In the current code, arch_has_single_step() is not defined on MIPS,
that means MIPS does not support instruction single-step for user mode.

Use test_tsk_thread_flag() directly instead of test_ti_thread_flag() to

cpu_has_6k_cache and cpu_has_8k_cache have no user, r6k_cache_init()
and r8k_cache_init() are not defined for over 15 years, just remove

y placed between Scache and I/D Cache as per
core chahe, it will confuse userspace program otherwise.
Also I do think the level should be continues.
With this patch, we can see the vcache info as L2 cache
and scache info as L3 cache on the Loongson 3A3000
and 3A4000 platform.

So no need to check CPU 0 in {loongson3,bmips,octeon}_cpu_disable(),
just remove them.
