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.
    
    Signed-off-by: Arnd Bergmann <arnd@...db.de>


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