Not "lost on old systems", changing that to "not present on old systems"

ok, I'll try keeping the  include/uapi/asm-generic/mman.h and
arch/alpha/include/uapi/asm/mman.h with just what you added, so that at
least the .c files appears as using the headers were those things are
defined in the kernel sources.

Ah, and good eyes in realizing this is not the same value for all
arches!
