[S390] sclp: Get rid of in_atomic() use.
Reintroduces in_interrupt() check in sclp_tty code. Add may_schedule parameter to vt220 write function, so we can let the write function know if it may schedule or not. So we disallow scheduling for all console calls and may allow them for tty calls. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
