[PATCH] net: remove superfluous call to synchronize_net()
inet_register_protosw() function is responsible for adding a new
inet protocol into a global table (inetsw[]) that is used with RCU rules.
As soon as the store of the pointer is done, other cpus might see
this new protocol in inetsw[], so we have to make sure new protocol
is ready for use. All pending memory updates should thus be committed
to memory before setting the pointer.
This is correctly done using rcu_assign_pointer()
synchronize_net() is typically used at unregister time, after
unsetting the pointer, to make sure no other cpu is still using
the object we want to dismantle. Using it at register time
is only adding an artificial delay that could hide a real bug,
and this bug could popup if/when synchronize_rcu() can proceed
faster than now.
This saves about 13 ms on boot time on a HZ=1000 8 cpus machine ;)
(4 calls to inet_register_protosw(), and about 3200 us per call)

netfilter: nf_nat: add support for persistent mappings
The removal of the SAME target accidentally removed one feature that is
not available from the normal NAT targets so far, having multi-range
mappings that use the same mapping for each connection from a single
client. The current behaviour is to choose the address from the range
based on source and destination IP, which breaks when communicating
with sites having multiple addresses that require all connections to
originate from the same IP address.
Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the
destination address is taken into account for selecting addresses.

netfilter: nf_log regression fix
commit
ca735b3aaa945626ba65a3e51145bfe4ecd9e222
'netfilter: use a linked list of loggers'
introduced an array of list_head in "struct nf_logger", but
forgot to initialize it in nf_log_register(). This resulted
in oops when calling nf_log_unregister() at module unload time.

skge_down() disables the TX queue, but then reenables it by mistake via

Fix it by moving the waking of the queue from skge_tx_clean() to the

more.
Simplify the suspend and resume callbacks of r8169 using the
observation that the PCI PM core can take care of some operations
carried out by the driver.
Additionally, make the shutdown callback of r8169 only put the device
into a low power state if the system is going to be powered off
