I'll apply it late next week as I don't need it immediately and I will be away until then. --- From e6aaee518b5e7eab735116a2ea57d538a8e26c19 Mon Sep 17 00:00:00 2001 From: James Le Cuirot <[email protected]> Date: Thu, 29 Jun 2017 22:11:49 +0100 Subject: [PATCH] profiles: Add profile-enforced global big-endian USE flag The flag is forced and masked by default and then unmasked where necessary.
