and update the using functions accordingly.
Usage:
bool interrupts_enabled = are_interrupts_enabled()
Remove superfluos shift in are_interrupts_enabled().
than an integer. This removes the need for all users to mask the returned
value with 0x1 to determine interrupt status.
Expose this function externally to allow other users to check interrupt
status in a manner which will work for both cortex-A and cortex-M .
Usage:
bool disabled = get_interrupts_disabled();
This includes a generic critical section implementation. This
implementation also allow a user to start a critical section while
interrupts are already disabled.
