All uses of the current_fs_time() function have been replaced by other
time interfaces.
And, its use cases can be fulfilled by current_time() or ktime_get_*
variants.

Userspace prefers the driver having a status property over having to guess
itself. Specifically this will properly make the GNOME3 UI (and likely
others) properly show discharging / charging / full status, instead
of always showing discharging as status.
Note that in the case there is no charger driver supplying the max17042,
then a status of unknown will get returned. At least upower treats
this the same as not having a status attribute, so in this case nothing
changes from a userspace pov.

Some x86 machines use a max17047 fuel-gauge and x86 might be missing
platform_data if not provided by SFI.
This commit adds default platform_data as fallback option so that the
driver can work on boards where no platform_data is provided.
Since not all boards have a thermistor hooked up, set temp_min to 0 and
change the health checks from temp <= temp_min to temp < temp_min to
not trigger on such boards (where temp reads 0).

Pull thermal management updates from Zhang Rui:
- Fix a problem where orderly_shutdown() is called for multiple times
due to multiple critical overheating events raised in a short period
by platform thermal driver. (Keerthy)
- Introduce a backup thermal shutdown mechanism, which invokes
kernel_power_off()/emergency_restart() directly, after
orderly_shutdown() being issued for certain amount of time(specified
via Kconfig). This is useful in certain conditions that userspace may
be unable to power off the system in a clean manner and leaves the
system in a critical state, like in the middle of driver probing
phase. (Keerthy)
- Introduce a new interface in thermal devfreq_cooling code so that the
driver can provide more precise data regarding actual power to the
thermal governor every time the power budget is calculated. (Lukasz
Luba)
- Introduce BCM 2835 soc thermal driver and northstar thermal driver,
within a new sub-folder. (Rafał Miłecki)
- Introduce DA9062/61 thermal driver. (Steve Twiss)
- Remove non-DT booting on TI-SoC driver. Also add support to fetching
coefficients from DT. (Keerthy)

This patch adds another parameter to the trace function:
trace_thermal_power_devfreq_get_power().
In case when we call directly driver's code for the real power,
we do not have static/dynamic_power values. Instead we get total
power in the '*power' value. The 'static_power' and
'dynamic_power' are set to 0.
Therefore, we have to trace that '*power' value in this scenario.

This patch introduces a new interface for device drivers connected to
devfreq_cooling in the thermal framework: get_real_power().
Some devices have more sophisticated methods (like power counters)
to approximate the actual power that they use.
In the previous implementation we had a pre-calculated power
table which was then scaled by 'utilization'
('busy_time' and 'total_time' taken from devfreq 'last_status').
With this new interface the driver can provide more precise data
regarding actual power to the thermal governor every time the power
budget is calculated. We then use this value and calculate the real
resource utilization scaling factor.

Fixes for 4.12. This is a bit bigger than usual since it's 3 weeks
worth of fixes and most of these changes are for vega10 which is
new for 4.12 and still in a fair amount of flux. It looks like
you missed my last pull request, so those patches are included here
as well. Highlights:
- Lots of vega10 fixes
- Fix interruptable wait mixup
- Fan control method fixes
- Misc display fixes for radeon and amdgpu

Pull SCSI target updates from Nicholas Bellinger:
"Things were a lot more calm than previously expected. It's primarily
fixes in various areas, with most of the new functionality centering
around TCMU backend driver work that Xiubo Li has been driving.
Here's the summary on the feature side:
- Make T10-PI verify configurable for emulated (FILEIO + RD) backends
(Dmitry Monakhov)
- Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
(Bryant Ly + MNC)
- Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
- Add TCMU support for global block data pool (Xiubo Li + MNC)
and on the bug-fix side:
- Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
failures (Gary Guo + nab)
- Fix iscsi-target hang with explicitly changing per NodeACL
CmdSN number depth with concurrent login driven session
reinstatement. (Gary Guo + nab)
- Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
- Fix target-core/FILEIO zero length handling (Bart Van Assche)
Also, there was an OOPs introduced with the WRITE_VERIFY changes that
I ended up reverting at the last minute, because as not unusual Bart
and I could not agree on the fix in time for -rc1. Since it's specific
to a conformance test, it's been reverted for now.
There is a separate patch in the queue to address the underlying
control CDB write overflow regression in >= v4.3 separate from the
WRITE_VERIFY revert here, that will be pushed post -rc1"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (30 commits)
Revert "target: Fix VERIFY and WRITE VERIFY command parsing"
IB/srpt: Avoid that aborting a command triggers a kernel warning
IB/srpt: Fix abort handling
target/fileio: Fix zero-length READ and WRITE handling
ibmvscsis: Do not send aborted task response
tcmu: fix module removal due to stuck thread
target: Don't force session reset if queue_depth does not change
iscsi-target: Set session_fall_back_to_erl0 when forcing reinstatement
target: Fix compare_and_write_callback handling for non GOOD status
tcmu: Recalculate the tcmu_cmd size to save cmd area memories
tcmu: Add global data block pool support
tcmu: Add dynamic growing data area feature support
target: fixup error message in target_tg_pt_gp_tg_pt_gp_id_store()
target: fixup error message in target_tg_pt_gp_alua_access_type_store()
target/user: PGR Support

Documentation/target: add an example script to configure an iSCSI target
target: Use kmalloc_array() in transport_kmap_data_sg()

This adds initial PGR support for just TCMU, since tcmu doesn't
have the necessary IT_NEXUS info to process PGR in userspace,
so have those commands be processed in kernel.
HA support is not available yet, we will work on it if this patch
is acceptable.

