The patch adds empty function of_get_property for non-dt build, so that
drivers migrating to dt can save some '#ifdef CONFIG_OF'.
This also fixes the current Tegra compile problem in linux-next.

The check_bytes() function is used by slub debugging. It returns a pointer
to the first unmatching byte for a character in the given memory area.
If the character for matching byte is greater than 0x80, check_bytes()
doesn't work. Becuase 64-bit pattern is generated as below.
value64 = value | value << 8 | value << 16 | value << 24;
value64 = value64 | value64 << 32;
The integer promotions are performed and sign-extended as the type of value
is u8. The upper 32 bits of value64 is 0xffffffff in the first line, and
the second line has no effect.
This fixes the 64-bit pattern generation.

match_held_lock() was assuming it was being called on a lock class
that had already seen usage.
This condition was true for bug-free code using lockdep_assert_held(),
since you're in fact holding the lock when calling it. However the
assumption fails the moment you assume the assertion can fail, which
is the whole point of having the assertion in the first place.
Anyway, now that there's more lockdep_is_held() users, notably
__rcu_dereference_check(), its much easier to trigger this since we
test for a number of locks and we only need to hold any one of them to
be good.

With the UM_SIGNAL alignment fault mode, no siginfo structure is
passed to userspace.
POSIX specifies how siginfo_t should be populated for alignment
faults, so this patch does just that:
* si_signo = SIGBUS
* si_code = BUS_ADRALN
* si_addr = misaligned data address at which access was attempted

access model
Currently, it's possible to set the kernel to ignore alignment
faults when changing the alignment fault handling mode at runtime
via /proc/sys/alignment, even though this is undesirable on ARMv6
and above, where it can result in infinite spins where an un-fixed-
up instruction repeatedly faults.
In addition, the kernel clobbers any alignment mode specified on
the command-line if running on ARMv6 or above.
This patch factors out the necessary safety check into a couple of
new helper functions, and checks and modifies the fault handling
mode as appropriate on boot and on writes to /proc/cpu/alignment.
Prior to ARMv6, the behaviour is unchanged.
For ARMv6 and above, the behaviour changes as follows:
* Attempting to ignore faults on ARMv6 results in the mode being
forced to UM_FIXUP instead. A warning is printed if this
happened as a result of a write to /proc/cpu/alignment. The
user's UM_WARN bit (if present) is still honoured.
* An alignment= argument from the kernel command-line is now
honoured, except that the kernel will modify the specified mode
as described above. This is allows modes such as UM_SIGNAL and
UM_WARN to be active immediately from boot, which is useful for
debugging purposes.

poison_init_mem() used a loop of:
while ((count = count - 4))
which has 2 problems - an off by one error so that we do one less word
than we should, and the other is that if count == 0 then we loop forever
and poison too much. On a platform with HAVE_TCM=y but nothing in the
TCM's, this caused corruption and the platform failed to boot.

The file mm/proc-arm946.S contains a typo and is missing a structure
member in __arm946_proc_info. The former prevents compilation
and the latter causes problems during boot. It is likely this
file was manually copied from a similar file and not tested, then
later updates to the *_proc_info structures missed this file.
This patch will apply (with offset) with or without the
recent macro unification work that has been done in this directory.
This was verified against linux-next/stable last week.

Two issues were preventing module snd-soc-tegra-wm8903.ko from being
removed and re-inserted:
a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must
be freed before snd_soc_unregister_card() is called, because that
triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which
then fails if any of the GPIOs are in use. To solve this, free all GPIOs
first, so the code doesn't care where they come from.
b) We need to call snd_soc_jack_free_gpios() to match the call to
snd_soc_jack_add_gpios() during initialization. Without this, the
call to snd_soc_jack_add_gpios() fails during any subsequent modprobe
and initialization, since the GPIO and IRQ are already registered. In
turn, this causes the headphone state not to be monitored, so the
headphone is assumed not to be plugged in, and the audio path to it is
never enabled.

CPT pipe select is different from previous generations (using two bits
instead of one). All of the paths from intel_disable_pch_ports were
not making this distinction.
Mode setting with pipe A turned off would then also force all outputs
on pipe B to get turned off as the disable code would mistakenly
decide that all of these outputs were on pipe A and turn them off.

needs to be shifted too
the recent addition of the FT232H showed that baudrate was set wrong. See
gmane.linux.usb.general: "[ftdi_sio] FT232H support". With the old code,
the MSB of the 4 encoded fractional divider bits and more important the
clock predivider bits got lost. Adding the FT232H to the code patch were
these bits are shifted solves the problem. I verified baud rates with a
scope now.
I suspect, that the BM device probably needs these bits shifted too. But
there is no predivider bit, so this is not obvious, and a missing MSB of the
encoded fractional divider only shifts the resulting baudrate minimal.
The AM has only 3 bits of encoded fractional divider, so it is not impacted.
I have no BM device to test, so I only added a comment and left the code for
the BM untouched.

The sequence to put port in test mode is not complete.
According EHCI specification all enabled ports must be
put in suspend.

Even if it's unlikely for this to cause an error,
there is a typo in the code that uses the bitwise-AND
operator instead of the logical one.

Connecting the V2M to a Linux host results in a constant stream of
errors spammed to the console, all of the form
sd 1:0:0:0: ioctl_internal_command return code = 8070000
: Sense Key : 0x4 [current]
: ASC=0x0 ASCQ=0x0
The errors appear to be otherwise harmless. Add an unusual_devs entry
which eliminates all of the error messages.

As cpu_is_mx stuff is being used in the driver, header mach/hardware.h
should be explicitly included.
The missing of the header is causing today's linux-next build error
as bleow.
