Please check if the appended patch helps.
It does, I am able to build a big endian MIPS kernel now. Can you notify
me if you submit this patch ?
Thanks, Roland.
Thanks,
Rafael

Subject: MIPS: Convert i8259.c to using syscore_ops
The code in arch/mips/kernel/i8259.c still hasn't been converted to
using struct syscore_ops instead of a sysdev for resume and shutdown.
As a result, this code doesn't build any more after suspend, resume
and shutdown callbacks have been removed from struct sysdev_class.
Fix this problem by converting i8259.c to using syscore_ops.
