-Subject: [PATCH] x86/ioapic: Restore IO-APIC irq_chip retrigger callback
-
-commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de upstream.
-
-commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC
-chip and did not add it to the new IO-APIC-IR irq chip.
-
-Unfortunately the software resend fallback is not enabled on X86, so edge
-interrupts which are received during the lazy disabled state of the
-interrupt line are not retriggered and therefor lost.
-
-Restore the callbacks.
-
-[ tglx: Massaged changelog ]

-Fixes: d32932d02e18  ("x86/irq: Convert IOAPIC to use hierarchical irqdomain interfaces")
