From 240ae287a189d21ea15c93bba1f774ee69e673a7 Mon Sep 17 00:00:00 2001 From: Fredrik Noring Date: Mon, 12 Nov 2018 23:16:40 +0000 Subject: [PATCH] MIPS: Default to --with-llsc for the R5900 Linux target as well The Linux kernel requires and emulates LL and SC for the R5900 too. The special --without-llsc default for the R5900 is therefore not applicable in that case. Reviewed-by: Maciej W.
