When SPI write of odd length is requested, p54spi_write splits it
into two parts: one for all data, except the last byte, and one
for last byte and padding byte. Unfortunately, the length of
first part is not amended. It works because all meaningful bytes
have proper value and the last byte of odd length SPI write
transaction is ignored.

The previous implementation was moving back to NETWORK SLEEP state
immediately after receiving a Beacon frame. This means that we are
unlikely to receive all the buffered broadcast/multicast frames that
would be sent after DTIM Beacon frames. Fix this by parsing the Beacon
frame and remaining awake, if needed, to receive the buffered
broadcast/multicast frames. The last buffered frame will trigger the
move back into NETWORK SLEEP state.
If the last broadcast/multicast frame is not received properly (or if
the AP fails to send it), the next Beacon frame will work as a backup
trigger for returning into NETWORK SLEEP.
A new debug type, PS (debug=0x800 module parameter), is added to make
it easier to debug potential power save issues in the
future. Currently, this is only used for the Beacon frame and buffered
broadcast/multicast receiving.

We are not correctly listening to the regulatory max bandwidth
settings. To actually make use of it we need to redesign things
a bit. This patch does the work for that. We do this to so we
can obey to regulatory rules accordingly for use of HT40.
We end up dealing with HT40 by having two passes for each channel.
The first check will see if a 20 MHz channel fits into the channel's
center freq on a given frequency range. We check for a 20 MHz
banwidth channel as that is the maximum an individual channel
will use, at least for now. The first pass will go ahead and
check if the regulatory rule for that given center of frequency
allows 40 MHz bandwidths and we use this to determine whether
or not the channel supports HT40 or not. So to support HT40 you'll
need at a regulatory rule that allows you to use 40 MHz channels
but you're channel must also be enabled and support 20 MHz by itself.
The second pass is done after we do the regulatory checks over
an device's supported channel list. On each channel we'll check
if the control channel and the extension both:
o exist
o are enabled
o regulatory allows 40 MHz bandwidth on its frequency range
This work allows allows us to idependently check for HT40- and
HT40+.

Calling cancel_delayed_work() from inside
spin_lock_irqsave, introduces a potential deadlock.
As explained by Johannes Berg <johannes@sipsolutions.net>
A - lock
T - timer
phase CPU 1 CPU 2
---------------------------------------------
some place that calls
cancel_timer_sync()
(which is the | code)
lock-irq(A)
| "lock-irq"(T)
| "unlock"(T)
| wait(T)
unlock(A)
timer softirq
"lock"(T)
run(T)
"unlock"(T)
irq handler
lock(A)
unlock(A)
Now all that again, interleaved, leading to deadlock:
lock-irq(A)
"lock"(T)
run(T)
IRQ during or maybe
before run(T) --> lock(A)
"lock-irq"(T)
wait(T)
We fix this by moving the call to cancel_delayed_work() into workqueue.
There are cases where the work may not actually be queued or running
at the time we are trying to cancel it, but cancel_delayed_work() is
able to deal with this.
Also cleanup iwl_set_mode related to this call. This function
(iwl_set_mode) is only called when bringing interface up and there will
thus not be any scanning done. No need to try to cancel scanning.

One point of contention in high network loads is the dst_release() performed
when a transmited skb is freed. This is because NIC tx completion calls
dev_kree_skb() long after original call to dev_queue_xmit(skb).
CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is
quite visible if one CPU is 100% handling softirqs for a network device,
since dst_clone() is done by other cpus, involving cache line ping pongs.
It seems right place to release dst is in dev_hard_start_xmit(), for most
devices but ones that are virtual, and some exceptions.
David Miller suggested to define a new device flag, set in alloc_netdev_mq()
(so that most devices set it at init time), and carefuly unset in devices
which dont want a NULL skb->dst in their ndo_start_xmit().
List of devices that must clear this flag is :
- loopback device, because it calls netif_rx() and quoting Patrick :
"ip_route_input() doesn't accept loopback addresses, so loopback packets
already need to have a dst_entry attached."
- appletalk/ipddp.c : needs skb->dst in its xmit function
- And all devices that call again dev_queue_xmit() from their xmit function
(as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr

correctly if the cable is pulled. If all the members of a bonded device have
no carrier present, the bonded device itself needs to report no carrier present

