MADV_PAGEOUT, MADV_POPULATE_READ, MADV_COLLAPSE are conditionally

So consolidate and move them all to vm_util.h, which fixes the build
failure.
An alternative approach from Muhammad Usama Anjum was: rely on "make
headers" being required, and include asm-generic/mman-common.h. This
works in the sense that it builds, but it still generates warnings about
duplicate MADV_* symbols, and the goal here is to get a fully clean (no
warnings) build here.
I've not looked in detail. But it seems like your first revision was merged
and after that my cleanup has also been merged. My cleanup patch is adding
correct header files and removing these duplicate defines: It is in
mm-stable now.
