However, that was being done in .c files, and a new build failure came up that would have been automatically avoided had these been in a common header file. 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.