If we can find a type NETDEV_HW_ADDR_T_SAN mac address from the
corresponding netdev for a fcoe interface then sets up added the
fc->ctlr.spma flag and stores spma mode address in ctl_src_addr.
In case the spma flag is set then:-
1. Adds spma mode MAC address in ctl_src_addr as secondary
MAC address, the FLOGI for FIP and pre-FIP will go out
using this address.
2. Cleans up stored spma MAC address in ctl_src_addr in
fcoe_netdev_cleanup.
3. Sets up spma bit in fip_flags for FIP solicitations along
with exiting FPMA bit setting.
4. Initialize the FLOGI FIP MAC descriptor to stored spma
MAC address in ctl_src_addr. This is used as proposed
FCoE MAC address from initiator along with both SPMA
and FPMA bit set in FIP solicitation, in response the
switch may grant any FPMA or SPMA mode MAC address to
initiator.
Removes FIP descriptor type checking against ELS type
ELS_FLOGI in fcoe_ctlr_encaps to update a FIP MAC descriptor,
instead now checks against FIP_DT_FLOGI.
I've tested this with available FPMA-only FCoE switch but
since data_src_addr is updated using same old code for
both FPMA and SPMA modes with FIP or pre-FIP links, so added
SPMA mode will work with SPMA-only switch also provided that
switch grants a valid MAC address.

Currently fcoe_netdev_config adds netdev pkt handler for fcoe pkts,
fcoe_if_create adds netdev pkt handler for fip packets, a secondary
MAC address is added by fcoe_netdev_config and then later cleanup
for these netdev related config/adds is done only during
fcoe_if_destroy and no cleanup done on error during fcoe interface
creation after above netdev config calling in fcoe_if_create.
So this patch adds single func for above mentioned cleanup the
fcoe_netdev_cleanup and then calls this func on either fcoe interface
destroy or exiting from fcoe_if_create due to an error after fcoe/fip
related above netdev config is done.
Moved netdev pkt handler addition code blocks for fip pkts close to
similar code block for foce pkt in fcoe_netdev_config, so that added
fcoe_netdev_cleanup could be called on error from fcoe_netdev_config
to undo these both additions for fcoe/fip pkt handlers. This move
required reference to fcoe_fip_recv in fcoe_netdev_config, so moved
fip related functions fcoe_fip_recv, fcoe_fip_send and
fcoe_update_src_mac above fcoe_netdev_config.
This consolidation will enable spma mode support in next patch to
easily add or delete spma mode mac address beside fixing current

After acquiring the SAN MAC address from the EEPROM, we need to program it
into one of the RARs. Also, DCB will use this MAC address to run DCBX
commands, so it doesn't have to play musical MAC addresses when things like
bonding enter the picture. So we need to return the MAC address through
the netlink interface to userspace.
This also moves the init_rx_addrs() call out of start_hw() and into
reset_hw(). We shouldn't try to read any of the RAR information before
initializing our internal accounting of the RAR table, which was what
was happening.

This patch implements the Storage Address entrypoint from the net device.
It will read the SAN MAC addresses from the EEPROM of the 82599 hardware,
and make them available to the FCoE stack through the net device.
Also, add/del the SAN MAC address to the netdev dev_addr_list via the
kernel api dev_addr_add()/dev_addr_del() when there is a valid SAN MAC
supported by the HW.

struct net_device trans_start field is a hot spot on SMP and high performance
devices, particularly multi queues ones, because every transmitter dirties
it. Is main use is tx watchdog and bonding alive checks.
But as most devices dont use NETIF_F_LLTX, we have to lock
a netdev_queue before calling their ndo_start_xmit(). So it makes
sense to move trans_start from net_device to netdev_queue. Its update
will occur on a already present (and in exclusive state) cache line, for
free.
We can do this transition smoothly. An old driver continue to
update dev->trans_start, while an updated one updates txq->trans_start.
Further patches could also put tx_bytes/tx_packets counters in
netdev_queue to avoid dirtying dev->stats (vlan device comes to mind)

When using bnx2 in a high transmit load, bnx2_tx_int() cost is pretty high.
There are two reasons.
One is an expensive call to bnx2_get_hw_tx_cons(bnapi) for each freed skb
One is cpu stalls when accessing skb_is_gso(skb) / skb_shinfo(skb)->nr_frags
because of two cache line misses.
(One to get skb->end/head to compute skb_shinfo(skb),
one to get is_gso/nr_frags)
This patch :
1) avoids calling bnx2_get_hw_tx_cons(bnapi) too many times.
2) makes bnx2_start_xmit() cache is_gso & nr_frags into sw_tx_bd descriptor.
This uses a litle bit more ram (256 longs per device on x86), but helps a lot.
3) uses a prefetch(&skb->end) to speedup dev_kfree_skb(), bringing
cache line that will be needed in skb_release_data()
result is 5 % bandwidth increase in benchmarks, involving UDP or TCP receive
& transmits, when a cpu is dedicated to ksoftirqd for bnx2.
bnx2_tx_int going from 3.33 % cpu to 0.5 % cpu in oprofile
Note : skb_dma_unmap() still very expensive but this is for another patch,
not related to bnx2 (2.9 % of cpu, while it does nothing on x86_32)

