If CONFIG_NETFILTER if not selected when compile the kernel source code, 
ipv6_getsockopt will returen an EINVAL error if optname is not supported by
the kernel. But if CONFIG_NETFILTER is selected, ENOPROTOOPT error will 
be return.

This patch fix to always return ENOPROTOOPT error if optname argument of 
ipv6_getsockopt is not supported by the kernel.

Assigning a valid random address to bridge device solves problems
when bridge device is brought up before adding real device to bridge.
When the first real device is added to the bridge, it's address
will overide the bridges random address.

Note: any device added to a bridge must already have a valid
ethernet address.

As reported by Damien Thebault, the double POSTROUTING hook invocation
fix caused outgoing packets routed between two bridges to appear without
a link-layer header. The reason for this is that we're skipping the
br_nf_post_routing hook for routed packets now and don't save the
original link layer header, but nevertheless tries to restore it on
output, causing corruption.

The root cause for this is that skb->nf_bridge has no clearly defined
lifetime and is used to indicate all kind of things, but that is
quite complicated to fix. For now simply don't touch these packets
and handle them like packets from any other device.

When copying entries to user, the kernel makes two passes through the
data, first copying all the entries, then fixing up names and counters.
On the second pass it copies the kernel and match data from userspace
to the kernel again to find the corresponding structures, expecting
that kernel pointers contained in the data are still valid.

This is obviously broken, fix by avoiding the second pass completely
and fixing names and counters while dumping the ruleset, using the
kernel-internal data structures.

This patch against 2.6.23 sparc-2.6.git contains a number of minor
cleanups of the sparc serial drivers.  Initially I fixed this build
warning:

WARNING: vmlinux.o(.text+0x107a2c): Section mismatch: reference to .init.text:add_preferred_console (between 'sunserial_console_match' and 'sunserial_console_termios')

which is done by declaring sunserial_console_match() as __init.  This
resulted in build warnings on sunserial_current_minor.  To resolve
these the variable was changed so it is no longer global, and to hide
operations on it inside 2 new functions. These functions handle the
UART minor handling code that is common to all sparc serial drivers.

These changes allowed to clean up the uart counters in all the sparc
serial drivers, and the administration of minor device numbers.

Lastly, sunserial_console_termios() does not need to be exported since
it is only called from non-modular code.

Sadly, the following build warning still exists:

WARNING: vmlinux.o(__ksymtab+0x2910): Section mismatch: reference to .init.text:sunserial_console_match (between '__ksymtab_sunserial_console_match' and '__ksymtab_sunserial_unregister_minors')

This could be resolved by not exporting sunserial_console_match(), but
this is not possible at the moment because it is being called from
modular code. On the other hand, this is a bogus warning since it
comes from a ksymtab section.

The saa7134 video driver starts dropping frames when used together with the
saa7134-alsa driver. Frames are dropped because when an audio event is waiting
the driver simply ignores the interrupt and passes it on to the saa7134-alsa
interrupt handler. The alsa interrupt handler in turn acknowledges all types
of events thus clearing the pending video events as well. Fix by only masking
out the audio event in the video interrupt handler and by only acknowledging
the audio event in the alsa driver.
