What is the change?
- This reverts commit 474d4c3249
Why do we need this change?
- This commit was added because Cortex-M didn't have a valid
stack to make required functionality work however,
the previous commit fixes this and makes interrupt stack
available for use. This removes Arm specific limitation from
these generic APIs so revert the commit to reflect the same.
