class in a central function s390x/kvm: cache the kvm flic in a central function s390x/tcg: cache the qemu flic in a central function configure: s390x supports mttcg now s390x/tcg: remove SMP warning s390x/tcg: STSI overhaul s390x: fix size + content of STSI blocks s390x/flic: optimize CPU wakeup for TCG s390x/flic: implement qemu_s390_clear_io_flic() s390x/tcg: implement TEST PENDING INTERRUPTION ...
