ath9k: Fix regression in channelwidth switch at the same channel

The commit "ath9k: Fix invalid noisefloor reading due to channel update"
preserves the current channel noisefloor readings before updating
channel type at the same channel index. It is also updating the curchan
pointer. As survey updation is also referring curchan pointer to fetch
the appropriate index, which might leads to invalid memory access. This
patch partially reverts the change and stores the noise floor history
buffer before updating channel type w/o updating curchan.

Linus Torvalds [Thu, 5 Jan 2012 23:40:12 +0000 (15:40 -0800)]
vfs: fix up ENOIOCTLCMD error handling

We're doing some odd things there, which already messes up various users
(see the net/socket.c code that this removes), and it was going to add
yet more crud to the block layer because of the incorrect error code
translation.

ENOIOCTLCMD is not an error return that should be returned to user mode
from the "ioctl()" system call, but it should *not* be translated as
EINVAL ("Invalid argument").  It should be translated as ENOTTY
("Inappropriate ioctl for device").

That EINVAL confusion has apparently so permeated some code that the
block layer actually checks for it, which is sad.  We continue to do so
for now, but add a big comment about how wrong that is, and we should
remove it entirely eventually.  In the meantime, this tries to keep the
changes localized to just the EINVAL -> ENOTTY fix, and removing code
that makes it harder to do the right thing.

net: pack skb_shared_info more efficiently

nr_frags can be 8 bits since 256 is plenty of fragments. This allows it to be
packed with tx_flags.

Also by moving ip6_frag_id and dataref (both 4 bytes) next to each other we can
avoid a hole between ip6_frag_id and frag_list on 64 bit systems.

net_sched: sfq: extend limits

SFQ as implemented in Linux is very limited, with at most 127 flows
and limit of 127 packets. [ So if 127 flows are active, we have one
packet per flow ]

This patch brings to SFQ following features to cope with modern needs.

- Ability to specify a smaller per flow limit of inflight packets.
    (default value being at 127 packets)

- Ability to have up to 65408 active flows (instead of 127)

- Ability to have head drops instead of tail drops
  (to drop old packets from a flow)

Example of use : No more than 20 packets per flow, max 8000 flows, max
20000 packets in SFQ qdisc, hash table of 65536 slots.

        flows 8000 \
        depth 20 \

Ram usage :

2 bytes per hash table entry (instead of previous 1 byte/entry)
32 bytes per flow on 64bit arches, instead of 384 for QFQ, so much
