ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.
The semantic patch that makes this change is as follows:

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.
I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

Andrew Morton reported a build failure on sparc32, because TIPC
uses names like "struct node" and there is a like named data
structure defined in linux/node.h
This just regexp replaces "struct node*" to "struct tipc_node*"
to avoid this and any future similar problems.

This patch simplifies and speeds up TIPC's algorithm for identifying
on-node and off-node destinations that overlap a multicast name
sequence range. Rather than traversing the list of all known name
publications within the cluster, it now traverses the (potentially
much shorter) list of name publications made by the node itself, and
determines if any off-node destinations exist by comparing the sizes
of the two lists. (Since the node list must be a subset of the
cluster list, a difference in sizes means that at least one off-node
destination must exist.)

This patch ensures that TIPC's multicast message name lookup
algorithm does individualized scope checking for each published
name it examines. Previously, scope checking was only done for
the first name in a name table publication list, which could
result in incoming multicast messages being delivered to ports
publishing names with "node" scope, or not being delivered to
ports publishing names with "cluster" or "zone" scope.

This patch corrects many places where TIPC routines indicated
successful completion by returning TIPC_OK instead of 0.
(The TIPC_OK symbol has the value 0, but it should only be used
in contexts that deal with the error code field of a TIPC
message header.)

This patch ensurs that accept() returns successfully even when
the newly created socket is immediately disconnected by its peer.
Previously, accept() would fail if it was unable to pass back
the optional address info for the socket's peer before the
socket became disconnected; TIPC now allows accept() to gather
peer address information after disconnection. As a bonus, the
revised code accesses the socket's port more efficiently, without
the overhead incurred by a reference table lookup.

This patch eliminates an unneeded parameter when creating a low-level

This patch increases the "sequence gap" field of the LINK_PROTOCOL
message header from 8 bits to 13 bits (utilizing 5 previously
unused 0 bits). This ensures that the field is big enough to
indicate the loss of up to 8191 consecutive messages on the link,
thereby accommodating the current worst-case scenario of 4000
lost messages.

This patch introduces a new, out-of-range value to indicate that
a link endpoint does not have an existing session established
with its peer, eliminating the risk that the previously used
"invalid session number" value (i.e. zero) might eventually be
assigned as a valid session number and cause incorrect link
behavior.
The patch also introduces explicit bit masking when assigning a
new link session number to ensure it does not exceed 16 bits.
