The CPSW switch can act as Dual EMAC by segregating the switch ports
using VLAN and port VLAN as per the TRM description in
14.3.2.10.2 Dual Mac Mode
Following CPSW components will be common for both the interfaces.
* Interrupt source is common for both eth interfaces
* Interrupt pacing is common for both interfaces
* Hardware statistics is common for all the ports
* CPDMA is common for both eth interface
* CPTS is common for both the interface and it should not be enabled on
both the interface as timestamping information doesn't contain port
information.
Constrains
* Reserved VID of One port should not be used in other interface which will
enable switching functionality
* Same VID must not be used in both the interface which will enable switching
functionality

The original suggestion to delete wanrouter started earlier
with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.
More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39c3 ("netdevice wanrouter: Convert directly reference of
netdev->priv"). So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.
This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.
Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Define the 2.12 bzImage boot protocol: add xloadflags and additional
fields to allow the command line, initramfs and struct boot_params to
live above the 4 GiB mark.
The xloadflags now communicates if this is a 64-bit kernel with the
legacy 64-bit entry point and which of the EFI handover entry points
are supported.
Avoid adding new read flags to loadflags because of claimed
bootloaders testing the whole byte for == 1 to determine bzImageness
at least until the issue can be researched further.

====================
This batch contains netfilter updates for you net-next tree, they are:
* The new connlabel extension for x_tables, that allows us to attach
labels to each conntrack flow. The kernel implementation uses a
bitmask and there's a file in user-space that maps the bits with the
corresponding string for each existing label. By now, you can attach
up to 128 overlapping labels. From Florian Westphal.
* A new round of improvements for the netns support for conntrack.
Gao feng has moved many of the initialization code of each module
of the netns init path. He also made several code refactoring, that
code looks cleaner to me now.
* Added documentation for all possible tweaks for nf_conntrack via
sysctl, from Jiri Pirko.
* Cisco 7941/7945 IP phone support for our SIP conntrack helper,

Before attempting to activate a RAID array, it is checked for sufficient
redundancy. That is, we make sure that there are not too many failed
devices - or devices specified for rebuild - to undermine our ability to
activate the array. The current code performs this check twice - once to
ensure there were not too many devices specified for rebuild by the user
('validate_rebuild_devices') and again after possibly experiencing a failure
to read the superblock ('analyse_superblocks'). Neither of these checks are
sufficient. The first check is done properly but with insufficient
information about the possible failure state of the devices to make a good
determination if the array can be activated. The second check is simply
done wrong in the case of RAID10 because it doesn't account for the
independence of the stripes (i.e. mirror sets). The solution is to use the
properly written check ('validate_rebuild_devices'), but perform the check
after the superblocks have been read and we know which devices have failed.
This gives us one check instead of two and performs it in a location where
it can be done right.
Only RAID10 was affected and it was affected in the following ways:
- the code did not properly catch the condition where a user specified
a device for rebuild that already had a failed device in the same mirror
set. (This condition would, however, be caught at a deeper level in MD.)
- the code triggers a false positive and denies activation when devices in
independent mirror sets have failed - counting the failures as though they
were all in the same set.
The most likely place this error was introduced (or this patch should have
been included) is in commit 4ec1e369 - first introduced in v3.7-rc1.
Consequently this fix should also go in v3.7.y, however there is a
small conflict on the .version in raid_target, so I'll submit a
separate patch to -stable.

