^^^^^^^^^^
Ick, I botched a trivial patch, it doesn't even apply. Updated one below
(with indentation fix as added bonus :-)
[PATCH -mm] softlockup-improve-debug-output.patch fix (v2)
kernel/softlockup.c: In function 'softlockup_tick':
kernel/softlockup.c:125: warning: 'regs' is used uninitialized in this function
is a genuine bug (will cause an oops in all probability,
or cause wrong info to be printed, if we're lucky). So let's fix the
softlockup-improve-debug-output.patch to actually work as intended.