Currently ramdisk and fileio always perform PI verification
before and after backend IO. This approach is not very flexible.
Because some one may want to postpone this work to other layers in
IO stack. For example if we want to test blk_integrity_profile

"Making sure that something like a referral point won't end up as pwd
or root.
The main part is the last commit (fixing mntns_install()); that one
fixes a hard-to-hit race. The fchdir() commit is making fchdir(2) a
bit more robust - it should be impossible to get opened files (even
O_PATH ones) for referral points in the first place, so the existing
checks are OK, but checking the same thing as in chdir(2) is just as
cheap.
The path_init() commit removes a redundant check that shouldn't have
been there in the first place"

Pull more powerpc updates from Michael Ellerman:
"The change to the Linux page table geometry was delayed for more
testing with 16G pages, and there's the new CPU features stuff which
just needed one more polish before going in. Plus a few changes from
Scott which came in a bit late. And then various fixes, mostly minor.
Summary highlights:
- rework the Linux page table geometry to lower memory usage on
64-bit Book3S (IBM chips) using the Hash MMU.
- support for a new device tree binding for discovering CPU features
on future firmwares.
- Freescale updates from Scott:
"Includes a fix for a powerpc/next mm regression on 64e, a fix for
a kernel hang on 64e when using a debugger inside a relocated
kernel, a qman fix, and misc qe improvements."
Thanks to: Christophe Leroy, Gavin Shan, Horia Geantă, LiuHailong,
Nicholas Piggin, Roy Pledge, Scott Wood, Valentin Longchamp"

Some displays require setting AUS mode in the LDCD AUS Mode Control
Register to work with the imxfb driver. Like the value of the Panel
Configuration Register, the AUS mode setting depends on the display
mode.
Allow setting AUS mode from the device tree by adding a boolean
property. Make this property optional to keep the DT ABI stable.
AUS mode can be set only on imx21 and compatible chipsets.

In some cases, nand_do_{read,write}_ops is passed with unaligned
ops->datbuf. Drivers using DMA will be unhappy about unaligned
buffer.
The new struct member, buf_align, represents the minimum alignment
the driver require for the buffer. If the buffer passed from the
upper MTD layer does not have enough alignment, nand_do_*_ops will
use bufpoi.

The comment for ecc.read_page() requires that it should return
"0 if bitflips uncorrectable".
Actually, drivers could return positive values when uncorrectable
bitflips occur. For example, nand_read_page_swecc() is the case.
If ecc.correct() returns -EBADMSG for the first ECC sector, and
a positive value for the second one, nand_read_page_swecc() returns
a positive max_bitflips and increments ecc_stats.failed for the same
page.
The requirement can be relaxed by tweaking nand_do_read_ops().
Move the max_bitflips calculation below the retry.

A lot of NANDs are implementing generic features in a non-generic way,
or are providing advanced auto-detection logic where the NAND ID bytes
meaning changes with the NAND generation.
Providing this vendor specific initialization step will allow us to get
rid of full-id entries in the nand_ids table or all the vendor specific
cases added over the time in the generic NAND ID decoding logic.

There is no reason to expose the NAND manufacturer table. Provide an
helper function to find manufacturers by their id.
We also turn the nand_manufacturers table into a const array, since its
members are not modified after the initial assignment.
Finally, we remove the sentinel manufacturer entry from the manufacturers
table (we already have the array size information given by ARRAY_SIZE()),
and add the nand_manufacturer_name() helper to handle the "Unknown" case
properly.

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.
In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.
After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

Pull hw lockdown support from David Howells:
"Annotation of module parameters that configure hardware resources
including ioports, iomem addresses, irq lines and dma channels.
This allows a future patch to prohibit the use of such module
parameters to prevent that hardware from being abused to gain access
to the running kernel image as part of locking the kernel down under
UEFI secure boot conditions.
Annotations are made by changing:
module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)
to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

Provided an annotation for module parameters that specify hardware
parameters (such as io ports, iomem addresses, irqs, dma channels, fixed
dma buffers and other types).
This will enable such parameters to be locked down in the core parameter
parser for secure boot support.
I've also included annotations as to what sort of hardware configuration
each module is dealing with for future use. Some of these are
straightforward (ioport, iomem, irq, dma), but there are also:
(1) drivers that switch the semantics of a parameter between ioport and
iomem depending on a second parameter,
(2) drivers that appear to reserve a CPU memory buffer at a fixed address,
(3) other parameters, such as bus types and irq selection bitmasks.
For the moment, the hardware configuration type isn't actually stored,
though its validity is checked.

me not catching up as quickly on patch review than anything else.
Overall it seems normal though, a few small changes to the core,
mostly small non-critical fixes here and there as well as driver
updates for new and existing hardware support.
The biggest things are the TI clk driver rework to lay the groundwork
for clkctrl support in the next merge window and the AmLogic
audio/graphics clk support.
Core:
- clk_possible_parents debugfs file so we know which parents a clk
could possibly have
- Fix to make clk rate change notifiers stop on the first failure
instead of continuing
New Drivers:
- Mediatek MT6797 SoCs
- hi655x PMIC clks
- AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
- Allwinner H5 SoCs and PRCM hardware
Updates:
- Nvidia Tegra T210 cleanups and non-critical fixes
- TI OMAP cleanups in preparation for clkctrl support
- trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
- ZTE zx296718 SoC VGA clks
- Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
- IDT VersaClock 5P49V5935 support
- Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3
support"
