This change reverts commit 5e33579a6a ("devfreq: Do not allow tunable
updates when device is suspended") and commit db4f4a0933 ("PM/devfreq:
Do not switch governors from sysfs when device is suspended").
Userspace updates to sysfs nodes like governor and polling_interval are
currently not allowed when there is a non-zero suspend count. This
requirement existed in the past due to hardware dependencies in some
devfreq drivers. However, these hardware dependencies should be handled
by the relevant devfreq drivers rather than the devfreq framework so
remove the suspend count checks in these devfreq framework sysfs APIs.

Updating the zone watermarks by any means, like extra_free_kbytes,
min_free_kbytes, water_mark_scale_factor, when boost_watermark(zone) is
set can result into the higher water_mark_low|min as the macro
min_wmark_pages returns by adding the zone->watermark_boost.
Set this to Zero early.

Rely on LMK to reclaim memory and avoid OOM, when out of memory
condition is detected in a pagefault.
pagefault_out_of_memory() may be called due to commit d1b75390beb8 ("mm:
reduce the time spend by killed tasks in alloc path"), which bails out from
alloc_pages_slowpath() if the current task has been killed.

Enable the reaping of memory on a sigkill by default. This helps in
faster releasing of memory pages to buddy.

If a userspace low memory killer is present, the kernel oom killer
is not expected to be invoked. Therefore, trigger a reset on any
such occurrence.

Accessing some of the memory of the device while the device is
resetting or suspending may cause unexpected error as the HW is still
not in a stable state. Prevent this access to guarantee successful
read/write memory operations.

EDAC provides a mechanism to poll for errors using a callback function
and uses a delayed timer to schedule it. Provide an option to create
a deferrable timer if the error checking is not worth waking up
the cpu from idle.
