Patches 1-3 address bugs in the current frequency invariance support for x86,
including the incompatibility with cpu0 hotplug reported by Chris Wilson at
https://lore.kernel.org/lkml/[email protected]/
and the issue with CPUs that have less than 4 cores pointed out earlier
today by Like Xu at
https://lore.kernel.org/lkml/[email protected]/
Patch 4 is a minor code reorganization.
Giovanni Gherdovich (3):
x86, sched: Bail out of frequency invariance if base frequency is
unknown
x86, sched: Account for CPUs with less than 4 cores in freq.
invariance
x86, sched: Move check for CPU type to caller function
Peter Zijlstra (Intel) (1):
x86, sched: Don't enable static key when starting secondary CPUs