Paul Gortmaker says:
====================
The Ethernet-HowTo was maintained for roughly 10 years, from 1993 to 2003.
Fortunately sane hardware probing and auto detection (via PCI and ISA/PnP)
largely made the document a relic of the past, hence it being abandoned
a decade ago.
However, there is one last useful thing that we can extract from the
effort made in maintaining that document. We can use it to guide us
with respect to what rare, experimental and/or super ancient 10Mbit
ISA drivers don't make sense to maintain in-tree anymore.
Nobody will argue that ISA is obsolete. Availability went away at about
the time Pentium3 motherboards moved from 500MHz Slot1/SECC processors
to the green 500MHz Socket 370 Pentium3 chips, at the turn of the century.
In theory, it is possible that someone could still be running one of these
12+ year old P3 machines and want 3.9+ bleeding edge kernels (but unlikely).
In light of the above (remote) possibility, we can defer the removal of some
ISA network drivers that were highly popular and well tested. Typically
that means the stuff more from the mid to late '90s, some with ISA PnP
support, like the 3c509, the wd/SMC 8390 based stuff, PCnet/lance etc.
But a lot of other drivers, typically from the early 1990s were for rare
hardware, and experimental (to the point of requiring a cron job that would
do a test ping, and then ifconfig down/up and/or a rmmod/insmod!). And
some of these drivers (znet, and lp486e to name two) are physically tied
to platforms with on motherboard ethernet -- of 486 machines that date
from the early 1990s and can only have single digit amounts of memory.
What I'd like to achieve here with this series, is to get rid of those old
drivers that are no longer being used. In an earlier discussion where
I'd proposed deleting a single driver, Alan suggested we instead dump
all the historical stuff in one go, to make it "...immediately obvious
where the break point is..."[1] and that it was "perfectly reasonable it
(and a pile of other ISA cards) ought to be shown the door"[2]. So that
is the goal here - make a clear line in the sand where the really ancient
stuff finally gets kicked to the curb.
Two old parallel port drivers are considered for removal here as well,
since in early 386/486 ISA machines, the parallel port was typically found
with the UARTS on the multi-I/O ISA controller card. These drivers also date
from the early 1990's; parallel ports are no longer found on modern boards,
and their performance was not even capable of 10% of 10Mbit bandwidth.
Allow me a preemptive justification against the inevitable comments from
well meaning bystanders who suggest "why not just leave all this alone?".
Dead drivers cost us all if they are left in tree. If you think that
is false, then please first consider:
-every time you type "git status", you are checking to see if modifications
have been made by you to all that dead code.
-every time you type "git grep <regex>" you are searching through files
which contain that dead code that simply does not interest you.
-every time you build a "allyesconfig" and an "allmodconfig" (don't tell
me you skip this step before submitting your changes to a maintainer),
you waste CPU cycles building this dead code.
-every time there is a tree wide API change, or cleanup, or file relocation,
we pay the cost of updating dead code, or moving dead code.
-daily regression tests (take linux-next as the most transparent
example) spend time building (and possibly running) this dead code.
-hard working people who regularly run auditing tools looking for lurking
bugs (sparse/coverity/smatch/coccinelle) are wasting time checking for,
and fixing bugs in this dead code.
This last one is key. Please take a look at the git history for the
files that are proposed for removal here. Look at the git history for
any one of them ("git whatchanged --follow drivers/net/.../driver.c")
Mentally sort the changes into two bins -- (1) the robotic tree-wide
changes, and (2) the "look I found a real run-time bug while using this"
category. You will see that category #2 is essentially empty.
Further to that, realize that drivers don't simply disappear. We are
not operating in the binary-only distribution space like other OS. All
these drivers remain in the git history forever. If a person is an
enthusiast for extreme legacy hardware, they are probably already
customizing their kernel source and building it themselves to support
such systems. Also keep in mind that they could still build the 3.8
kernel exactly as-is, and run it (or a 3.8.x stable variant of it) for
several more years if they were really determined to cling to these old
experimental ISA drivers for some reason.
In summary, I hope that folks can be pragmatic about this, and not
get swept up in nostalgia. Ask yourself whether it is realistic to
expect a person would have a genuine use case where they would
need to build a 3.9+ modern kernel and install it on some legacy hardware
that has no option but to absolutely _require_ one of the drivers
that are deleted here.
The following series was created with --irreversible-delete for
ease of review (it skips showing the content of files that are
deleted); however the complete patches can be pulled as per below.

Since we have removed NCE (Neighbour Cache Entry) reference from
routing entries, the only refcnt holders of an NCE are its timer
(if running) and its owner table, in usual cases. As a result,
neigh_periodic_work() purges NCEs over and over again even for
gateways.
It does not make sense to purge entries, if number of them is
very small, so keep them. The minimum number of entries to keep
is specified by gc_thresh1.

The parallel port is largely replaced by USB, and even in the
day where these drivers were current, the documented speed was
less than 100kB/s. Let us not pretend that anyone cares about
these drivers anymore, or worse - pretend that anyone is using
them on a modern kernel.
As a side bonus, this is the end of legacy parallel port ethernet,
so we get to drop the whole chunk relating to that in the legacy
Space.c file containing the non-PCI unified probe dispatch.

