2018-02-09s390x/tcg: simplify machine check handlingDavid Hildenbrand
We currently only support CRW machine checks. This is a preparation for real floating interrupt support. Get rid of the queue and handle it via the bit INTERRUPT_MCHK. We don't rename it for now, as it will be soon gone (when moving crw machine checks into the flic). Please note that this is the same way also KVM handles it: only one instance of a machine check can be pending at a time. So no need for a queue. While at it, make sure we try to deliver only if env->cregs[14] actually indicates that CRWs are accepted. Drop two unused defines on the way (we already have PSW_MASK_...).

2018-02-09s390x/tcg: deliver multiple interrupts in a rowDavid Hildenbrand
We have to consider all deliverable interrupts. We now have to take care of the special scenario, where we first inject an interrupt with a WAIT PSW, followed by a !WAIT PSW.

2018-02-09Clean up includesMarkus Armbruster
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes, with the change to target/s390x/gen-features.c manually reverted, and blank lines around deletions collapsed.

2018-02-09Use #include "..." for our own headers, <...> for othersMarkus Armbruster
System headers should be included with <...>, our own headers with "...". Offenders tracked down with an ugly, brittle and probably buggy Perl script. Previous iteration was commit a9c94277f0. Delete inclusions of "string.h" and "strings.h" instead of fixing them to <string.h> and <strings.h>, because we always include these via osdep.h. Put the cleaned up system header includes first. While there, separate #include from file comment with exactly one blank line.

Implements the Windows Hypervisor Platform accelerator (WHPX) target. Which acts as a hypervisor accelerator for QEMU on the Windows platform. This enables QEMU much greater speed over the emulated x86_64 path's that are taken on Windows today. 1. Adds support for vPartition management. 2. Adds support for vCPU management. 3. Adds support for MMIO/PortIO. 4. Registers the WHPX ACCEL_CLASS.

2018-02-06spapr/iommu: Enable in-kernel TCE acceleration via VFIO KVM deviceAlexey Kardashevskiy
In order to enable TCE operations support in KVM, we have to inform the KVM about VFIO groups being attached to specific LIOBNs; the necessary bits are implemented already by IOMMU MR and VFIO. This defines get_attr() for the SPAPR TCE IOMMU MR which makes VFIO call the KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE ioctl and establish LIOBN-to-IOMMU link. This changes spapr_tce_set_need_vfio() to avoid TCE table reallocation if the kernel supports the TCE acceleration.
