[PATCH 0/3 v3] genirq: Fix IRQ threads VS cpuset

[Frederic Weisbecker]

Hi,

Here is another take after some last minutes issues reported by
Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>:

https://lore.kernel.org/all/73356b5f-ab5c-4e9e-b57f-b80981c35998@xxxxxxxxxxx/


Changes since v2:

* Fix early spurious IRQ thread wake-up (to be SOB'ed by Thomas)

* Instead of applying the affinity remotely, set PF_NO_SETAFFINITY
  early, right after kthread creation, and wait for the thread to
  apply the affinity by itself. This is to prevent from early wake-up
  to mess up with kthread_bind_mask(), as reported by
  Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>

  genirq: Fix interrupt threads affinity vs. cpuset isolated partitions
  genirq: Remove cpumask availability check on kthread affinity setting

  genirq: Prevent from early irq thread spurious wake-ups
