Jay Vosburgh said that the bond_3ad_adapter_speed_changed and
bond_3ad_adapter_duplex_changed is called with RTNL only, and
the functions will modify the port's information with no further
locking, they will not mutex against bond state machine and
incoming LACPDU which do not hold RTNL, So I add port lock to
protect the port information.

But they are not critical bugs, they exist since day one, and till
now they have never been hit and reported, because change for speed
and duplex is very rare, and will not occur critical problem.

The comments in the function is very old, cleanup the comments together.

The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.

But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
...  nud ...") does not trigger a netlink notification.  This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.

This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.

This is because we hold the rtnl_lock() before ndo_change_mtu() and try to flush
the work in netvsc_change_mtu(), in the mean time, netdev_notify_peers() may be
called from worker and also trying to hold the rtnl_lock. This will lead the
flush won't succeed forever. Solve this by not canceling and flushing the work,
this is safe because the transmission done by NETDEV_NOTIFY_PEERS was
synchronized with the netif_tx_disable() called by netvsc_change_mtu().

If a user calls 'cpupower set --perf-bias 15', the process will end with
a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi
call.  This is because the getopt_long structure currently has all of
the options as having an optional_argument when they really have a
required argument.  We change the structure to use required_argument to
match the short options and it resolves the issue.

jprobe, just do this similar to dccp_probe.

The intent was to only enable it by default for optimus, e.g. see the
runtime_idle callback. The suspend callback may be called directly, e.g.
