The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags replacing it with
enable_irq_wake instead.

Is there a reason for bundling the changes in all of these subsystems
together into a single patch?


No, I understand this needs to be split. Since I was not 100% confident
about this change, I wanted LinusW to review and provide feedback and
gets things working before I can split this changes. I must have added
RFC, but usually it gets ignored :)

Sudeep
