    crypto: caam - get rid of tasklet · 66d2e202
    Russell King authored
    Threaded interrupts can perform the function of the tasklet, and much
    more safely too - without races when trying to take the tasklet and
    interrupt down on device removal.
    
    With the old code, there is a window where we call tasklet_kill().  If
    the interrupt handler happens to be running on a different CPU, and
    subsequently calls tasklet_schedule(), the tasklet will be re-scheduled
    for execution.
    
    Switching to a hardirq/threadirq combination implementation avoids this,
    and it also means generic code deals with the teardown sequencing of the
    threaded and non-threaded parts.
