    ARM: 5886/1: arm: Fix cpu_proc_fin() for proc-v7.S and make kexec work · 1f667c69
    Tony Lindgren authored
    The comments in arm_machine_restart() suggest that cpu_proc_fin()
    will clean and disable cache and turn off interrupts. This does
    not seem to be implemented for proc-v7.S, implement it the same
    way as for proc-v6.S.
    
    This also makes kexec work for v7. Note that a related TLB and
    branch traget flush patch is also needed to avoid kexec
    "crc error".
    
    Note that there are still some issues that seem to be related
    to L2 cache being on and causing occasional uncompress "crc error"
    with kexec. Anyways, this gets kexec mostly working on V7 for now.
