e76678dd65 ixgbe: set max desc to prevent total RSC packet size of 64K
The performance of hardware RSC is greatly reduced if the total for max rsc
descriptors multiplied by the buffer size is greater than 65535.  To
prevent this we need to adjust the max rsc descriptors appropriately.

eb0519b5a1 mv643xx_eth: fix PPC DMA breakage
After 2.6.29, PPC no more admits passing NULL to the dev parameter of
the DMA API. The result is a BUG followed by solid lock-up when the 
mv643xx_eth driver brings an interface up. The following patch makes 
the driver work on my Pegasos again; it is mostly a search and replace 
of NULL by mp->dev->dev.parent in dma allocation/freeing/mapping/unmapping
functions.

4cd6fe1c64 bonding: fix link down handling in 802.3ad mode
One of the purposes of bonding is to allow for redundant links, and failover
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
to user space so management tools (like routing daemons) can respond.

Bonding in 802.3ad mode does not work correctly for this because it incorrectly
chooses a link that is down as a possible aggregator.

When running in DCB mode, switching between link flow control and priority
flow control shouldn't need to reset the hardware.  This removes that
reset.

This also extends the set_all() dcbnl callback to return a value indicating

264857b8fe ixgbe: Allow link flow control in DCB mode for 82599 adapters
82599 supports using either link flow control or priority flow control when
in DCB mode.  The dcbnl interface already supports sending down
configurations through rtnetlink that can enable LFC when DCB is enabled,
so the driver should take advantage of this.

82598 does not support using LFC when DCB is enabled, so explicitly disable
it when we're in DCB mode.  This means we always run in PFC mode when DCB
is enabled.

184dd3459b fcoe: adds spma mode support
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.

ab6b85c1d7 fcoe: consolidates netdev related config and cleanup for spma mode
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
no cleanup issue during error.

aca6bee75f ixgbe: Add SAN MAC address to the RAR, return the address to DCB
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.

9d21493b4b net: tx scalability works : trans_start
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)

d62fda082c bnx2: bnx2_tx_int() optimizations
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)

a0bf284bfe ACPI: Idle C-states disabled by max_cstate should not disable the TSC
Processor idle power states C2 and C3 stop the TSC on many machines.
Linux recognizes this situation and marks the TSC as unstable:

Marking TSC unstable due to TSC halts in idle

But if those same machines are booted with "processor.max_cstate=1",
then there is no need to validate C2 and C3, and no need to
disable the TSC, which can be reliably used as a clocksource.

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.

This seems like a reasonable compromise to me considering that we have
been shipping several kernel releases that key off the rotation rate bit
without any version checking whatsoever.  With no complaints so far.

364b5b7b1d sysrq, intel_fb: fix sysrq g collision
Commit 79e539453b introduced a
regression where you cannot use sysrq 'g' to enter kgdb.  The solution
is to move the intel fb sysrq over to V for video instead of G for
graphics.  The SMP VOYAGER code to register for the sysrq-v is not
anywhere to be found in the mainline kernel, so the comments in the
code were cleaned up as well.

This patch also cleans up the sysrq definitions for kgdb to make it
generic for the kernel debugger, such that the sysrq 'g' can be used
in the future to enter a gdbstub or another kernel debugger.

4e5b6d006b wimax/i2400m: fix device crash: fix optimization in _roq_queue_update_ws
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.

425d244c86 drm/i915: ignore LVDS on intel graphics systems that lie about having it
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.
The MSI addition is courtesy of and tested by Bill Nottingham.

802c7eb646 drm/i915: sanity check IER at wait_request time
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.

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.

Tested on "EEEPC 4G" only.

64b86b6583 eeepc-laptop: report brightness control events via the input layer
This maps the brightness control events to one of two keys, either
KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed.

Some mapping has to be done due to the fact that the BIOS reports them as
<base value> + <current brightness index>; the selection is done according to
the sign of the change in brightness (if this is 0, no keypress is reported).

fbc97e4c5c eeepc-laptop: fix wlan rfkill state change during init
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.

