[Xen-devel] [PATCH v2 4/6] xen: don't free percpu areas during suspend

2019-03-28 Thread Juergen Gross
Instead of freeing percpu areas during suspend and allocating them again when resuming keep them. Only free an area in case a cpu didn't come up again when resuming. It should be noted that there is a potential change in behaviour as the percpu areas are no longer zeroed out during suspend/resume.
