Pull scheduler fixes from Ingo Molnar: "Misc fixes: - an uclamp accounting fix - three frequency invariance fixes and a readability improvement" * tag 'sched-urgent-2020-04-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/core: Fix reset-on-fork from RT with uclamp x86, sched: Move check for CPU type to caller function x86, sched: Don't enable static key when starting secondary CPUs x86, sched: Account for CPUs with less than 4 cores in freq. invariance x86, sched: Bail out of frequency invariance if base frequency is unknown
