Strange? It's the build error log.

kgdb: remove #include <linux/serial_8250.h> from kgdb.h
There's no reason kgdb.h itself needs to include the 8250 serial port
header file. So push it down to the _very_ limited number of individual
drivers that need the values in that file, and fix up the places where
people really wanted serial_core.h and platform_device.h.

And the line caused this build error is:
diff --git a/include/linux/kgdb.h b/include/linux/kgdb.h
