single CPU vs such which are affine to only one CPU, mark per-cpu workqueue threads as such and make sure that marking "survives" CPU hotplug. Fix CPU hotplug issues with such kthreads. - A fix to not push away tasks on CPUs coming online. - Have workqueue CPU hotplug code use cpu_possible_mask when breaking affinity on CPU offlining so that pending workers can finish on newly arrived onlined CPUs too. - Dump tasks which haven't vacated a CPU which is currently being unplugged. - Register a special scale invariance callback which gets called on resume from RAM to read out APERF/MPERF after resume and thus make the schedutil scaling governor more precise. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmANYCAACgkQEsHwGGHe VUo+OBAAjfqkijDlXiGX6lrT5gRx5NZICpeMgbWa7J13XHT1ysD/b0fMGFIUyF6k aszDLTl8U/S1/qGAYlzTSPAFcdZ+ENiFqQ48ozMk4jZC3p0quHTjs/PdiSG6kYBi +e4smht+bSyLKxsG8hN0kJ+mLEd+uIQ13kP4YkxPgWbJ9WNP/U6HHGBo0rBchtSe Kn6bdd8CfwmC6rSazp7kdQoFoWeQaoMI1ODX3VphK1GtL1wq8WSICzRhpg3caeyG 3lCIddoNW9mCA9Nkc6R6HeV3uW9JGkPAjnmtTIEHDbg9pib7xNT978ieTQuqNDCi DlAHDGumzoaiVJZhD/1fj/RXMJr2YUHxtrXWNsXpiKJ9g8Tn+WC0UW/4+Mx2L/km 0RSoXJlMs1fGopS2I/fObZ6RPhmg4D+gJsMCdaHQzX4NgxZAGhNNPxMckZ0IM8A0 2NNXSHUZHVTHeJEW0E/glOcpWb5hG+vDwiBMNEWfTwYpTfrw2EEOZaKniZE7WlSL 4ItM9rkLGl1KToJzAH4A0oUtSy3vtSCo8B1noGlc09Lj+oCIBlr81z9+C79a2oxG qE7Xd4X7y7Qs3JeCbRZWQa7/2Kf1v4XnjELrJJeCZC85r0ZqJDwRX8w7lkmW2XPU m4J2prr/DDZSqrRh23/xC1fsU+vcBKSfKUFKAH4Lg2VIaUfSUEk= =2DAF -----END PGP SIGNATURE----- Merge tag 'sched_urgent_for_v5.11_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fixes from Borislav Petkov: - Correct the marking of kthreads which are supposed to run on a specific, single CPU vs such which are affine to only one CPU, mark per-cpu workqueue threads as such and make sure that marking "survives" CPU hotplug.
