via-rhine: move work from irq handler to softirq and beyond.
- Tx processing is moved from the irq handler to NAPI poll
- link events and obscure event processing is moved to its proper work queue
Locking rules undergo some changes through the driver.
- the driver offers the usual lock-free Tx path
- besides the IRQ handler, the link event task schedules the napi handler.
The driver thus adds some internal locking to prevent a loop when both
must be disabled.
- the reset task keeps being scheduled from the Tx watchdog handler, thus
with implicit Tx queue disabling. It does not need to care about irq,
only napi softirq and competing task.
- it is not worth to add a dedicated lock between {g, s}et_wol and
rhine_shutdown. It should not hurt no narrow it down a bit though.
- rhine_reset_task must keep its huge spin_lock_bh protected section due
to :
- races for the CAM registers (see rhine_vlan_rx_{add, kill}_vid)
- implicit use of napi_enable (see init_registers)
- use of the same lock for stats read / update exclusion between
napi rx processing and rhine_get_stats
- rhine_resume requires a softirq disabled section for the same reason
as rhine_reset_task
- {free, request}_irq have been replaced with IntrEnable actions in
rhine_{suspend, resume}. It is hidden behind init_registers for the
latter.

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.

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

Also by moving ip6_frag_id and dataref (both 4 bytes) next to each other we can

This patch splits the red_parms structure into two components.
One holding the RED 'constant' parameters, and one containing the

This permits a size reduction of GRED qdisc, and is a preliminary step

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.
tc qdisc add ... sfq \
flows 8000 \
depth 20 \
headdrop \
limit 20000 \
divisor 65536
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
better cache hit ratio.

cnic: Improve error recovery on bnx2x devices
When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages. As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.
To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.
Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

cancel_delayed_work is called while holding our private mutex.
There is no reason that I can see to hold the mutex during pci
shutdown, it was more just paranoia that I put the mutex_lock
around the call to e1000_down.
In a quick survey lots of drivers handle locking differently when
being called by the pci layer. The assumption here is that we
don't need the mutexes' protection in this function because
the driver could not be unloaded while in the shutdown handler
which is only called at reboot or poweroff.

ARM: 7254/1: restart: S3C24XX: move SWRST based S3C platforms to
S3C2412/S3C2416/S3C2443 use a special register to signal the reset to
the processor and used therefore the s3c24xx_reset_hook mechanism in the
s3c24xx-specific arch reset.
This patch introduces restart functions for these architectures,
moves the board files to them and removes the s3c24xx_reset_hook
infrastructure, as all users are gone.