[map
ped as single] [unmapped as page]

The ioatdma driver was unmapping all regions
(either allocated as page or single) using unmap_page.
This patch lets dma driver recognize if unmap_single or unmap_page should be used.
It introduces two new dma control flags:
DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE.
They should be set to indicate dma driver to do dma-unmapping as single
(first one for the source, tha latter for the destination).
If respective flag is not set, the driver assumes dma-unmapping as page.

7af2c46078 iwlwifi: clean up PS code
This removes all the dead code that tries to adjust the power
saving level based on the system AC state (inacceptable policy
in the kernel) or based on overtemp conditions (unused).

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
mac80211 will not allow power save to be enabled when not
associated.

f0f74a0e65 iwlwifi: fix PS disable status race
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.

209d889bab ath5k: update channel in sw state after stopping RX and TX
This fixes a non-theoretical race condition when transmitting and
receiving frames during a scan.  If the channel or operating band
changes while processing status descriptors in the tasklets, ath5k
will incorrectly use the new channel and band when reporting the
rates, even if the frame was actually sent on a previous channel.

Typically this will manifest as a beacon found on an incorrect
frequency and/or a warning in the driver while scanning:

842faa6c1a libata: fix attach error handling
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.

fd18de50b9 intel-iommu: PAE memory corruption fix
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?

980c9e8cee tun: add tun_flags, owner, group attributes in sysfs
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).

7564f67d5b V4L/DVB (11669): uvc: fix compile warning
The 2.6.30 kernel generates this warning:

uvc_driver.c:1729: warning: 'ret' may be used uninitialized in this function

I guess some new warning flag must have been turned on since this warning
didn't appear with older kernels (gcc version 4.3.1). It's also a bogus
warning, but since this code didn't comply to the coding standard anyway
I've modified it to 1) remove the warning and 2) conform to the coding
standard.

7ecc0cf937 V4L/DVB (11662): v4l2-ioctl: Clear buffer type specific trailing fields/padding
Some ioctls have structs that are a different size depending on what type
of buffer is being used.  If the buffer type leaves a field unused or has
padding space at the end, this space should be zeroed out.

The problems with S_FMT and REQBUFS were original identified and patched by
Marton Nemeth <nm127@freemail.hu>.

1175d6131f V4L/DVB (11661): v4l2-ioctl: Check buffer types using g_fmt instead of try_fmt
For a number of different ioctls, the v4l2-ioctl code checks that the
passed buffer type is supported by the driver.  It did this by checking
that the driver defined a method for the try_fmt handler for that buffer
type.  However, try_fmt is optional and a driver might not provide it even
though it does support that type.  So use g_fmt instead, since that isn't
optional.

This should fix a problem with VBI capture with saa7146.

If someone requests a format at fmt->index == (unsigned)-1 and the first

-1 when it's compared to fmt->index and there will appear to be a match.

Restructure the loop so this can't happen.  It's simpler this way too.  The

both are also called/scheduled via bond_free_all().

bond_destroy_sysfs is unecessary because the sysfs entry has

e67c85626c Revert driver core: move platform_data into platform_device
This reverts commit 006f4571a1:

	This patch moves platform_data from struct device into
	struct platform_device, based on the two ideas:

	1. Now all platform_driver is registered by platform_driver_register,
	   which makes probe()/release()/... of platform_driver passed parameter
	   of platform_device *, so platform driver can get platform_data from
	   platform_device;

	2. Other kind of devices do not need to use platform_data, we can
	   decrease size of device if moving it to platform_device.

	Taking into consideration of thousands of files to be fixed and they
	can't be finished in one night(maybe it will take a long time), so we
	keep platform_data in device to allow two kind of cases coexist until
	all platform devices pass its platfrom data from
	platform_device->platform_data.

	All patches to do this kind of conversion are welcome.

As we don't really want to do it, it was a bad idea.

	To make the conversion easily, we allow platform specific data
	passed by struct device or struct platform_device and platform
	driver may use it from struct device or struct platform_device.

As we really don't want to do this at all.
