From 1091bfa20b94ba14a3c8a3eaf3a5b9d3df975da2 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 3 Feb 2016 03:26:38 +0000 Subject: [PATCH] MIPS: Add P6600 cases to CPU switch statements Add cases supporting the P6600 CPU to various switch statements in core MIPS kernel code that define behaviour dependent upon the CPU.