This patch provides new heuristics for parsing both the form factor and
media rotation rate ATA IDENFITY words.
The reported ATA version must be 7 or greater and the device must return
values defined as valid in the standard. Only then are the
characteristics reported to SCSI via the VPD B1 page.

is to move the intel fb sysrq over to V for video instead of G for

anywhere to be found in the mainline kernel, so the comments in the

This patch also cleans up the sysrq definitions for kgdb to make it

When the i2400m receives data and the device indicates there has to be
reordering, we keep an sliding window implementation to sort the
packets before sending them to the network stack.
One of the "operations" that the device indicates is "queue a packet
and update the window start". When the queue is empty, this is
equivalent to "deliver the packet and update the window start".
That case was optimized in i2400m_roq_queue_update_ws() so that we
would not pointlessly queue and dequeue a packet. However, when the
optimization was active, it wasn't updating the window start. That
caused the reorder management code to get confused later on with what
seemed to be wrong reorder requests from the device.
Thus the fix implemented is to do the right thing and update the
window start in both cases, when the queue is empty (and the
optimization is done) and when not.

This allows userlevel code to discover the pipe number corresponding
to a given CRTC ID. This is necessary for doing pipe-specific

There are a number of small form factor desktop systems with Intel mobile
graphics chips that lie and say they have an LVDS. With kernel mode-setting,
this becomes a problem, and makes native resolution boot go haywire -- for
example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to
have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080
display uses only the top left 1024x768, and auto-configured X will end
up only 1024x768 as well. With this change, graphical boot and X
both do 1920x1080 as expected.
Note that we're simply embracing and extending the early bail-out code
in place for the Mac Mini here. The xorg intel driver uses pci subsystem
device and vendor id for matching, while we're using dmi lookups here.

We might sleep here anyway so I hope an extra uncached read is ok to
add.
In #20896 we found that vbetool clobbers the IER. In KMS mode this is
particularly bad since we don't set the interrupt regs late (in
EnterVT), so we'd fail to get *any* interrupts at all after X started
(since some distros have scripts that call vbetool at X startup
apparently).
So this patch checks IER at wait_request time, and re-enables
interrupts if it's been clobbered. In a proper config this check
should never be triggered.
This is really a distro issue, but having a sanity check is nice, as
long as it doesn't have a real performance hit.

The older eeepc-acpi driver allowed to control the SHE performance
preset through a ACPI function for just this purpose. SHE underclocks
and undervolts the FSB and undervolts the CPU (at preset 2,
"powersave"), or slightly overclocks the CPU (at preset 0,
"performance"). Preset 1 is the default setting with default clocks and
voltage.

1) Buggy firmware can change the RFKILL state by itself. This is easily
detected. The RFKILL API states that in such cases, we should call
rfkill_force_state() to notify the core.
I have reported the bug to Asus. I believe this is the right thing
to do for robustness, even if this particular firmware bug is fixed.
2) The same bug causes the wireless toggle key to be reported as 0x11
instead of 0x10. 0x11 is otherwise unused, so it should be safe to
add this as a new keycode.
The bug is triggered by removing the laptop battery while hibernated.
On resume, the wireless toggle key causes the firmware to toggle the
wireless state itself. (Also, the key is reported as 0x11 when the
current wireless state is OFF).
This is very poor behaviour because the OS can't predict whether the
firmware is controlling the RFKILL state.
Without this workaround, the bug means users have to press the wireless
toggle key twice to enable, due to the OS/firmware conflict. (Assuming
rfkill-input or equivalent is being used). The workaround avoids this.
I believe that acpid scripts which toggle the value of the sysfs state file
when the toggle key is pressed will be rendered ineffective by the bug,
regardless of this workaround. If they simply toggle the state, when the
firmware has already toggled it, then you will never see a state change.

the sign of the change in brightness (if this is 0, no keypress is reported).

When an rfkill device is registered, the rfkill core will change its
state to the system default. So we need to prepare for state changes
*before* we register it. That means installing the eeepc-specific ACPI
callback which handles the hotplug of the wireless network adaptor.
This problem doesn't occur during normal operation. You have to
1) Boot with wireless enabled. eeepc-laptop should load automatically.
2) modprobe -r eeepc-laptop
3) modprobe eeepc-laptop
On boot, the default rfkill state will be set to enabled.
With the current core code, step 2) will disable the wireless.
Therefore in step 3), the wireless will change state during registration,
from disabled to enabled. But without this fix, the PCI device for the
wireless adaptor will not appear.

