From 424e44c3ccb840c956200489c47a6295f3f6cad4 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Wed, 21 Feb 2018 15:29:03 +0000 Subject: [PATCH] MIPS: increase MAX_PHYSMEM_BITS on Loongson 3 only Commit c4617318 broke Loongson-2 support and maybe even more by increasing the value of MAX_PHYSMEM_BITS. At it is currently only needed on Loongson-3, define it conditionally. Note: this should be replace by upstream fix when available.
