Add support for Netlogic's XLP MIPS SoC. This patch adds: * XLP processor ID in cpu_probe.c and asm/cpu.h * XLP case to asm/module.h * CPU_XLP case to mm/tlbex.c * minor change to r4k cache handling to ignore XLP secondary cache * XLP cpu overrides to mach-netlogic/cpu-feature-overrides.h Signed-off-by: Jayachandran C <jayachandranc@netlogicmicro.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2966/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
