The TSENS block inside the 8996 is internally classified as version 2 of
the IP. Several other SoC families use this block and can share this code.
We rename get_temp() to reflect that it can be used across the v2 family.

There are two banks of registers for v2 TSENS IPs: SROT and TM. On older
SoCs these were contiguous, leading to DTs mapping them as one register
address space of size 0x2000. In newer SoCs, these two banks are not
contiguous anymore.
Add logic to init_common() to differentiate between old and new DTs and
adjust associated offsets for the TM register bank so that the old DTs will
continue to function correctly.

We want to create common code for v2 of the TSENS IP block that is used in
a large number of Qualcomm SoCs. "qcom,tsens-v2" should be able to handle
most of the common functionality start with a common get_temp() function.
It is also necessary to split out the memory regions for the TM and SROT
register banks because their offsets are not constant across SoC families.

When registering the hwmon device, we pass NULL as the device.
While this doesn't result in any immediate breakage, it leaves
the hwmon device at the root of the virtual devices, rather than
attached to the thermal zone hierarchy.
Instead, let's pass the actual device, which is part of the
thermal_zone_device structure. This also avoids the rather
unpleasant ""NULL device *" which can be generated by dev_{err,info}
in the hwmon subsystem.

My Chromebook Plus (kevin) is spitting the following at boot time:
(NULL device *): hwmon: 'sbs-9-000b' is not a valid name attribute, please fix
Clearly, __hwmon_device_register is unhappy about the property name.
Some investigation reveals that thermal_add_hwmon_sysfs doesn't
sanitize the name of the attribute.
In order to keep it quiet, let's replace '-' with '_' in hwmon->type
This is consistent with what iio-hwmon does since b92fe9e337.

MVEBU thermal IP supports multiple channels. Each channel may have
several sensors but for now each channel is wired to only one thermal
sensor. The first channel always points to the so called internal
sensor, within the thermal IP. There is usually one more channel (with
one sensor each time) per CPU. The code has been written to support
possible evolutions of the ap806 IP that would embed more CPUs and thus
more channels to select. Each channel should be referenced in the device
tree as an independent thermal zone.
Add the possibility to read each of these sensors through sysfs by
registering all the sensors (translated in "thermal_zone"). Also add a
mutex on these accesses to avoid read conflicts (only one channel/sensor
may be selected and read at a time).

Current use of thermal_zone_device_register() triggers a warning at boot

Until recently, only one register was referenced in MVEBU thermal IP
node. Recent changes added a second entry pointing to another
register right next to it. We cannot know for sure that we will not
have to access other registers. That will be actually the case when
overheat interrupt feature will come, where it will be needed to access
DFX registers in the same area.
This approach is not scalable so instead of adding consinuously memory
areas in the DT (and change the DT bindings, while keeping backward
compatibility), move the thermal node into a wider syscon from which it
will be possible to also configure the thermal interrupt.

Merge tag 'for-linus-20180629' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.
Anyway, outside of that, this pull contains:
- clone of request with special payload fix (Bart)
- drbd discard handling fix (Bart)
- SATA blk-mq stall fix (me)
- chunk size fix (Keith)
- double free nvme rdma fix (Sagi)"
* tag 'for-linus-20180629' of git://git.kernel.dk/linux-block:
sg: remove ->sg_magic member
drbd: Fix drbd_request_prepare() discard handling
blk-mq: don't queue more if we get a busy return
block: Fix cloning of requests with a special payload
nvme-rdma: fix possible double free of controller async event buffer
block: Fix transfer when chunk sectors exceeds max
Two regression fixes, and a new syscall wire-up.
A fix for the recent conversion to time64_t in the powermac RTC routines, which
caused time to go backward.
Another fix for fallout from the split PMD PTL conversion.
Wire up the new io_pgetevents() syscall.

Aneesh Kumar K.V, Arnd Bergmann, Breno Leitao, Mathieu Malaterre.

As suggested by Nick Piggin it seems we can drop the -ffunction-sections
compile flag, now that the kernel uses thin archives. Testing with 32-
and 64-bit kernel showed no difference in kernel size.

This was introduced more than a decade ago when sg chaining was
added, but we never really caught anything with it. The scatterlist
entry size can be critical, since drivers allocate it, so remove
the magic member. Recently it's been triggering allocation stalls
and failures in NVMe.
