Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

providing multiple PM domains (e.g. power controllers), but can be any value
as specified by device tree binding documentation of particular provider.
Optional properties:
- power-domains : A phandle and PM domain specifier as defined by bindings of
the power controller specified by phandle.
Some power domains might be powered from another power domain (or have
other hardware specific dependencies). For representing such dependency
a standard PM domain consumer binding is used. When provided, all domains
created by the given provider should be subdomains of the domain
specified by this binding. More details about power domain specifier are
available in the next section.
Example:
power: power-controller@12340000 {

The node above defines a power controller that is a PM domain provider and
expects one cell as its phandle argument.
Example 2:
parent: power-controller@12340000 {
compatible = "foo,power-controller";
reg = <0x12340000 0x1000>;

The nodes above define two power controllers: 'parent' and 'child'.
Domains created by the 'child' power controller are subdomains of '0' power
domain provided by the 'parent' power controller.

- atmel,disable : Should be present if you want to disable the watchdog.
- atmel,idle-halt : Should be present if you want to stop the watchdog when
entering idle state.
CAUTION: This property should be used with care, it actually makes the
watchdog not counting when the CPU is in idle state, therefore the
watchdog reset time depends on mean CPU usage and will not reset at all
if the CPU stop working while it is in idle state, which is probably
not what you want.
- atmel,dbg-halt : Should be present if you want to stop the watchdog when
entering debug state.
