-Subject: [PATCH] x86/ioapic: Don't let setaffinity unmask threaded EOI
- interrupt too early
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.17-rt9.tar.xz
-
-There is an issue with threaded interrupts which are marked ONESHOT
-and using the fasteoi handler.
-
-    if (IS_ONESHOT())
-        mask_irq();
-
-    ....
-    ....
-
-    cond_unmask_eoi_irq()
-        chip->irq_eoi();
-
-So if setaffinity is pending then the interrupt will be moved and then
-unmasked, which is wrong as it should be kept masked up to the point where
-the threaded handler finished. It's not a real problem, the interrupt will
-just be able to fire before the threaded handler has finished, though the irq
-masked state will be wrong for a bit.
-
-The patch below should cure the issue. It also renames the horribly
-misnomed functions so it becomes clear what they are supposed to do.
