[PATCH 0/3] irq-sim updates for 4.15

From: Bartosz Golaszewski
Date: Thu Oct 05 2017 - 08:44:58 EST

I initially submitted patch 2/3 as a standalone, but it turned out
during some development for iio that some additional functionalities
would be useful as well.

The first patch pulls in slab.h directly instead of relying on the
include from irq.h.

The second exposes an interface for accessing the base of the
allocated interrupt range.

The third implements a function that allows to map the allocated
interrupt number to the array offset within the irq sim object. This
will be later (4.16) used in iio, where for 4.15 we needed to keep the
irq base value and to calculate the offset manually in the driver.

Bartosz Golaszewski (3):
irq/irq_sim: explicitly pull in slab.h
irq/irq_sim: implement irq_sim_baseirq()
irq/irq_sim: implement irq_sim_irq2offset()
