The code that provides /dev/mem uses xlate_dev_mem_{k,}ptr() to
avoid making a cachable mapping of a non-cachable area on ia64.
On arm64 we do this via phys_mem_access_prot() instead, but provide
dummy versions of xlate_dev_mem_{k,}ptr().
These are the same as those in asm-generic/io.h, which we include from
asm/io.h

Commit 833f2cbf70 ("ARM: dts: imx6: change the core clock of spdif")
changed many more clocks than only the SPDIF core clock as stated in
the commit message.
The MLB clock has been added and this causes SPDIF regression as
reported by Xavi Drudis Ferran and also in this forum post:
https://forum.digikey.com/thread/34240
The MX6Q Reference Manual does not mention that MLB is a clock related
to SPDIF, so change it back to a dummy clock to restore SPDIF
functionality.
Thanks to Ambika for providing the fix at:

As NMIs can also cause latency when interrupts are disabled, the hwlat
detectory has no way to know if the latency it detects is from an NMI or an
SMI or some other hardware glitch.
As ftrace_nmi_enter/exit() funtions are no longer used (except for sh, which
isn't supported anymore), I converted those to "arch_ftrace_nmi_enter/exit"
and use ftrace_nmi_enter/exit() to check if hwlat detector is tracing or
not, and if so, it calls into the hwlat utility.
Since the hwlat detector only has a single kthread that is spinning with
interrupts disabled, it marks what CPU it is on, and if the NMI callback
happens on that CPU, it records the time spent in that NMI. This is added to
the output that is generated by the hwlat detector as:
#3 inner/outer(us): 9/9 ts:1470836488.206734548
#4 inner/outer(us): 0/8 ts:1470836497.140808588
#5 inner/outer(us): 0/6 ts:1470836499.140825168 nmi-total:5 nmi-count:1
#6 inner/outer(us): 9/9 ts:1470836501.140841748
All time is still tracked in microseconds.
The NMI information is only shown when an NMI occurred during the sample.

Łukasz Daniluk reported that on a RHEL kernel that his machine would lock up
after enabling function tracer. I asked him to bisect the functions within
available_filter_functions, which he did and it came down to three:
_paravirt_nop(), _paravirt_ident_32() and _paravirt_ident_64()
It was found that this is only an issue when noreplace-paravirt is added
to the kernel command line.
This means that those functions are most likely called within critical
sections of the funtion tracer, and must not be traced.
In newer kenels _paravirt_nop() is defined within gcc asm(), and is no
longer an issue. But both _paravirt_ident_{32,64}() causes the
following splat when they are traced:

Merge "drop last omap3 board files for v4.8" from Tony Lindgren:
Remove the last two legacy board-*.c files for omap3 for legacy
booting for v4.8 to allow making mach-omap2 device tree only for
v4.9.
We've had Nokia N900 and omap3 LDP board-*.c files remaining
while other omap3 devices have been device tree only for quite
a while now. Also N900 and LDP have had device tree based booting
working for years now, but few drivers for N900 were still only
working in legacy only mode until recently. With the remaining
issues out of the way, we discussed on the mailing lists that
we're finally OK to remove the remaining board-*.c files.
For the timing of this pull request, I wanted to wait until
v4.8-rc1 is out to make sure the legacy booting still works fine
after the merge window before doing it.
And for v4.8, let's not touch any other platform data in case we
still need to revert for some reason. This makes the revert just a
question of adding back the legacy board-*.c files.
Then if no issues, we can remove the unused remaining platform
data later on for v4.9.

Changes to make the resume from cpu_suspend() code behave more like
secondary boot caused debug exceptions to be unmasked early by
__cpu_setup(). We then go on to restore mdscr_el1 in cpu_do_resume(),
potentially taking break or watch points based on uninitialised registers.
Mask debug exceptions in cpu_do_resume(), which is specific to resume
from cpu_suspend(). Debug exceptions will be restored to their original
state by local_dbg_restore() in cpu_suspend(), which runs after
hw_breakpoint_restore() has re-initialised the other registers.

The driver is for a trackpad device so is not needed for booting and
makes more sense to have it as module to reduce the kernel image size.
It was probably enabled as built-in because module autoload was not
working when the I2C device was registered by OF but this got fixed
in commit b7d21058b4 ("Input: atmel_mxt_ts - add maxtouch to I2C
table for module autoload") so it's safe to enable as a module now.
