6e583ce524 net: eliminate refcounting in backlog queue
Avoid the overhead of atomic increment/decrement on each received packet.
This helps performance of non-NAPI devices (like loopback).
Use cleanup function to walk queue on each cpu and clean out any
left over packets.

283d07ac20 ipv6: Do not drop packet if skb->local_df is set to true
The old code will drop IPv6 packet if ipfragok is not set, since
ipfragok is obsoleted, will be instead by used skb->local_df, so this
check must be changed to skb->local_df.

This patch fix this problem and not drop packet if skb->local_df is
set to true.

f880374c2f sctp: Drop ipfargok in sctp_xmit function
The ipfragok flag controls whether the packet may be fragmented
either on the local host on beyond.  The latter is only valid on
IPv4.

In fact, we never want to do the latter even on IPv4 when PMTU is
enabled.  This is because even though we can't fragment packets
within SCTP due to the prtocol's inherent faults, we can still
fragment it at IP layer.  By setting the DF bit we will improve
the PMTU process.

RFC 2960 only says that we SHOULD clear the DF bit in this case,
so we're compliant even if we set the DF bit.  In fact RFC 4960
no longer has this statement.

Once we make this change, we only need to control the local
fragmentation.  There is already a bit in the skb which controls
that, local_df.  So this patch sets that instead of using the
ipfragok argument.

The only complication is that there isn't a struct sock object
per transport, so for IPv4 we have to resort to changing the
pmtudisc field for every packet.  This should be safe though
as the protocol is single-threaded.

Note that after this patch we can remove ipfragok from the rest
of the stack too.

e5a4a72d4f net: use software GSO for SG+CSUM capable netdevices
If a netdevice does not support hardware GSO, allowing the stack to
use GSO anyway and then splitting the GSO skb into MSS-sized pieces
as it is handed to the netdevice for transmitting is likely still
a win as far as throughput and/or CPU usage are concerned, since it
reduces the number of trips through the output path.

This patch enables the use of GSO on any netdevice that supports SG.
If a GSO skb is then sent to a netdevice that supports SG but does not
support hardware GSO, net/core/dev.c:dev_hard_start_xmit() will take
care of doing the necessary GSO segmentation in software.

745e203164 net: fix missing pneigh entries in the neighbor seq_file code
When pneigh entries exist, but the user's read buffer isn't sufficient to
hold them all, one of the pneigh entries will be missing from the results.

In neigh_get_idx_any, the number of elements which neigh_get_idx
encountered is not correctly subtracted from the position number before
the call to pneigh_get_idx.  neigh_get_idx reduces the position by 1 for
each call to neigh_get_next, but it does not reduce it by one for the
first element (neigh_get_first). The patch alters the neigh_get_idx and
pneigh_get_idx functions to subtract one from pos, for the first element,
when pos is non-zero.

3ab36ab685 try harder to load tty ldisc driver
Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.

Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.

I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.

Some platform decide whether they support huge pages at boot time.  On

The patches to introduce multiple huge pages support broke that causing

support for multiple page sizes.

c6de002617 Missing symbol prefix on vmlinux.lds.h
ARCH=h8300:

init/main.c:781: undefined reference to `___early_initcall_end'

Same problem have
__start___bug_table
__stop___bug_table
__tracedata_start
__tracedata_end
__per_cpu_start
__per_cpu_end

When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL adds a prefix charactor.

You can't just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions.  in the
case of Blackfin/h8300, the ABI dictates that any C-visible symbols have
an underscore prefixed to them.  Thus all symbols in vmlinux.lds.h need to
be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic
in their own files.

ea44c1d60d PNP: fix formatting of dbg_pnp_show_resources() output
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.

Also, use scnprintf() rather than snprintf() when building up the
buffer to print.  scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).

snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer.  That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.

Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:
    http://marc.info/?l=linux-kernel&m=121736480005656&w=2

Some users of the RTL8187B have experienced difficulties since commit
49292d5635 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.

The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>,
who also suggested this type of fix.

ada662f3eb rt2x00: Fix partial antenna configuration
The if-statement to determine the new TX/RX antenna
configuration was incomplete. It lacks the general
else-clause when the antenna wasn't changed.

This is a correct event, since it can occur when only
one of the antenna's has been changed or when the new
configuration is being forced (like when the interface
has just been added).

d2b690714c rt2x00: Fix access permissions on debugfs files
Although most rt2x00 debugfs files don't contain
information which could compromise network security,
it is better to set the access permissions to root only.

This will be required when HW crypto is implemented,
because it could be possible to read the HW key from
the registers.

143b09efb7 iwlwifi: don't stop queue in the middle of fragmented packet
This patch avoids stopping queue in the middle of the fragmented packet.
It is required that there will be ~10 (max packet/min fragment) or 16
(4 bits of frag number) free tfds all the time.

6e28fbef0f rfkill: query EV_SW states when rfkill-input (re)?connects to a input device
Every time a new input device that is capable of one of the
rfkill EV_SW events (currently only SW_RFKILL_ALL) is connected to
rfkill-input, we must check the states of the input EV_SW switches
and take action.  Otherwise, we will ignore the initial switch state.

We also need to re-check the states of the EV_SW switches after
a device that was under an exclusive grab is released back to us,
since we got no input events from that device while it was grabbed.
