NFLOG timeout was computed in timer by doing:

    flushtimeout*HZ/100

Default value of flushtimeout was HZ (for 1 second delay). This was
wrong for non 100HZ computer. This patch modify the default delay by
using 100 instead of HZ.

In NFLOG the per-rule qthreshold should overrides per-instance only
it is set. With current code, the per-rule qthreshold is 1 if not set
and it overrides the per-instance qthreshold.

This patch modifies the default xt_NFLOG threshold from 1 to
0. Thus a value of 0 means there is no per-rule setting and the instance
parameter has to apply.

A long time ago we had bugs, primarily in TCP, where we would modify
skb->truesize (for TSO queue collapsing) in ways which would corrupt
the socket memory accounting.

skb_truesize_check() was added in order to try and catch this error
more systematically.

However this debugging check has morphed into a Frankenstein of sorts
and these days it does nothing other than catch false-positives.

If a USB PCI controller is behind a cardbus bridge, we are trying to
restore its configuration registers too early, before the cardbus
bridge is operational.  To fix this, call pci_restore_state() from
usb_hcd_pci_resume() and remove usb_hcd_pci_resume_early() which is
no longer necessary (the configuration spaces of USB controllers that
are not behind cardbus bridges will be restored by the PCI PM core
with interrupts disabled anyway).

This patch fixes the regression from 2.6.28 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12659

[ Side note: the proper long-term fix is probably to just force the
  unplug event at suspend time instead of doing a plug/unplug at resume
  time, but this patch is fine regardless  - Linus ]

This is the cause of the DMA faults and disk corruption that people have
been seeing. Some chipsets neglect to report the RWBF "capability" --
the flag which says that we need to flush the chipset write-buffer when
changing the DMA page tables, to ensure that the change is visible to
the IOMMU.

Override that bit on the affected chipsets, and everything is happy
again.

Getting this wrong caused

	WARNING: at fs/namespace.c:636 mntput_no_expire+0xac/0xf2()

due to optimistically checking cpu_writer->mnt outside the spinlock.

Here's what we really want:
 * we know that nobody will set cpu_writer->mnt to mnt from now on
 * all changes to that sucker are done under cpu_writer->lock
 * we want the laziest equivalent of
	spin_lock(&cpu_writer->lock);
	if (likely(cpu_writer->mnt != mnt)) {
		spin_unlock(&cpu_writer->lock);
		continue;
	}
	/* do stuff */
  that would make sure we won't miss earlier setting of ->mnt done by
  another CPU.

Anyway, for now we just move the spin_lock() earlier and move the test
into the properly locked region.

If the F71882FG chip is at address 0x4e, then the probe at 0x2e will

This is misleading because there is a Fintek device, just at a

The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug
causing decoder commands to crash. The decoder commands should have been
handled from the video_ioctl2 default handler, ensuring correct mapping
of the argument between user and kernel space. Unfortunately they ended
up before the video_ioctl2 call, causing random crashes.

cause!

If a device using the gspca framework is unplugged while it is still streaming
then the call that is used to free the URBs that have been allocated occurs
after the pointer it uses becomes invalid at the end of gspca_disconnect.
Make another cleanup call in gspca_disconnect while the pointer is still
valid (multiple calls are OK as destroy_urbs checks for pointers already

This change set is wrong. The affected functions cannot be called from
an interrupt context, because they may process large buffers. In this
case, interrupts are disabled for a long time. Functions, like
dvb_dmx_swfilter_packets(), could be called only from a tasklet.

This change set does hide some strong design bugs in dm1105.c and
au0828-dvb.c.

Please revert this change set and do fix the bugs in dm1105.c and
au0828-dvb.c (and other files).

This changeset _must_ be reverted! It breaks all kernels since 2.6.27
for applications which use DVB and require a low interrupt latency.

It is a very bad idea to call the demuxer to process data buffers with
interrupts disabled!

I agree, this is bad.  The demuxer is far too much work to be done with
IRQs off.  IMHO, even doing it under a spin-lock is excessive.  It should
be a mutex.  Drivers should use a work-queue to feed the demuxer.

Thank you for testing this changeset and discovering the issues on it.
