This second round of patches focus on issues in cpus.c, primarily signal related. The highlights are - Add missing KVM_RUN continuation after I/O exits - Fix for timer signal race in KVM entry code under !CONFIG_IOTHREAD (based on Stefan's findings) - MCE signal processing under !CONFIG_IOTHREAD - Prevent abortion on multiple VCPU kicks - Fixed synchronous (ie. VCPU-issued) reset request processing Topics remaining for a third round are cleanups and refactorings of the KVM VCPU entry/exit path, MCE rework, and a few assorted cleanups. But I will wait at least until these bits here are ready for an upstream merge.
