[PATCH] lockdep: special s390 print_symbol() version
Have a special version of print_symbol() for s390 which clears the most significant bit of addr before calling __print_symbol(). This seems to be better than checking/changing each place in the kernel that saves an instruction pointer. Without this the output would look like: hardirqs last enabled at (30907): [<80018c6a>] 0x80018c6a hardirqs last disabled at (30908): [<8001e48c>] 0x8001e48c softirqs last enabled at (30904): [<8001dc96>] 0x8001dc96 softirqs last disabled at (30897): [<8001dc50>] 0x8001dc50 instead of this: hardirqs last enabled at (19421): [<80018c72>] cpu_idle+0x176/0x1c4 hardirqs last disabled at (19422): [<8001e494>] io_no_vtime+0xa/0x1a softirqs last enabled at (19418): [<8001dc9e>] do_softirq+0xa6/0xe8 softirqs last disabled at (19411): [<8001dc58>] do_softirq+0x60/0xe8 Acked-by: Ingo Molnar <mingo@elte.hu> Cc: Arjan van de Ven <arjan@infradead.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
