MIPS: IP27: Remove incorrect `cpu_has_fpu' override Remove unsupported forcing of `cpu_has_fpu' to 1, which makes the `nofpu' kernel parameter non-functional, and also causes a link error: ld: arch/mips/kernel/traps.o: in function `trap_init': ./arch/mips/include/asm/msa.h:(.init.text+0x348): undefined reference to `handle_fpe' ld: ./arch/mips/include/asm/msa.h:(.init.text+0x354): undefined reference to `handle_fpe' ld: ./arch/mips/include/asm/msa.h:(.init.text+0x360): undefined reference to `handle_fpe' where the CONFIG_MIPS_FP_SUPPORT configuration option has been disabled.

MIPS: IP27: Update/restructure CPU overrides Inspired by Maciej's recent patch to update DEC cpu-feature-overrides.h, I updated IP27's as well to disable features known to not apply to the IP27 platform or the R10K-series of CPUs. Before: text data bss dec hex filename 8616648 463200 472240 9552088 91c0d8 vmlinux After: text data bss dec hex filename 8592256 471392 472240 9535888 918190 vmlinux I believe the increase in the size of the data section is for the same reasons as in the DEC patch.

MIPS: Optimize current_cpu_type() for better code. o Move current_cpu_type() to a separate header file o #ifdefing on supported CPU types lets modern GCC know that certain code in callers may be discarded ideally turning current_cpu_type() into a function returning a constant. o Use current_cpu_type() rather than direct access to struct cpuinfo_mips.

MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required. Most supported systems currently hardwire cpu_has_dsp to 0, so we also can disable support for cpu_has_dsp2 resulting in a slightly smaller kernel. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
