However, adding this code and wonderful and all but why do we need to
add it?  Changelog should say why.

Okay changelog updated to:

    powerpc/boot: Add extended precision shifts to the boot wrapper.
    
    The upcoming currituck patches will need to do 64-bit shifts which will
    fail with undefined symbol without this patch.
    
    I looked at linking against libgcc but we can't guarantee that libgcc
    was compiled with soft-float.  Also Using ../lib/div64.S or
    ../kernel/misc_32.S, this will break the build as the .o's need to be
    built with different flags for the bootwrapper vs the kernel.  So for
    now the easiest option is to just copy code from
    arch/powerpc/kernel/misc_32.S  I don't think this code changes too often ;P
