[PATCH 1/3] linux/const.h: move UL() macro to include/linux/const.h

Some architectures are duplicating the definition of UL():

  #define UL(x) _AC(x, UL)

This is not actually arch-specific, so it will be useful to move it
to a common header.  Currently, we only have the uapi variant for
linux/const.h, so I am creating include/linux/const.h.

I am also adding _UL(x), _ULL(x), ULL(x) because _AC() is used for
UL in most places (and ULL in some places).  I expect _AC(..., UL)
will be replaced with _UL(...) or UL(...).  The underscore-prefixed
one should be used for exported headers.

Note:
I renamed UL(x) in arch/m68k/mm/init.c, where it is used for a
different meaning.

Shouldn't that be a separate (prerequisite) patch?
