The patch titled
lockdep: special s390 print_symbol() version
has been removed from the -mm tree. Its filename is
lockdep-special-s390-print_symbol-version.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: lockdep: special s390 print_symbol() version
From: Heiko Carstens <heiko.carstens@xxxxxxxxxx>
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 disabled at (30897): [<8001dc50>] 0x8001dc50
instead of this:
hardirqs last enabled at (19421): [<80018c72>] cpu_idle+0x176/0x1c4
