The logic between handling CUSTOM_ERROR and STANDARD_ERROR is just the
reporting style.

So make it generic, simplify and standardize the reporting with both
master and target information printed to log.

Handle the register address difference for master code for standard
error and custom error as well.

While at it, fix a minor indentation error.

As per Documentation (OMAP4+), then masterid is infact encoded as
follows:
"L3_TARG_STDERRLOG_MSTADDR[7:0] STDERRLOG_MSTADDR stores the NTTP
master address. The master address is the concatenation of Prefix &
Initiator ConnID. It is defined on 8 bits. The 6 MSBs are used to
distinguish the different initiators."

So, when we matchup currently with the master ID list, we never get a
proper match other than when MPU is the master (thanks to 0).

Now, on other platforms such as AM437x, this tends to be bits[5:0].

Fix this by using the relevant 6MSBits to identify the master ID for
standard and custom errors.

This allows us to encompass target information and flag mux offset that
points to the target information into a singular structure. This saves
us the need to look up two different arrays indexed by module ID for
information.

This allows us to reduce the static target information allocation to
just the ones that are documented.

DRA7xx SoC has the same l3-noc interconnect ip (as OMAP4 and OMAP5), but
AM437x SoC has just 2 modules instead of 3 which other SoCs have.

So, stop using direct access of array indices and use of->match data and
simplify implementation to benefit future usage.

While at it, rename a few very generic variables to make them omap
specific. This helps us differentiate from DRA7 and AM43xx data in the
future.

NOTE: None of the platforms that use omap_l3_noc are non-device tree
anymore. So, it is safe to assume OF match here.

On DRA7, unlike on OMAP4 and OMAP5, the flag mux input numbers used
to indicate the source of errors are not continous. Have a way in the
driver to catch these and WARN the user of the flag mux input thats
either undocumented or wrong.

In the similar vein, Timeout errors in AM43x can't be cleared per h/w
team, neither does it have a STDERRLOG_MAIN to clear the error.

Further, the mux bit offset might not even be indexed into our array
of known mux input description, in which case we'd have a abort.

So, define a static range check for bit description and any definition
which has target_name set to NULL (the ones that are not populated or
ones that are specifically marked in the case of discontinous input
numbers), can handle the same gracefully. Upon occurance of error from
such sources, mask it. Otherwise, we'd have an infinite interrupt
source without any means to clear it.

NOTE: follow on patch ensures that these masked bits are ignored.

Currently the target instance information is organized indexed by bit
field offset into multiple arrays.

1. We currently have offsets specific to each target associated with each
clock domains are in seperate arrays:

l3_targ_inst_clk1
l3_targ_inst_clk2
l3_targ_inst_clk3

2. Then they are organized per master index in l3_targ.

3. We have names in l3_targ_inst_name as an array to array of strings
corresponding to the above with offsets.

Simplify the same by defining a structure for information containing
both target offset and name. this is then stored in arrays per domain
and organized into an array indexed off domain.

The array is still indexed based on bit field offset.

It its possible to configure your PAM stack to refuse login if audit
messages (about the login) were unable to be sent.  This is common in
many distros and thus normal configuration of many containers.  The PAM
modules determine if audit is enabled/disabled in the kernel based on
the return value from sending an audit message on the netlink socket.
If userspace gets back ECONNREFUSED it believes audit is disabled in the
kernel.  If it gets any other error else it refuses to let the login
proceed.

Just about ever since the introduction of namespaces the kernel audit
subsystem has returned EPERM if the task sending a message was not in
the init user or pid namespace.  So many forms of containers have never
worked if audit was enabled in the kernel.

BUT if the container was not in net_init then the kernel network code
would send ECONNREFUSED (instead of the audit code sending EPERM).  Thus
by pure accident/dumb luck/bug if an admin configured the PAM stack to
reject all logins that didn't talk to audit, but then ran the login
untility in the non-init_net namespace, it would work!! Clearly this was
a bug, but it is a bug some people expected.

With the introduction of network namespace support in 3.14-rc1 the two
bugs stopped cancelling each other out.  Now, containers in the
non-init_net namespace refused to let users log in (just like PAM was
configfured!) Obviously some people were not happy that what used to let
users log in, now didn't!

This fix is kinda hacky.  We return ECONNREFUSED for all non-init
relevant namespaces.  That means that not only will the old broken
non-init_net setups continue to work, now the broken non-init_pid or
non-init_user setups will 'work'.  They don't really work, since audit
isn't logging things.  But it's what most users want.

In 3.15 we should have patches to support not only the non-init_net
(3.14) namespace but also the non-init_pid and non-init_user namespace.
So all will be right in the world.  This just opens the doors wide open
on 3.14 and hopefully makes users happy, if not the audit system...

If a new (id == -1) ff effect was uploaded from userspace,
ff-core.c::input_ff_upload() will have assigned a positive number to the
new effect id.  Currently, evdev.c::evdev_do_ioctl() will save this new id
to userspace, regardless of whether the upload succeeded or not.

On upload failure, this can be confusing because the dev->ff->effects[]
array will not contain an element at the index of that new effect id.

This patch fixes this by leaving the id unchanged after upload fails.

Note: Unfortunately applications should still expect changed effect id for
quite some time.

Olivier Bonvalet reported having repeated crashes due to a failed
assertion he was hitting in rbd_img_obj_callback():

    Assertion failure in rbd_img_obj_callback() at line 2165:
	rbd_assert(which >= img_request->next_completion);

With a lot of help from Olivier with reproducing the problem
we were able to determine the object and image requests had
already been completed (and often freed) at the point the
assertion failed.

There was a great deal of discussion on the ceph-devel mailing list
about this.  The problem only arose when there were two (or more)
object requests in an image request, and the problem was always
seen when the second request was being completed.

The problem is due to a race in the window between setting the
"done" flag on an object request and checking the image request's
next completion value.  When the first object request completes, it
checks to see if its successor request is marked "done", and if
so, that request is also completed.  In the process, the image
request's next_completion value is updated to reflect that both
the first and second requests are completed.  By the time the
second request is able to check the next_completion value, it
has been set to a value *greater* than its own "which" value,
which caused an assertion to fail.

Fix this problem by skipping over any completion processing
unless the completing object request is the next one expected.
Test only for inequality (not >=), and eliminate the bad
assertion.

When the vlan filtering is enabled on the bridge, but
the filter is not configured on the bridge device itself,
running tcpdump on the bridge device will result in a
an Oops with NULL pointer dereference.  The reason
is that br_pass_frame_up() will bypass the vlan
check because promisc flag is set.  It will then try
to get the table pointer and process the packet based
on the table.  Since the table pointer is NULL, we oops.
