From 52c985acf3fe95bd7b842bace8134971f0f431a2 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 31 Aug 2018 15:28:57 -0700 Subject: [PATCH] MIPS: Move arch_mem_init() comment near definition The comment describing arch_mem_init() was separated from the definition of arch_mem_init() by commit a09fc446fb6d ("[MIPS] setup.c: use early_param() for early command line parsing"). Move the comment such that it's next to the definition again for ease of reading.
