    Freezer: Fix JFFS2 garbage collector freezing issue (rev. 2)
    
    Fix breakage caused by commit d5d8c5976d6adeddb8208c240460411e2198b393
    "freezer: do not send signals to kernel threads" in
    jffs2_garbage_collect_thread() that assumed it would be sent signals
    by the freezer.

    HWMON: coretemp, suspend fix
    
    It's not permitted to unregister a device after devices have been suspended.
    It causes deadlocks to appear on systems with coretemp hwmon loaded.  To avoid
    this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set
    in action.
     
    Also, in other cases it's generally too late to unregister the coretemp device
    if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE.

    Freezer: Fix APM emulation breakage
    
    The APM emulation is currently broken as a result of commit
    831441862956fffa17b9801db37e6ea1650b0f69
    "Freezer: make kernel threads nonfreezable by default"
    that removed the PF_NOFREEZE annotations from apm_ioctl() without adding
    the appropriate freezer hooks.  Fix it and remove the unnecessary variable flags
    from apm_ioctl().
    
    Special thanks to Franck Bui-Huu <vagabon.xyz@...il.com> for pointing out the
    problem.

    to resume from disk from an initrd.
