From adb3789264c4e8567113a0e764ad30ce6e8737f3 Mon Sep 17 00:00:00 2001 From: Deng-Cheng Zhu Date: Mon, 1 Apr 2013 18:14:28 +0000 Subject: MIPS: Fix ISA level which causes secondary cache init bypassing and more The commit a96102be70 introduced set_isa() where compatible ISA info is also set aside from the one gets passed in. It means, for example, 1004K will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like the following inappropriate: if (c->isa_level == MIPS_CPU_ISA_M32R1 || c->isa_level == MIPS_CPU_ISA_M32R2 || c->isa_level == MIPS_CPU_ISA_M64R1 || c->isa_level == MIPS_CPU_ISA_M64R2) This patch fixes it.
