Subject: [PATCH v3 0/4] irq: sun4i IRQ 0 / ENMI fixes

Hi All,

Here is v3 of my sun4i IRQ 0 / ENMI fixes patch-set, changelog below:

v2:

PATCH 1/4 irq: Add handle_fasteoi_late_irq irq handler
New patch by Thomas Gleixner, adding a new irq handler with the "call eoi
after the irq-handler has run its course" behavior we need to avoid double
irqs on the ENMI.

PATCH 2/4 irqchip: sun4i: Fix irq 0 not working
Modified to avoid spurious calls to the irq 0 handler, as suggested by Maxime.

PATCH 3/4 irqchip: sun4i: Fix a comment about mask register
Added Maxime's Acked-by

PATCH 4/4 irqchip: sun4i: Use handle_fasteoi_late_irq for the
New patch switching the handler for irq 0 over to the new
handle_fasteoi_late_irq handler, thereby fixing the double interrupts issue

v3:

PATCH 1/4 irq: Add a new IRQCHIP_EOI_THREADED flag
New patch by Thomas Gleixner, replacing his "irq: Add handle_fasteoi_late_irq
irq handler" patch.

PATCH 2/4 irqchip: sun4i: Fix irq 0 not working
Added Maxime's Acked-by

PATCH 4/4 irqchip: sun4i: Don't ack IRQs != 0, fix acking of IRQ
New patch replacing my "irqchip: sun4i: Use handle_fasteoi_late_irq ..."
patch. This also drops acking for IRQ != 0. I've done both changes in
one patch to avoid regressing for IRQ 0.

Thanks for all the help to all involved.

Regards,

Hans
