[Qemu-devel] [PATCH v2 00/20] [uq/master] Patch queue, part V (the rest)

[Jan Kiszka <jan.kiszka@siemens.com>]

This series catches "all the rest" to prepare QEMU's KVM support for
merging with qemu-kvm. IOW, once these bits here are applied, qemu-kvm
can switch its infrastructure to upstream and is effectively only adding
own bits for in-kernel irqchip and device assignment support.

Topics of this series are:
 - support for optimized interrupt handling by hooking cpu_interrupt
 - another preparational step for in-kernel irqchip support
 - x86: Do not leave halt if interrupts are disabled
 - mark VCPU state dirty on creation (fixed deadlock on early hw_error)
 - complete KVM support for PAT MSR, some related improvements for TCG
 - further consolidation of inner kvm_cpu_exec loop
 - expose VCPU host thread ID via "info cpus" and "query-cpus"

Changes in v2:
 - Rebased over current uq/master
 - Build fix for MAC OS (regression of previous round)
 - Fix for x86 hardware breakpoints in TCG mode (regression of previous
   round)
 - Build fix for s390 (regression of previous round)
 - Removed premature optimization from "Install optimized interrupt
   handlers"
 - Keep KVM_RUN return value in separate variable (cleanup)
 - Reorder error handling of KVM_RUN (micro-optimization)
