The use of stop_machine to replace the mask bits of the jump label branch is a very heavy-weight operation. This is in fact not necessary, the mask of the branch can simply be updated, followed by a signal processor to all the other CPUs to force them to pick up the modified instruction. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> [heiko.carstens@de.ibm.com]: Change jump_label_make_nop() so we get brcl 0,offset instead of brcl 0,0. This makes sure that only the mask part of the instruction gets changed when updated. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> |
