csky: Revert mmu ASID mechanism Current C-SKY ASID mechanism is from mips and it doesn't work well with multi-cores. ASID per core mechanism is not suitable for C-SKY SMP tlb maintain operations, eg: tlbi.vas need share the same asid in all processors and it'll invalid the tlb entry in all cores with the same asid. This patch is prepare for new ASID mechanism. Signed-off-by: Guo Ren <ren_guo@c-sky.com> Cc: Arnd Bergmann <arnd@arndb.de>
