It seems that the community have overlooked at least one issue with this code:

+static void inline __init markeins_sio_setup(void) +{ +#ifdef CONFIG_KGDB_8250
I wonder what it's doing in the Linux/MIPS patch while it's only relevant to the cross-arch KGDB patchset.

Why you #ifdef out early_serial_setup() calls is even more interesting. How this kernel is supposed to work at all with such code?!
