[serial] BUG: spinlock bad magic on CPU#0, swapper/0
by Fengguang Wu
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.code.sf.net/p/openipmi/linux-ipmi master-ipmi-rebase
commit ccfb59efb7a78e606516ce878d8dde4690419a5f

serial: Add a polled interface to the 8250 driver
Remove the console code from the 8250 driver and add the poll code and
setup to use the console over the polled interface.
FIXME - The interactions between the 8250_early and 8250 code need to
be analyzed and tested.
