Some cleanups+optimizations primarily around offline_and_remove_memory(). Patch #1 drops the "unsafe unplug" feature where we might get stuck in offline_and_remove_memory() forever.
Patch #2 handles unexpected errors from offline_and_remove_memory() a bit nicer. Patch #3 handles the case where offline_and_remove_memory() failed and we want to retry later to remove a completely unplugged Linux memory block, to not have them waste memory forever. Patch #4 something I had lying around for longer, which reacts faster on config changes when unplugging memory. Cc: "Michael S.
