SubjectRe: [PATCH] add asm-generic/mman.h
Quoting r. Badari Pulavarty <pbadari@us.ibm.com>:
> MS_SYNC should be 4
> MS_INVALIDATE should be 2

Good catch, thanks!
Other numbers look right, dont they?

---

Make new MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK consistent across all arches.
The idea is to make it possible to use them portably even before distros
include them in libc headers.

Move common flags to asm-generic/mman.h
