[PATCH v3 0/3] Fixes for IRQ subsystem
From: Yuriy Kolerov
Date: Wed Dec 28 2016 - 03:48:08 EST
First 2 patches fix potential bugs in IRQ subsystem. The third one
deprecates setting of affinity in Device Tree and moves setting of
the initial value of affinity to irq_enable() function of IRQ chip.
Changes for v3:
* Remove patch for manual setting of the global variable
irq_default_affinity to avoid messing with generic code.
* Fix 2 potential bugs.
* Use irq_enable() for setting of the initial value for
affinity in IDU.
Changes for v2:
* Set the value of irq_default_affinity to the boot CPU. It is
necessary because if an interrupt controller is connected to
IDU then set_affinity() is not called for IDU interrupts and
the real affinity of IDU does not correspond to the value
in the descriptor of IRQ (irq_default_affinity by default).
Yuriy Kolerov (3):
ARC: IRQ: Use hwirq instead of virq in mask/unmask
ARCv2: IRQ: Call entry/exit functions for chained handlers in MCIP
ARCv2: MCIP: Deprecate setting of affinity in Device Tree
