I messed up one of my rebases here and accidentally sent
the wrong changelog text. My intention was to have the
combined patch but with this text:

arch: include linux/cpu.h for trap_init() prototype

some architectures run into a -Wmissing-prototypes warning
for trap_init()

arch/microblaze/kernel/traps.c:21:6: warning: no previous prototype for 'trap_init' [-Wmissing-prototypes]

Include the right header to avoid this consistently, removing
the extra declarations on m68k and x86 that were added as local
workarounds already.

I made the same mistake with the "arch: add do_page_fault prototypes"
patch that was missing an explanation.
