Currently when SELinux fails to allocate memory in
security_netlbl_sid_to_secattr() the NetLabel LSM domain field is set to
NULL which triggers the default NetLabel LSM domain mapping which may not
always be the desired mapping. This patch fixes this by returning an error
when the kernel is unable to allocate memory. This could result in more
failures on a system with heavy memory pressure but it is the "correct"
thing to do.

It turns out that checking to see if skb->sk is NULL is not a very good
indicator of a forwarded packet as some locally generated packets also have
skb->sk set to NULL. Fix this by not only checking the skb->sk field but also
the IP[6]CB(skb)->flags field for the IP[6]SKB_FORWARDED flag. While we are
at it, we are calling selinux_parse_skb() much earlier than we really should
resulting in potentially wasted cycles parsing packets for information we
might no use; so shuffle the code around a bit to fix this.

After some discussions with the Smack folks, well just Casey, I now have a
better idea of what Smack wants out of NetLabel in the future so I think it
is now safe to do some API "pruning". If another LSM comes along that
needs this functionality we can always add it back in, but I don't see any
LSMs on the horizon which might make use of these functions.
Thanks to Rami Rosen who suggested removing netlbl_cfg_cipsov4_del() back
in February 2008.

We did the right thing in a few cases but there were several areas where we
determined a packet's address family based on the socket's address family which
is not the right thing to do since we can get IPv4 packets on IPv6 sockets.
This patch fixes these problems by either taking the address family directly
from the packet.

We were doing a lot of extra work in selinux_netlbl_sock_graft() what wasn't
necessary so this patch removes that code. It also removes the redundant
second argument to selinux_netlbl_sock_setsid() which allows us to simplify a
few other functions.

Fix a few sparse warnings. One dealt with a RCU lock being held on error,
another dealt with an improper type caused by a signed/unsigned mixup while
the rest appeared to be caused by using rcu_dereference() in a
list_for_each_entry_rcu() call. The latter probably isn't a big deal, but
I derive a certain pleasure from knowing that the net/netlabel is nice and
clean.
Thanks to James Morris for pointing out the issues and demonstrating how
to run sparse.

Adapted the w83627hf_wdt.c driver to work with the w83697ug/uf chip,
found on MSI Fuzzy CX700 boards.
The method used is taken directly from the winbond datasheet and
surprisingly it differs slightly from all the other winbond watchdogs.
So far it has only been tested on the CX700 board that I have, but it
seems to work nicely.

Don't wait between submitting crypt requests for a bio unless
we are short of memory.
There are two situations when we must split an encrypted bio:
1) there are no free pages;
2) the new bio would violate underlying device restrictions
(e.g. max hw segments).
In case (2) we do not need to wait.
Add output variable to crypt_alloc_buffer() to distinguish between
these cases.

dm-raid1 is setting the 'DM_KCOPYD_IGNORE_ERROR' flag unconditionally
when assigning kcopyd work. kcopyd is responsible for copying an
assigned section of disk to one or more other disks. The
'DM_KCOPYD_IGNORE_ERROR' flag affects kcopyd in the following way:
When not set:
kcopyd will immediately stop the copy operation when an error is
encountered.
When set:
kcopyd will try to proceed regardless of errors and try to continue
copying any remaining amount.
Since dm-raid1 tracks regions of the address space that are (or
are not) in sync and it now has the ability to handle these
errors, we can safely enable this optimization. This optimization
is conditional on whether mirror error handling has been enabled.

Function dapm_mux_update_power needs enum index mux and register mask value val
as parameters, but it only has a parameter val, and uses it as both val and mux.
snd_soc_test_bits(widget->codec, e->reg, mask, val) val is register mask here,
e->texts[val] but val should be enum index mux here.

Increase the card components[] (and thus snd_card_info.components[],
too) array size from 80 to 128 chars so that more strings can be
stored. The 80 chars aren't enough for more than 2 HD-audio codecs,
and this hits an ugly snd_BUG() as reported by Wu Fegguang for HP
2230s.
The control protocol number is increased to 2.0.6 as well, in case
it matters.
