[Qemu-devel] [PATCH 0/8] Make icount thread-safe |

This series moves the icount state under the same seqlock as the "normal"
vm_clock implementation.
It is not yet 100% thread-safe, because the CPU list should be moved
under RCU protection (due to the call to !all_cpu_threads_idle()
in qemu_clock_warp). However it is a substantial step forward, the
only uncovered case being CPU hotplug.
Please review.

Paolo Bonzini (8):
timers: extract timer_mod_ns_locked and timerlist_rearm
timers: add timer_mod_anticipate and timer_mod_anticipate_ns
timers: use cpu_get_icount() directly
timers: reorganize icount_warp_rt
timers: prepare the code for future races in calling qemu_clock_warp
timers: introduce cpu_get_clock_locked
timers: document (future) locking rules for icount
timers: make icount thread-safe
