====================
Intel Wired LAN Driver Updates 2015-05-04

This series contains updates to igb, e100, e1000e and ixgbe.

Todd cleans up igb_enable_mas() since it should only be called for the
82575 silicon and has no clear return, so modify the function to void.

Jean Sacren found upon inspection that 'err' did not need to be
initialized, since it is immediately overwritten.

Alex Duyck provides two patches for e1000e, the first cleans up the
handling VLAN_HLEN as a part of max frame size.  Fixes the issue:
c751a3d5 ("e1000e: Correctly include VLAN_HLEN when changing
interface MTU").  The second fixes an issue where the driver was not
allowing jumbo frames to be enabled when CRC stripping was disabled,
however it was allowing CRC stripping to be disabled while jumbo frames
were enabled.

Jeff (me) fixes a warning found on PPC where the use of do_div() needed
to use u64 arg and not s64.

Mark provides three ixgbe patches, first to fix the Intel On-chip System
Fabric (IOSF) Sideband message interfaces, to serialize access using both
PHY bits in the SWFW_SEMAPHORE register.  Then fixes how semaphore bits
were released, since they should be released in reverse of the order that
they were taken.  Lastly updates ixgbe to use a signed type to hold
error codes, since error codes are negative, so consistently use signed
types when handling them.

v2: dropped the previous #6-#8 patches by Hiroshi Shimanoto based on
    feedback from Or Gerlitz (and David Miller) that it appears there
    needs to be further discussion on how this gets implemented.

====================
tipc: cleanup topology server

Not only function names declared in subscr.c are very confused, but
also topology server's locking policy is not designed very well, for
instance, usually leading to panic in some special corner cases.

In this series, we attempt to eliminate the confusion of function names
and simplify topology server's locking policy to solve above mentioned
issues. More importantly, the change will make relevant code easily
understandable and maintainable.

      tipc: deal with return value of tipc_conn_new callback · 90bdfcb7
      由 Ying Xue 提交于 
      Once tipc_conn_new() returns NULL, the connection should be shut
down immediately, otherwise, oops may happen due to the NULL pointer.

      tipc: adjust locking policy of subscription · a13683f2
      由 Ying Xue 提交于 
      Currently subscriber's lock protects not only subscriber's subscription
list but also all subscriptions linked into the list. However, as all
members of subscription are never changed after they are initialized,
it's unnecessary for subscription to be protected under subscriber's
lock. If the lock is used to only protect subscriber's subscription
list, the adjustment not only makes the locking policy simpler, but
also helps to avoid a deadlock which may happen once creating a
subscription is failed.

      tipc: involve reference counter for subscriber · 00bc00a9
      由 Ying Xue 提交于 
      At present subscriber's lock is used to protect the subscription list
of subscriber as well as subscriptions linked into the list. While one
or all subscriptions are deleted through iterating the list, the
subscriber's lock must be held. Meanwhile, as deletion of subscription
may happen in subscription timer's handler, the lock must be grabbed
in the function as well. When subscription's timer is terminated with
del_timer_sync() during above iteration, subscriber's lock has to be
temporarily released, otherwise, deadlock may occur. However, the
temporary release may cause the double free of a subscription as the
subscription is not disconnected from the subscription list.

Now if a reference counter is introduced to subscriber, subscription's
timer can be asynchronously stopped with del_timer(). As a result, the
issue is not only able to be fixed, but also relevant code is pretty
readable and understandable.
