net: Add saddr op to l3mdev and vrf
First 2 patches are re-sends of patches that got lost in the ethosphere
Tuesday; they were part of the first round of l3mdev conversions.
Next 3 handle the source address lookup for raw and datagram sockets
bound to a VRF device.
The conversion to the get_saddr op also fixes locally originated TCP
packets showing up at the VRF device. The use of the FLOWI_FLAG_L3MDEV_SRC
flag in ip_route_connect_init was causing locally generated packets
to skip the VRF device.

This enables eTSEC's filer (Rx parser) and the FGPI Rx
interrupt (Filer General Purpose Interrupt) as a wakeup
source event.
Upon entering suspend state, the eTSEC filer is given
a rule to match incoming L2 unicast packets. A packet
matching the rule will be enqueued in the Rx ring and
a FGPI Rx interrupt will be asserted by the filer to
wakeup the system. Other packet types will be dropped.
On resume the filer table is restored to the content
before entering suspend state.
The set of rules from gfar_filer_config_wol() could be
extended to implement other WoL capabilities as well.
The "fsl,wake-on-filer" DT binding enables this capability
on certain platforms that feature the necessary power
management infrastructure, targeting mainly printing and
imaging applications.

switch_mm performs some checks to try and avoid entering the ASID
allocator:
(1) If we're switching to the init_mm (no user mappings), then simply
set a reserved TTBR0 value with no page table (the zero page)
(2) If prev == next *and* the mm_cpumask indicates that we've run on
this CPU before, then we can skip the allocator.
However, there is plenty of redundancy here. With the new ASID allocator,
if prev == next, then we know that our ASID is valid and do not need to
worry about re-allocation. Consequently, we can drop the mm_cpumask check
in (2) and move the prev == next check before the init_mm check, since
if prev == next == init_mm then there's nothing to do.

Our current switch_mm implementation suffers from a number of problems:
(1) The ASID allocator relies on IPIs to synchronise the CPUs on a
rollover event
(2) Because of (1), we cannot allocate ASIDs with interrupts disabled
and therefore make use of a TIF_SWITCH_MM flag to postpone the
actual switch to finish_arch_post_lock_switch
(3) We run context switch with a reserved (invalid) TTBR0 value, even
though the ASID and pgd are updated atomically
(4) We take a global spinlock (cpu_asid_lock) during context-switch
(5) We use h/w broadcast TLB operations when they are not required
(e.g. in flush_context)
This patch addresses these problems by rewriting the ASID algorithm to
match the bitmap-based arch/arm/ implementation more closely. This in
turn allows us to remove much of the complications surrounding switch_mm,
including the ugly thread flag.

Anjali fixes an issue from Dan Carpenter <dan.carpenter@oracle.com>,

locked portion insert a sanity check to ensure we are working with safe
register values.
Mitch fixes an issue where under certain circumstances, we can get an
extra VF_RESOURCES message from the PF driver at runtime. When this
occurs, we need to parse it because our VSI may have changed and that
will affect the relationship with the PF driver. But this parsing also
blows away our current MAC address, so resolve the issue by restoring
the current MAC address from the netdev struct after we parse the
resource message.
