    Subject[PATCH] arch/x86 cpu hotplug: remove depends on CONFIG_EXPERIMENTAL
    The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
    while now and is almost always enabled by default. As agreed during the
    Linux kernel summit, remove it from any "depends on" lines in Kconfigs.
