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.
