1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI.
2. The MISDN config option appeared between ISDN_I4L and the I4L hardware
driver options; move it to a less irritating place.
3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so
move it from the I4L section to the general section.
4. ISDN_HDLC is now also used by drivers outside I4L. Move it from the
I4L section to the general section, too.Signed-off-by: Tilman Schmidt

Do a PHY reset to test if there is an active phy and set the PHY address
to B44_PHY_ADDR_NO_PHY in case of an not active phy. This is needed for

The PowerPC architecture does not require loads to independent bytes to be
ordered without adding an explicit barrier.In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.The problem occurs with packet split enabled where the TCP/IP header and data
are in different descriptors. If the reads go out of order we may have data
that doesn't match the TCP/IP header. Since we use hardware checksumming this
bad data is never verified and it makes it all the way to the application.This bug was found during stress testing and adding this barrier has been shown
to fix it.Signed-off-by: Milton Miller

Currently use of 64-bit DMA is disabled in r8169 unless the user passes the
use_dac module option. This is reasonable for conventional PCI devices where
broken chipsets may not handle dual-address-cycle transfers properly for
32-bit slots and so this may not be safe. However, PCI Express should not have
this problem and not using 64-bit DMA results in DMA transfers needlessly using
the IOMMU or SWIOTLB. Set the use_dac module parameter to a new default value of
-1 which results in 64-bit DMA being enabled by default for PCI Express devices
only.Signed-off-by: Robert Hancock

There are only two users of the dma_sync_single_range_for_cpu/device
API in mainline (mlx4 and ssb). The
dma_sync_single_range_for_cpu/device API has never been documented and
the dma_sync_single_for_cpu/device API also support a partial sync.This converts mlx4 to use the dma_sync_single_for_cpu/device API
(preparations for the removal of the dma_sync_single_range_for_cpu/device API).Signed-off-by: FUJITA Tomonori

To see the effect make sure you have an empty SPD.
On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush"
You get prompt back in window2 and you see the flush event on window1.
With this fix, you still get prompt on window1 but no event on window2.Thanks to Alexey Dobriyan for finding a bug in earlier version
when using pfkey to do the flushing.Signed-off-by: Jamal Hadi Salim

RFC 2367 says flushing behavior should be:
1) user space -> kernel: flush
2) kernel: flush
3) kernel -> user space: flush event to ALL listenersThis is not realistic today in the presence of selinux policies
which may reject the flush etc. So we make the sequence become:
1) user space -> kernel: flush
2) kernel: flush
3) kernel -> user space: flush response to originater from #1
4) if there were no errors then:
kernel -> user space: flush event to ALL listenersSigned-off-by: Jamal Hadi Salim

This patch fixes a bug that triggers an assertion if you create
a conntrack entry with a helper and netfilter debugging is enabled.
Basically, we hit the assertion because the confirmation flag is
set before the conntrack extensions are added. To fix this, we
move the extension addition before the aforementioned flag is
set.This patch also removes the possibility of setting a helper for
existing conntracks. This operation would also trigger the
assertion since we are not allowed to add new extensions for
existing conntracks. We know noone that could benefit from
this operation sanely.Thanks to Eric Dumazet for initial posting a preliminary patch
to address this issue.Reported-by: David Ramblewski

Due to lack of time, space, motivation, hardware and probably expertise,
I have reluctantly decided to orphan the DECnet code in the kernel.Judging by the deafening silence on the linux-decnet mailing list I
suspect it's either not being used anyway, or the few people that are
using it are happy with their older kernels.Signed-Off-By: Christine Caulfield

This patch enables fast retransmissions after one dupACK for
TCP if the stream is identified as thin. This will reduce
latencies for thin streams that are not able to trigger fast
retransmissions due to high packet interarrival time. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin.Signed-off-by: Andreas Petlund

This patch will make TCP use only linear timeouts if the
stream is thin. This will help to avoid the very high latencies
that thin stream suffer because of exponential backoff. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin. A maximum of 6 linear
timeouts is tried before exponential backoff is resumed.Signed-off-by: Andreas Petlund
