Interrupt blacklisting in kernel 4.4 happens through a user-space
entity. The kernel APIs irq_blacklist_on(off) essentially send
a message to the user space service(irq balancer) and
therefore are not synchronous and do not guarantee that blacklisting
has actually taken effect. It will be granted with some latency
(userspace entity's processing delay).
Make blacklisting more robust by:
a) move irq (if it has been moved around after blacklist_on call
has been made and not yet honored) to the designated CPU
on IRQ reception
b) stop cpu_isolation in blacklisting mode boost API
c) modify NAPI stats to indicate blacklisting mode

In case of IPA hw version less than 3.0, only 32 bit DMA
address can be handled as it is only 32 bit compliant.
Because of this, setting DMA coherent mask of 37 when
IPA hw version is less than 3.0, crash is happening.
Do IPA version based DMA coherent mask setting such that
when IPA hw version is less than 3.0, set DMA coherent mask
as 32 only.

Disabling the interrupts and setting them as wakeup sources does
not work as expected. The pending interrupt gets trapped in sw
and kernel does not check for it before finishing the suspend.
Instead, use the suspend_noirq callback to guarantee that
wakeup messages don't get processed without rejecting the suspend.

WLAN suspend/resume feature has tight dependency on APPS platform
suspend/resume support. On new targets APPS suspend/resume is not
supported until target is feature complete. In absence of APPS
suspend/resume support testing WLAN offload features become
difficult. Add unit test framework to test WLAN suspend/resume
features using private IOCTL command by simulating APPS
suspend/resume behaviour.
Trigger WLAN suspend:
iwpriv wlan0 wlan_suspend 0 0
To resume WLAN run a ping test from access point side and very 1st
ping request unicast packet should trigger wake up.
If FW is not waking up APPS then use below command to do a manual
wake up:
Trigger WLAN resume:
iwpriv wlan0 wlan_resume 0 0
