[PATCH 0/2] pSeries: revert CPU unplug timeout

Posted by Daniel Henrique Barboza 3 years ago

Hi,

This series reverts the CPU hotunplug timeout mechanism that was added
during the 6.0.0 cycle. See patch 1 for the reasoning behind this
decision.

Patch 2 is a re-post of a patch that allows CPU hotunplug events to be
re-send to the guest [1], regardless of any existing hotunplug pending
state present in QEMU. This will give users a way to retry hotunplugging
CPUs without relying on unplug timeouts.
