444ce9d44d MAINTAINERS: Add separate section for USB NETWORKING DRIVERS
There are several drivers in drivers/net/usb/ that
do not have specific MAINTAINERS that should have
emails forwarded to the linux-usb mailing list.

Add a section for those drivers.

b706535441 xhci: Misc bug fixes for 3.11.
Hi Greg,
 
 Here's two small fixes for 3.11.  The first patch fixes a 5 second hang in
 khubd after a USB device disconnect on some xHCI hosts.  The second fixes a
 build warning.

bf37d2b3fd busy_poll: cleanup do-nothing placeholders
When renaming ll_poll to busy poll, I introduced a typo
in the name of the do-nothing placeholder for sk_busy_loop
and called it sk_busy_poll.
This broke compile when busy poll was not configured.
Cong Wang submitted a patch to fixed that.
This patch removes the now redundant, misspelled placeholder.

b3b301c5fe ACPI / video: improve quirk check in acpi_video_bqc_quirk()
If the _BCL package ordering is descending, the first level
(br->levels[2]) is likely to be 0, and if the number of levels
matches the number of steps, we might confuse a returned level to
mean the index.

For example:

  current_level = max_level = 100
  test_level = 0
  returned level = 100

In this case 100 means the level, not the index, and _BCM failed.
Still, if the _BCL package ordering is descending, the index of
level 0 is also 100, so we assume _BQC is indexed, when it's not.

This causes all _BQC calls to return bogus values causing weird
behavior from the user's perspective.  For example:

xbacklight -set 10; xbacklight -set 20;

would flash to 90% and then slowly down to the desired level (20).

The solution is simple; test anything other than the first level
(e.g. 1).

d6f67eb787 ARM: STi: remove sti_secondary_start from INIT section.
This patch removes sti_secondary_start from _INIT section, there are 2
reason for this removal.
 1. discarding such a small code does not save much, given the RAM
sizes.
 2. Having this code discarded, creates corruption issue when we boot
smp-kernel with nrcpus=1 or with single cpu node in DT.

bbbeaef371 Fixes for omap5-uevm regulators from Nishanth Menon <nm@ti.com>:
Due to wrong older revision of documentation used as reference, we
 seem to have a bunch of LDOs wrongly configured on OMAP5 uEVM. This
 series is based power tree on production board 750-2628-XXX platform.
 Unfortunately, the wrong voltages may be detrimental to OMAP5 as they
 supply hardware blocks at voltages that are out of specification.
 
 There is a chance that without these fixes there can be hardware
 damage to omap5-uevm boards with the v3.11-rc series.

f27070158d ax88179_178a: avoid copy of tx tcp packets
ax88179_tx_fixup() has quite complex code trying to push 8 bytes
of control data (len/mss), but fails to do it properly for TCP packets,
incurring an extra copy and point of memory allocation failure.

Lets use the simple and approved way.

dev->needed_headroom being 8, all frames should have 8 bytes of
headroom, so the extra copy should be unlikely anyway.

This patch should improve performance for TCP xmits.

73f5698e77 fib_rules: fix suppressor names and default values
This change brings the suppressor attribute names into line; it also changes
the data types to provide a more consistent interface.

While -1 indicates that the suppressor is not enabled, values >= 0 for
suppress_prefixlen or suppress_ifgroup  reject routing decisions violating the
constraint.

This changes the previously presented behaviour of suppress_prefixlen, where a
prefix length _less_ than the attribute value was rejected. After this change,
a prefix length less than *or* equal to the value is considered a violation of
the rule constraint.

It also changes the default values for default and newly added rules (disabling
any suppression for those).

This doesn't show up unless you do quite a bit of testing; a simple
boot test does not do this, so all my nightly tests were passing fine.

The reason for this is that install_special_mapping() expects the

which was stored on the kernel stack, that's why this was blowing up.

9457158bbc tracing: Fix reset of time stamps during trace_clock changes
Fixed two issues with changing the timestamp clock with trace_clock:

 - The global buffer was reset on instance clock changes. Change this to pass
   the correct per-instance buffer
 - ftrace_now() is used to set buf->time_start in tracing_reset_online_cpus().
   This was incorrect because ftrace_now() used the global buffer's clock to
   return the current time. Change this to use buffer_ftrace_now() which
   returns the current time for the correct per-instance buffer.

Also removed tracing_reset_current() because it is not used anywhere

ed5467da0e tracing: Fix fields of struct trace_iterator that are zeroed by mistake
tracing_read_pipe zeros all fields bellow "seq". The declaration contains
a comment about that, but it doesn't help.

The first field is "snapshot", it's true when current open file is
snapshot. Looks obvious, that it should not be zeroed.

The second field is "started". It was converted from cpumask_t to
cpumask_var_t (v2.6.28-4983-g4462344), in other words it was
converted from cpumask to pointer on cpumask.

Currently the reference on "started" memory is lost after the first read
from tracing_read_pipe and a proper object will never be freed.

The "started" is never dereferenced for trace_pipe, because trace_pipe
can't have the TRACE_FILE_ANNOTATE options.

6a8b7f0c85 netlabel: use domain based selectors when address based selectors are not available
NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both.  Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.

Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket.  The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors.  This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.

In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def.  This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.

4b42df5da8 Merge branch 'bond_neigh_parms'
Veaceslav Falico says:

====================
Recent patches revealed an old bug, which was there for quite awhile. It's
related to vlan on top of bonding and ndo_neigh_setup(). When vlan device
is initiated, it calls its real_dev->ndo_neigh_setup(), and in case of
bonding - it will modify neigh_parms->neigh_setup to point to
bond_neigh_init, while neigh_parms are of vlan's dev.

This way, when neigh_parms->neigh_setup() of vlan's dev is called, the
bonding function will be called, which expects the dev to be struct
bonding, but will receive a vlan dev.

It was hidden before because of bond->first_slave usage. Now, with
Nikolay's conversion to list/RCU, first_slave is gone and we hit a null
pointer dereference when working with lists/slave.

First patch moves ndo_neigh_setup() in neigh_parms_alloc() to the bottom,
so that the ->dev will be available to the caller. It doesn't really change
anything, however is needed for the second patch.

Second patch makes bond_neigh_setup() (bond->ndo_neigh_setup()) check if
the neigh_parms are really from a bonding dev, and only modify the
neigh_setup in this case.
