Hello, This series was initially sent by Andrew on the OpenBMC list :
https://lists.ozlabs.org/pipermail/openbmc/2019-January/014640.html We had an issue with the introduction of 4451d3f59f2a ("clocksource/drivers/fttmr010: Fix set_next_event handler") in Linux where our QEMU Aspeed machine were becoming very slow. The series' approach is to provide back-pressure and it has shown significant improvement on the initial behavior which became normal again. Sorry for this last minute fix but I think it's worth merging for all the QEMU Aspeed machine. It's a bit late for QEMU-4.0 so that might be 4.1 material. Thanks, C.
