Hi Guys, Linus just merged the next patches we need to backport : commit bd726c90b6b8ce87602208701b208a208e6d5600 Author: Helge Deller <deller@xxxxxx> Date: Mon Jun 19 17:34:05 2017 +0200 Allow stack to grow up to address space limit commit f4cb767d76cf7ee72f97dd76f6cfa6c76a5edc89 Author: Hugh Dickins <hughd@xxxxxxxxxx> Date: Tue Jun 20 02:10:44 2017 -0700 mm: fix new crash in unmapped_area_topdown() On top of this for 3.18, 3.16 and 3.10, Hugh provided us with fixes for my backports, and likely we'll get another update soon from Oleg since Cyrill reported a regression on a test program that's address by removing some apparently incorrect old code.
