-Subject: [PATCH] AHCI: Fix threaded interrupt setup
-
-Commit 18dcf433f3de (AHCI: Optimize single IRQ interrupt processing)
-switched the single IRQ case of the AHCI driver to use threaded
-threaded interrupts.
-
-During this conversion, only the IRQF_SHARED flag was provided. The net
-effect of this in the presence of level interrupts is that the
-interrupt will not be masked during the execution of the treaded
-handler, leading to a screaming interrupt if the thread is not
-scheduled quickly enough, specially in error conditions:

-
-Not good. The culprit is a missing IRQF_ONESHOT flag, which addition
-solves the problem entierly. The number of interrupts drops radically:

-[Booting Debian Jessie to a prompt]
-Before fix:
- 88:       3562          0       GIC  88  ahci-sunxi
-After fix:
- 88:       1992          0       GIC  88  ahci-sunxi
-
-Tested on a A20 board (ahci-sunxi).
