Paul Mundt 8b395265f8 sh: Fix fatal oops in copy_user_page() on sh4a (SH7780). ... We had a pretty interesting oops happening, where copy_user_page() was down()'ing p3map_sem[] with a bogus offset (particularly, an offset that hadn't been initialized with sema_init(), due to the mismatch between cpu_data->dcache.n_aliases and what was assumed based off of the old CACHE_ALIAS value). Luckily, spinlock debugging caught this for us, and so we drop the old hardcoded CACHE_ALIAS for sh4 completely and rely on the run-time probed cpu_data->dcache.alias_mask. This in turn gets the p3map_sem[] index right, and everything works again. While we're at it, also convert to 4-level page tables..
