From c861519fcf95b2d46cb4275903423b43ae150a40 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Fri, 27 Nov 2015 19:17:01 +0100 Subject: MIPS: Fix delay loops which may be removed by GCC. GCC 4.1 and newer remove empty loops. This becomes a problem when delay loops get removed. Fixed by rewriting to user the proper Linux interface for such delays.
