Bearer list defined as a global variable is used to store bearer
instances. When tipc supports net namespace, bearers created in
one namespace must be isolated with others allocated in other
namespaces, which requires us that the bearer list(bearer_list)
must be moved to tipc_net structure. As a result, a net namespace
pointer has to be passed to functions which access the bearer list.

Global variables associated with node table are below:
- node table list (node_htable)
- node hash table list (tipc_node_list)
- node table lock (node_list_lock)
- node number counter (tipc_num_nodes)
- node link number counter (tipc_num_links)

To make node table support namespace, above global variables must be
moved to tipc_net structure in order to keep secret for different
namespaces. As a consequence, these variables are allocated and
initialized when namespace is created, and deallocated when namespace
is destroyed. After the change, functions associated with these
variables have to utilize a namespace pointer to access them. So
adding namespace pointer as a parameter of these functions is the
major change made in the commit.

In order to make tipc socket table aware of namespace, a networking
namespace instance must be passed to tipc_sk_lookup(), allowing it
to look up tipc socket instance with a given port ID from a concrete
socket table. However, as now tipc_sk_timeout() only has one port ID
parameter and is not namespace aware, it's unable to obtain a correct
socket instance through tipc_sk_lookup() just with a port ID,
especially after namespace is completely supported.

If port ID is replaced with socket instance as tipc_sk_timeout()'s
parameter, it's unnecessary to look up socket table. But as the timer
handler - tipc_sk_timeout() is run asynchronously, socket reference
must be held before its timer is launched, and must be carefully
checked to identify whether the socket reference needs to be put or
not when its timer is terminated.

In commit 58dc55f2 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.

In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.

In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.

Fix sti drivers whcih mix reg address spaces

A V2 of this old series incorporating Arnd and Lees Feedback form v1.

Following on from Arnds comments about the picophy driver here
https://lkml.org/lkml/2014/11/13/161, this series fixes the
remaining upstreamed drivers for STI, which are mixing address spaces
in the reg property. We do this in a way similar to the keystone
and bcm7445 platforms, by having sysconfig phandle/ offset pair
(where only one register is required). Or phandle / integer array
where multiple offsets in the same bank are needed).

This series breaks DT compatability! But the platform support
is WIP and only being used by the few developers who are upstreaming
support for it. I've made each change to the driver / dt doc / dt
