This patch adds support for the Level-2 interrupt controller
hardware found in Broadcom Set Top Box System-on-a-Chip devices. This
interrupt controller is implemented using a single enable register.
This interrupt controller is always present on the platforms supported
by the irq-brcmstb-l2 driver, hence the reason why both are compiled
using the same Kconfig symbol.
[jac] removed the following warning:
drivers/irqchip/irq-bcm7120-l2.c: In function 'bcm7120_l2_intc_irq_handle':

The bootloader on the Netgear ReadyNAS RN102 uses Hardware BCH ECC
(strength = 4), while the pxa3xx NAND driver by default uses
Hamming ECC (strength = 1).
This patch changes the ECC mode on these machines to match that
of the bootloader and of the stock firmware. That way, it is
now possible to update the kernel from userland (e.g. using
standard tools from mtd-utils package); u-boot will happily
load and boot it.

bridge: Two small fixes to vlan filtering code.
This series corrects 2 small issues that I've ran across recently
while doing more work with vlan filtering changes.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently, it is possible to modify the vlan filter
configuration to add pvid or untagged support.
For example:
bridge vlan add vid 10 dev eth0
bridge vlan add vid 10 dev eth0 untagged pvid
The second statement will modify vlan 10 to
include untagged and pvid configuration.
However, it is currently impossible to go backwards
bridge vlan add vid 10 dev eth0 untagged pvid
bridge vlan add vid 10 dev eth0
Here nothing happens. This patch correct this so
that any modifiers not supplied are removed from
the configuration.

The bridge code checks if vlan filtering is enabled on both
ingress and egress. When the state flip happens, it
is possible for the bridge to currently be forwarding packets
and forwarding behavior becomes non-deterministic. Bridge
may drop packets on some interfaces, but not others.
This patch solves this by caching the filtered state of the
packet into skb_cb on ingress. The skb_cb is guaranteed to
not be over-written between the time packet entres bridge
forwarding path and the time it leaves it. On egress, we
can then check the cached state to see if we need to
apply filtering information.