The original intent of this file was to list limitations in
drivers/hardware relating to multicast use, back when some
modest hardware from the early 1990s did not support things
we might take for granted today.
I was intending to delete some now-gone MCA/token ring entries
in this file, but once I opened it, I found it only contained
information on the earliest (pre-2000) linux networking drivers.
Checking the git history shows that the file hasn't been touched
since 2005. Clearly nobody is actively consulting this file
as a meaningful reference.
Rather than add a "YES YES YES" line for all of the drivers we
currently have, lets just take advantage of the fact that nobody
is using the file to delete it.
This has the side benefit of not having to do a line-by-line
deletion of the file content as each older driver is expired.

While a privileged program can open a raw socket, attach some
restrictive filter and drop its privileges (or send the socket to an
unprivileged program through some Unix socket), the filter can still
be removed or modified by the unprivileged program. This commit adds a
socket option to lock the filter (SO_LOCK_FILTER) preventing any
modification of a socket filter program.
This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even
root is not allowed change/drop the filter.
The state of the lock can be read with getsockopt(). No error is
triggered if the state is not changed. -EPERM is returned when a user
tries to remove the lock or to change/remove the filter while the lock
is active. The check is done directly in sk_attach_filter() and
sk_detach_filter() and does not affect only setsockopt() syscall.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

The as-documented rcu_nocb_poll will fail to enable this feature
for two reasons. (1) there is an extra "s" in the documented
name which is not in the code, and (2) since it uses module_param,
it really is expecting a prefix, akin to "rcutree.fanout_leaf"
and the prefix isn't documented.
However, there are several reasons why we might not want to
simply fix the typo and add the prefix:
1) we'd end up with rcutree.rcu_nocb_poll, and rather probably make
a change to rcutree.nocb_poll
2) if we did #1, then the prefix wouldn't be consistent with the
rcu_nocbs=<cpumap> parameter (i.e. one with, one without prefix)
3) the use of module_param in a header file is less than desired,
since it isn't immediately obvious that it will get processed
via rcutree.c and get the prefix from that (although use of
module_param_named() could clarify that.)
4) the implied export of /sys/module/rcutree/parameters/rcu_nocb_poll
data to userspace via module_param() doesn't really buy us anything,
as it is read-only and we can tell if it is enabled already without
it, since there is a printk at early boot telling us so.
In light of all that, just change it from a module_param() to an
early_setup() call, and worry about adding it to /sys later on if
we decide to allow a dynamic setting of it.
Also change the variable to be tagged as read_mostly, since it
will only ever be fiddled with at most, once at boot.

Currently, the PM core disables runtime PM for all devices right
after executing subsystem/driver .suspend() callbacks for them
and re-enables it right before executing subsystem/driver .resume()
callbacks for them. This may lead to problems when there are
two devices such that the .suspend() callback executed for one of
them depends on runtime PM working for the other. In that case,
if runtime PM has already been disabled for the second device,
the first one's .suspend() won't work correctly (and analogously
for resume).
To make those issues go away, make the PM core disable runtime PM
for devices right before executing subsystem/driver .suspend_late()
callbacks for them and enable runtime PM for them right after
executing subsystem/driver .resume_early() callbacks for them. This
way the potential conflitcs between .suspend_late()/.resume_early()
and their runtime PM counterparts are still prevented from happening,
but the subtle ordering issues related to disabling/enabling runtime
PM for devices during system suspend/resume are much easier to avoid.

Add 3 new variables and sysctls to tune them (by one "next_id" variable
for messages, semaphores and shared memory respectively). This variable
can be used to set desired id for next allocated IPC object. By default
it's equal to -1 and old behaviour is preserved. If this variable is
non-negative, then desired idr will be extracted from it and used as a
start value to search for free IDR slot.
Notes:
1) this patch doesn't guarantee that the new object will have desired
id. So it's up to user space how to handle new object with wrong id.
2) After a sucessful id allocation attempt, "next_id" will be set back
to -1 (if it was non-negative).

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from the kernel documentation.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
