Interestingly, that 'fix' now breaks the build:

cc1: warnings being treated as errors
/home/benh/linux-powerpc-test/arch/powerpc/kernel/process.c:356: error:
'set_debug_reg_defaults' defined but not used 

This file is is becoming an absolute mess of ifdef's in large part due
to the new BookE debug stuff and your HW breakpoint stuff... Any chance
you and Shaggy see if you can improve that situation a bit ?

Cheers,
Ben.
