| H A D | entry.h | 17a363dc Fri Apr 09 03:34:43 CDT 2021 Heiko Carstens <hca@linux.ibm.com> s390/traps,mm: add conditional trap handlers
Add conditional trap handlers similar to conditional system calls
(COND_SYSCALL), to reduce the number of ifdefs.
Trap handlers which may or may not exist depending on config options
are supposed to have a COND_TRAP entry, which redirects to
default_trap_handler() for non-existent trap handlers during link
time.
This allows to get rid of the secure execution trap handlers for the
!PGSTE case.
