However, it didn't add a case for the protected_writeback_dcache_line. mips_dsemul() calls r4k_flush_cache_sigtramp() which in turn uses the protected_writeback_dcache_line() to flush the trampoline code back to memory. This used the wrong "cache" instruction leading to random userland crashes on non-FPU cores.