Also, pass _all_ policy wrt. enabling PS to mac80211, since
we do not use the power_disabled internally I now use that to
mirror the mac80211 CONF_PS setting. When mac80211 turns off
CONF_PS we follow suit. This means that the user power level
(which can currently only be set from sysfs) is not touched
for mac80211 powersave changes.
This means no "association status" checks are necessary since

iwlwifi internally needs to keep track of whether PS
is enabled in the firmware or not. To do this, it keeps
a bit in the status flags, called STATUS_POWER_PMI.
The code to set this bit looks as follows:
static int iwl_set_power(struct iwl_priv *priv, void *cmd)
{
return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD,
sizeof(struct iwl_powertable_cmd),
cmd, NULL);
}
int iwl_power_update_mode(...)
{
[...]
if (final_mode != IWL_POWER_MODE_CAM)
set_bit(STATUS_POWER_PMI, &priv->status);
iwl_update_power_cmd(priv, &cmd, final_mode);
cmd.keep_alive_beacons = 0;
if (final_mode == IWL_POWER_INDEX_5)
cmd.flags |= IWL_POWER_FAST_PD;
ret = iwl_set_power(priv, &cmd);
if (final_mode == IWL_POWER_MODE_CAM)
clear_bit(STATUS_POWER_PMI, &priv->status);
else
set_bit(STATUS_POWER_PMI, &priv->status);
if (priv->cfg->ops->lib->update_chain_flags && update_chains)
priv->cfg->ops->lib->update_chain_flags(priv);
[...]
}
Now, this bit really needs to track what the _firmware_
thinks, not what the driver thinks. Therefore, there is
a race condition here -- the driver sets the bit before
it knows that the async command sent to the card in the
iwl_set_power function has been processed. As a result,
the call to update_chain_flags() may think that the card
has been woken up (PMI bit cleared) while in reality it
hasn't processed the async POWER_TABLE_CMD yet.
This leads to bugs -- any commands the update_chain_flags
function sends can get stuck and subsequent commands also
fail.
The fix is almost trivial: since there's no reason to send
an async command here (in fact, there almost never should
be since many mac80211 callbacks can sleep) just make the
function wait for the card to process the command and then
return and clear the PMI bit.

Error timestamps are in jiffies which doesn't run while suspended and
PHY events during resume isn't too uncommon. When the two are
combined, it can lead to unnecessary speed downs if the machine is
suspended and resumed repeatedly. Clear error history on resume.

The original driver doesn't use 66 MHz clock for UDMA33.
[ The alternative solution would be to adjust UDMA33 timings
for 66 MHz clock but I think that it is safer to stick with
old & tested behavior for now. ]

New device attach path in ata_eh_revalidate_and_attach() is divided
into two separate loops because ATA requires IDENTIFY to be issued to
slave first while the user expects to see device probe messages from
the master device. new_mask is used to track which devices are the
new ones between the first loop and the second.
This usually works well but if an error occurs during configuration
stage, ata_dev_revalidate_and_attach() returns with error code and
forgets new_mask. On the retry run, dev->class is set and new_mask
for the device is clear, so the device just gets revalidated and thus
ends up skipping post-configuration procedure including scheduling of
SCSI_HOTPLUG for the device. When this occurs, ATA part of probing
works fine but SCSI probing usually doesn't happen and makes the
device unreachable.
The behavior has been around for a very long time but it has been
uncovered with the recent addition of 1_5_GBPS horkage which uses
-EAGAIN return value from ata_dev_configure() to restart the probing
sequence after forcing cable speed.
This can be fixed by making sure dev->class is permanently set only
after all configurations are successfully complete. Fix it.

This patch (as1240) adds the NOGET quirk for three devices from CH
Products: the Pro pedals, the Combatstick joystick, and the Flight-Sim
yoke. Without these quirks, the devices haven't worked for many
kernel releases. Sometimes replugging them after boot-up would get
them to work and sometimes they wouldn't work at all.

PAGE_MASK is 0xFFFFF000 on i386 -- even with PAE.
So it's not sufficient to ensure that you use phys_addr_t or uint64_t
everywhere you handle physical addresses -- you also have to avoid using
the construct 'addr & PAGE_MASK', because that will strip the high 32
bits of the address.
This patch avoids that problem by using PHYSICAL_PAGE_MASK instead of
PAGE_MASK where appropriate. It leaves '& PAGE_MASK' in a few instances
that don't matter -- where it's being used on the virtual bus addresses
we're dishing out, which are 32-bit anyway.
Since PHYSICAL_PAGE_MASK is not present on other architectures, we have
to define it (to PAGE_MASK) if it's not already defined.
Maybe it would be better just to fix PAGE_MASK for i386/PAE?

This patch adds three attribute files in /sys/class/net/$dev/ for tun
devices; allowing userspace to obtain the information which TUNGETIFF
offers, and more, but without having to attach to the device in question
(which may not be possible if it's in use).
It also fixes a bug which has been present in the TUNGETIFF ioctl since
its inception, where it would never set IFF_TUN or IFF_TAP according to
the device type. (Look carefully at the code which I remove from
tun_get_iff() and how the new tun_flags() helper is subtly different).
