From bbacff94d0c38163ef01361de006797c92e69e58 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Thu, 14 Oct 2010 15:09:02 -0400 Subject: arch/tile: provide a definition of MAP_STACK It's convenient for userspace (in particular, glibc) to find a definition of MAP_STACK. We use MAP_GROWSDOWN as an alias since that's appropriate for the main stack, and since our current allocation of mmap flags bits is running a bit short otherwise.
