    MIPS: Don't write ones to reserved entryhi bits. · d30cecbc
    Ralf Baechle 提交于
    We've silently been relying on the hardware chopping off excess, reserved
    ASID bits for no better reason that it saving an instruction.  Because we
    already have:
    
    #define cpu_asid(cpu, mm)       (cpu_context((cpu), (mm)) & ASID_MASK)
    
    in <asm/mmu_context.h>.
    
    We can use a cleanup to avoid writing non-zero bits into the reserved
    entryhi bits.  This avoid triggering some debugging assertion in the
    Cavium simulator.
