Previously, it was only being set if passed GDRST_FULL - but the only
caller passed GDRST_RENDER.  So the hardware never actually reset.
The comments also did not match the code.

Instead, just set the reset bit regardless of what flags were passed.
The GPU now resets correctly on my GM45.

"param->u.wpa_associate.wpa_ie_len" comes from the user.  We should
check it so that the copy_from_user() doesn't overflow the buffer.

Also further down in the function, we assume that if
"param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is
initialized.  To make that work, I changed the test here to say that if
"wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return
-EINVAL.

Oddly, we only use the first element of the abyWPAIE[] array.  So I
suspect there may be some other issues in this function.

This reverts commit 96d592ed.

The netfilter hook seems to be misused and may leak skbs in situations
when NF_HOOK returns NF_STOLEN. It may not filter everything as
expected. Also the ethernet bridge tables are not yet capable to
understand batman-adv packet correctly.

It was only added for testing purposes and can be removed again.

Commit 461c3177(into 2.6.36-v3)
is put forward to power down phy if no usb cable is connected,
but does introduce the two issues below:

1), phy is not into work state if usb cable is connected
with PC during poweron, so musb device mode is not usable
in such case, follows the reasons:
	-twl4030_phy_resume is not called, so
		regulators are not enabled
		i2c access are not enabled
		usb mode not configurated

2), The kernel warings[1] of regulators 'unbalanced disables'
is caused if poweron without usb cable connected
with PC or b-device.

This patch fixes the two issues above:
	-power down phy only if no usb cable is connected with PC
and b-device
	-do phy initialization(via __twl4030_phy_resume) if usb cable
is connected with PC(vbus event) or another b-device(ID event) in
twl4030_usb_probe.

This patch also doesn't put VUSB3V1 LDO into active mode in
twl4030_usb_ldo_init until VBUS/ID change detected, so we can
save more power consumption than before.

This patch is verified OK on Beagle board either connected with
usb cable or not when poweron.

During heavy aperture thrashing we may be forced to wait upon several active
objects during eviction. The active list may be the last reference to
these objects and so the action of waiting upon one of them may cause
another to be freed (and itself unbound). To prevent the object
disappearing underneath us, we need to acquire and hold a reference
whilst unbinding.

This should fix the reported page refcount OOPS:

Use the GMBUS interface rather than direct bit banging to grab the EDID
over DDC (and for other forms of auxiliary communication with external
display controllers). The hope is that this method will be much faster
and more reliable than bit banging for fetching EDIDs from buggy monitors
or through switches, though we still preserve the bit banging as a
fallback in case GMBUS fails.

These are not fatal errors, so do not alarm the user by filling the
logs with *** ERROR ***. Especially as we know that g4x CRT detection
is a little sticky.

On the one hand the errors are valid since they are warning us of a
stall -- we poll the register whilst holding the mode lock so not even
the mouse will update. On the other hand, those stalls were already present
yet nobody complained.

If an array with 1.x metadata is assembled with the last disk missing,
md doesn't properly record the fact that the disk was missing.

This is unlikely to cause a real problem as the event count will be
different to the count on the missing disk so it won't be included in
the array.  However it could still cause confusion.

So make sure we clear all the relevant slots, not just the early ones.

Now that we depend on md_update_sb to clear variable bits in
mddev->flags (rather than trying not to set them) it is important to
always call md_update_sb when appropriate.

md_check_recovery has this job but explicitly avoids it for ->external
metadata arrays.  This is not longer appropraite, or needed.

However we do want to avoid taking the mddev lock if only
MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for
external-metadata arrays.

if that option is off.

The stand-alone driver drivers/ieee1394/init_ohci1394_dma*  will soon be
moved into drivers/firewire/ too and will require the same makefile fix.

Side effect:
As mentioned in https://bugzilla.novell.com/show_bug.cgi?id=586172#c24
this influences the order in which either firewire-ohci or ohci1394 is
going to be bound to an OHCI-1394 controller in case of a modular build
of both drivers if no modprobe blacklist entries are configured.
However, a user of such a setup cannot expect deterministic behavior
anyway.  The Kconfig help and the migration guide at
ieee1394.wiki.kernel.org recommend blacklist entries when a dual
IEEE 1394 stack build is being used.  (The coexistence period of the two
stacks is planned to end soon.)

The Thinkpad X100e seems to have some odd behaviour when the display is
powered off - the onboard r8169 starts generating rxfifo overflow errors.
The root cause of this has not yet been identified and may well be a
hardware design bug on the platform, but r8169 should be more resiliant to
this. This patch enables the rxfifo interrupt on 8168 devices and removes
the MAC version check in the interrupt handler, and the machine no longer
crashes when under network load while the screen turns off.

The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246
bytes of uninitialized stack memory, because the "reserved" member of
the viafb_ioctl_info struct declared on the stack is not altered or
zeroed before being copied back to the user.  This patch takes care of
it.

vortex_set_wol protected with a spinlock, but nested  acpi_set_WOL acquires a mutex inside atomic context.
Ethtool operations are already serialized by RTNL mutex, so it is safe to drop the locks.

Since it may be already enabled by bootloader or some other utility. This patch
makes sure that the watchdog is disabled before any userspace daemon opens the
device. It is also required by the watchdog API.

Some pcnet_cs compatible cards require an exact 16-lines match
of the ioport areas specified in CIS, but set the "iolines"
value in the CIS incorrectly. We can easily work around this
issue -- same as we do in serial_cs -- by first trying setting
iolines to the CIS-specified value, and then trying a 16-line
match.

As the iomem / ioport setup differs per device, it is much better
to print out the device instead of the socket.

We shouldn't overwrite pre-set values, and we should also
set the port address to the beginning, and not the end of
the 8-port range.
