Preinitialize the program check table, so we can put it into the read-only data section. Also use only four byte entries for the table, since each program check handler resides within the first 2GB. Therefore this reduces the size of the table by 50% on 64 bit builds. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
