config CEPH_LIB
	tristate "Ceph core library"
	depends on INET
	select LIBCRC32C
	select CRYPTO_AES
	select CRYPTO_CBC
	select CRYPTO
	select KEYS
	default n
	help
	  Choose Y or M here to include cephlib, which provides the
	  common functionality to both the Ceph filesystem and
	  to the rados block device (rbd).

	  More information at http://ceph.newdream.net/.

	  If unsure, say N.

config CEPH_LIB_PRETTYDEBUG
	bool "Include file:line in ceph debug output"
	depends on CEPH_LIB
	default n
	help
	  If you say Y here, debug output will include a filename and
	  line to aid debugging.  This increases kernel size and slows
	  execution slightly when debug call sites are enabled (e.g.,
	  via CONFIG_DYNAMIC_DEBUG).

	  If unsure, say N.

config CEPH_LIB_USE_DNS_RESOLVER
	bool "Use in-kernel support for DNS lookup"
	depends on CEPH_LIB
	select DNS_RESOLVER
	default n
	help
	  If you say Y here, hostnames (e.g. monitor addresses) will
	  be resolved using the CONFIG_DNS_RESOLVER facility.

	  For information on how to use CONFIG_DNS_RESOLVER consult
	  Documentation/networking/dns_resolver.txt

	  If unsure, say N.

logic before the MCE CPU hotplug callback starts the timer with add_timer_on(). So the timer is already queued which triggers the BUG. Using add_timer_on() is pretty pointless in this code because the timer is strictlty per CPU, initialized as pinned and all operations which arm the timer happen on the CPU to which the timer belongs. Simplify the whole machinery by using mod_timer() instead of add_timer_on() which avoids the problem because mod_timer() can handle already queued timers. Use __start_timer() everywhere so the earliest armed expiry time is preserved.
