Move the inclusion of the version 4 cache controller registers so that
it is with all the other register bit flag definitions. This makes it
consistent with the other version core inclusion points, and means we
don't need "#ifdef"ery in odd-ball places for these definitions.

All version 3 based ColdFire CPU cores have a similar cache controller.
Merge all the exitsing definitions into a single file, and make them
similar in style and naming to the existing version 2 and version 4
cache controller definitions.

The version 2 ColdFire CPU based cores all contain a similar cache
controller unit. Create a set of bit flag definitions for the supporting

The more modern ColdFire parts (even if based on older version cores)
have separate user and supervisor stack pointers (a7 register).
Modify the ColdFire CPU setup and exception code to enable and use
this on parts that have it.

There is no need for the DEBUG based command line printing in here.
The kernel will print out the command line in the banner later in
the boot up. So remove it.

There are no users of the old "fasthandler" interrupt entry code.

The ColdFire UART base addresses varies between the different ColdFire
family members. Instead of keeping the base addresses with the UART
definitions keep them with the other addresses definitions for each
ColdFire part.
The motivation for this move is so that when we add new ColdFire
part definitions, they are all in a single file (and we shouldn't
normally need to modify the UART definitions in mcfuart.h at all).

The instruction timings of the ColdFire 54xx family parts are
different to other version 4 parts (or version 2 or 3 parts for
that matter too).
Move the instruction timing setting into the ColdFire part
specific headers, and set the 54xx value appropriately.

Move the ColdFire CPU names out of setup.c and into their repsective
headers. That way when we add new ones we won't need to modify

The Freescale M547x family of ColdFire processors is very similar
to the M548x series. We use all the same support for it. Initially
all we need is a high level configuration option for it.

The ColdFire 547x family of processors is very similar to the ColdFire
548x series. Almost all of the support for them is the same. Make the
code supporting the 548x more gneric, so it will be capable of
supporting both families.
For the most part this is a renaming excerise to make the support
code more obviously apply to both families.

Now that we have meaningfull symbolic constants for bit definitions
of the cache registers of m5407 and m548x chips, use them to
improve readability, portability and efficiency of the cache operations.
This also fixes __flush_cache_all for m548x chips : implicit
DCACHE_SIZE was exact for m5407, but wrong for m548x.

The MCF548x have the same cache control registers as the MCF5407.
Extract the bit definitions for the ACR and CACR registers from m5407sim.h
and move them to a new file m54xxacr.h. Those definitions are not used
anywhere yet, so no other file is involved. This is a preparation for
m54xx cache support cleanup.

The preferred source address is currently ignored for local routes,
which results in all local connections having a src address that is the
same as the local dst address. Fix this by respecting the preferred source
address when it is provided for local routes.
This bug can be demonstrated as follows:
# ifconfig dummy0 192.168.0.1
# ip route show table local | grep local.*dummy0
local 192.168.0.1 dev dummy0 proto kernel scope host src 192.168.0.1
# ip route change table local local 192.168.0.1 dev dummy0 \
proto kernel scope host src 127.0.0.1
# ip route show table local | grep local.*dummy0
local 192.168.0.1 dev dummy0 proto kernel scope host src 127.0.0.1
We now establish a local connection and verify the source IP
address selection:
# nc -l 192.168.0.1 3128 &
# nc 192.168.0.1 3128 &
# netstat -ant | grep 192.168.0.1:3128.*EST

If security_filter_rule_init() doesn't return a rule, then not everything
is as fine as the return code implies.
This bug only occurs when the LSM (eg. SELinux) is disabled at runtime.
Adding an empty LSM rule causes ima_match_rules() to always succeed,
ignoring any remaining rules.
default IMA TCB policy:
# PROC_SUPER_MAGIC
dont_measure fsmagic=0x9fa0
# SYSFS_MAGIC
dont_measure fsmagic=0x62656572
# DEBUGFS_MAGIC
dont_measure fsmagic=0x64626720
# TMPFS_MAGIC
dont_measure fsmagic=0x01021994
# SECURITYFS_MAGIC
dont_measure fsmagic=0x73636673
< LSM specific rule >
dont_measure obj_type=var_log_t
measure func=BPRM_CHECK
measure func=FILE_MMAP mask=MAY_EXEC
measure func=FILE_CHECK mask=MAY_READ uid=0
Thus without the patch, with the boot parameters 'tcb selinux=0', adding
the above 'dont_measure obj_type=var_log_t' rule to the default IMA TCB
measurement policy, would result in nothing being measured. The patch
prevents the default TCB policy from being replaced.

commit bf9ae5386bca8836c16e69ab8fdbe46767d7452a
(llc: use dev_hard_header) removed the
skb_reset_mac_header call from llc_mac_hdr_init.
This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT.
We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns
a meaningful result.

use pskb_may_pull to access ipv6 header correctly for paged skbs
It was omitted in the bridge code leading to crash in blind
__skb_pull
since the skb is cloned undonditionally we also simplify the

Commit 3f5a2a713aad28480d86b0add00c68484b54febc zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed. This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example). We don't want SMB or CMB to change during this
operation.
Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

Before this patch, the following error would sometimes occur after a
resume on pxa3xx:
/path/to/mm/memory.c:144: bad pmd 8040542e.
The problem was that a temporary page table mapping was being improperly
restored.
The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu
to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires
that the r1 register holding the address of this mapping not be
modified, however, resume_turn_on_mmu does modify it. It is mostly
correct in that r1 receives the base table address, but it may also
get other bits in 13:0. This results in pxa3xx_resume_after_mmu
restoring the original mapping to the wrong place, corrupting memory
and leaving the temporary mapping in place.

The commit 6ac6b817f3f4c23c5febd960d8deb343e13af5f3 (ARM: pxa: encode
IRQ number into .nr_irqs) removed definition of ITE_LAST_IRQ which
caused the following build error:

ipchain__fprintf_graph() casts the number of hits in a branch as an
int, which means we lose its highests bits.
This results in meaningless number of callchain hits in perf.data
that have a high number of hits recorded, typically those that have
callchain branches hits appearing more than INT_MAX. This happens
easily as those are pondered by the event period.

Disable preemption in init_ibs(). The function only checks the
ibs capabilities and sets up pci devices (if necessary). It runs
only on one cpu but operates with the local APIC and some MSRs,
thus it is better to disable preemption.

em28xx uses core assisted locking, so it shouldn't use .ioctl.
The .ioctl callback was replaced by .unlocked_ioctl for video nodes,
but not for radio nodes. This is now corrected.

It seems that cx88 and ivtv use wm8775 on some different modes. The
patch that added support for a board with wm8775 broke ivtv boards with
this device. As we're too close to release 2.6.37, let's just revert
it.

This patch fixes a regression that crept into 2.6.36.
The volume control scale in the cx25840 driver has an unusual mapping
from register values to v4l2 volume control values. Enforce the mapping
limits, so that the default volume control setting does not fall out of
bounds to prevent the cx25840 module device probe from failing.

The error message 'NMI watchdog failed to create perf event...'
does not make it clear that this is a fatal error for the
watchdog. It also currently prints the error value as a
pointer, rather than extracting the error code with PTR_ERR().
Fix that.
Add a note to the description of the 'nowatchdog' kernel
parameter to associate it with this message.
