s390/jump label: add missing jump_label_apply_nops() call When modules are loaded we want to transform the compile time generated nops into runtime generated nops. Otherwise the jump label sanity check will detect invalid code when trying to patch code. Fixes this crash: Jump label code mismatch at __rds_conn_create+0x3c/0x720 Found: c0 04 00 00 00 01 Expected: c0 04 00 00 00 00 Kernel panic - not syncing: Corrupted kernel text CPU: 0 PID: 10 Comm: migration/0 Not tainted 3.19.0-01935-g006610f #14 Call Trace: <0000000000113260> show_trace+0xf8/0x158) <000000000011332a> show_stack+0x6a/0xe8 <000000000069fd64> dump_stack+0x7c/0xd8 <0000000000698d54> panic+0xe4/0x288 <00000000006984c6> jump_label_bug.isra.2+0xbe/0xc001 <000000000011200c> __jump_label_transform+0x94/0xc8 Reported-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
