a5d4506d07 ARM: 8016/1: Check cpu id in pj4_cp0_init.
Check cpu id in pj4_cp0_init. So for no-PJ4 V7 cpus,
pj4_cpu0_init just return.
This fix will help to make the all the V7 cpus(PJ4 and no-PJ4)
can use code.

fdb487f5c9 ARM: 8015/1: Add cpu_is_pj4 to distinguish PJ4 because it has some differences with V7
The patch add cpu_is_pj4 at arch/arm/include/asm/cputype.h
PJ4 has some differences with V7, for example the coprocessor.
To disinguish this kind of situation. cpu_is_pj4 is needed.

7563487cbf isdnloop: several buffer overflows
There are three buffer overflows addressed in this patch.

1) In isdnloop_fake_err() we add an 'E' to a 60 character string and
then copy it into a 60 character buffer.  I have made the destination
buffer 64 characters and I'm changed the sprintf() to a snprintf().

2) In isdnloop_parse_cmd(), p points to a 6 characters into a 60
character buffer so we have 54 characters.  The ->eazlist[] is 11
characters long.  I have modified the code to return if the source
buffer is too long.

3) In isdnloop_command() the cbuf[] array was 60 characters long but the
max length of the string then can be up to 79 characters.  I made the
cbuf array 80 characters long and changed the sprintf() to snprintf().
I also removed the temporary "dial" buffer and changed it to use "p"
directly.

Unfortunately, we pass the "cbuf" string from isdnloop_command() to
isdnloop_writecmd() which truncates anything over 60 characters to make
it fit in card->omsg[].  (It can accept values up to 255 characters so
long as there is a '\n' character every 60 characters).  For now I have
just fixed the memory corruption bug and left the other problems in this
driver alone.

79192ca8eb scripts: objdiff: detect object code changes between two commits
objdiff is useful when doing large code cleanups.  For example, when
removing checkpatch warnings and errors from new drivers in the staging
tree.

objdiff can be used in conjunction with a git rebase to confirm that
each commit made no changes to the resulting object code.  It has the
same return values as diff(1).

This was written specifically to support adding the skein and threefish
cryto drivers to the staging tree.  I needed a programmatic way to
confirm that commits changing >90% of the lines didn't inadvertently
change the code.

Temporary files (objdump output) are stored in

  /path/to/linux/.tmp_objdiff

'make mrproper' will remove this directory.

ef33bc3217 ASoC: fsl_sai: Fix Bit Clock Polarity configurations
The BCP bit in TCR4/RCR4 register rules as followings:
  0 Bit clock is active high with drive outputs on rising edge
    and sample inputs on falling edge.
  1 Bit clock is active low with drive outputs on falling edge
    and sample inputs on rising edge.

For all formats currently supported in the fsl_sai driver, they're exactly
sending data on the falling edge and sampling on the rising edge.

However, the driver clears this BCP bit for all of them which results click
noise when working with SGTL5000 and big noise with WM8962.

Thus this patch corrects the BCP settings for all the formats here to fix
the nosie issue.

553f809e23 arm, kvm: fix double lock on cpu_add_remove_lock
Commit 8146875de7 (arm, kvm: Fix CPU hotplug callback registration)
holds the lock before calling the two functions:

	kvm_vgic_hyp_init()
	kvm_timer_hyp_init()

and both the two functions are calling register_cpu_notifier()
to register cpu notifier, so cause double lock on cpu_add_remove_lock.

Considered that both two functions are only called inside
kvm_arch_init() with holding cpu_add_remove_lock, so simply use
__register_cpu_notifier() to fix the problem.

Commit 8fc1b0f87d ("ARM: qcom: Split Qualcomm support into legacy and

Three Kconfig symbols used to depend on ARCH_MSM_DT: ARCH_MSM8X60,
ARCH_MSM8960, and ARCH_MSM8974. These three symbols now depend on
ARCH_QCOM. So it appears this driver needs to depend on ARCH_QCOM too.

dcb32ecd9a ALSA: hda - Do not assign streams in reverse order
Currently stream numbers are assigned in reverse order.

Unfortunately commit 7546abfb8e ("ALSA: hda - Increment
default stream numbers for AMD HDMI controllers") assumed this was not
the case (specifically, it had the "old cards had single device only"
=> "extra unused stream numbers do not matter" assumption), causing
non-working audio regressions for AMD Radeon HDMI users.

Change the stream numbers to be assigned in forward order.

The benefit is that regular audio playback will still work even if the
assumed stream count is too high, downside is that a too high stream
count may remain hidden.

749e8be71d thermal: imx: update formula for thermal sensor
Thermal sensor used to need two calibration points which are
in fuse map to get a slope for converting thermal sensor's raw
data to real temperature in degree C. Due to the chip calibration
limitation, hardware team provides an universal formula to get
real temperature from internal thermal sensor raw data:

Slope = 0.4297157 - (0.0015976 * 25C fuse);

Update the formula, as there will be no hot point calibration
data in fuse map from now on.

c39b06951f DRM: armada: fix corruption while loading cursors
Loading cursors to the LCD controller's SRAM can be corrupted when the
configured pixel clock is relatively slow.  This seems to be caused
when we write back-to-back to the SRAM registers.

There doesn't appear to be any status register we can read to check
when an access has completed.

Inserting a dummy read between the writes appears to fix the problem.
