    sparc: Remove BKL from apc · 49ab972a

    commit ab772027 (sparc: arch/sparc/kernel/apc.c to unlocked_ioctl)
    added lock/unlock_kernel() to the apc ioctl code.
    
    The code needs no serialization at all. Neither put/get_user nor the
    read/write access to the sbus devices require it. Remove BKL.
    
    cycle_kernel_lock() was added during the big BKL pushdown. It should
    ensure the serializiation against driver init code. In this case there
    is nothing to serialize. Remove it as well.
