Linus Torvalds fbe173e3ff RTC for 4.17
Subsystem:
  - Add tracepoints
  - Rework of the RTC/nvmem API to allow drivers to discard struct nvmem_config
    after registration

    modifying the supported range.
  - Multiple rtc_time64_to_tm fixes
  - Handle time_t overflow on 32 bit platforms in the core instead of letting
    drivers do crazy things.
  - remove rtc_control API
 
 New driver:
  - Intersil ISL12026
 
 Drivers:
  - Drivers exposing the RTC non volatile memory have been converted to use nvmem

Pull integrity updates from James Morris:
 "A mixture of bug fixes, code cleanup, and continues to close
  IMA-measurement, IMA-appraisal, and IMA-audit gaps.

  Also note the addition of a new cred_getsecid LSM hook by Matthew
  Garrett:

     For IMA purposes, we want to be able to obtain the prepared secid
     in the bprm structure before the credentials are committed. Add a
     cred_getsecid hook that makes this possible.

  which is used by a new CREDS_CHECK target in IMA:

     In ima_bprm_check(), check with both the existing process
     credentials and the credentials that will be committed when the new
     process is started. This will not change behaviour unless the
     system policy is extended to include CREDS_CHECK targets -
     BPRM_CHECK will continue to check the same credentials that it did
     previously"

Linus Torvalds 274c0e74e5 f2fs-for-4.17-rc1
In this round, we've mainly focused on performance tuning and critical bug fixes
 occurred in low-end devices. Sheng Yong introduced lost_found feature to keep
 missing files during recovery instead of thrashing them. We're preparing coming
 fsverity implementation. And, we've got more features to communicate with users
 for better performance. In low-end devices, some memory-related issues were
 fixed, and subtle race condtions and corner cases were addressed as well.
 
 Enhancement:
  - large nat bitmaps for more free node ids
  - add three block allocation policies to pass down write hints given by user
  - expose extension list to user and introduce hot file extension
  - tune small devices seamlessly for low-end devices
  - set readdir_ra by default
  - give more resources under gc_urgent mode regarding to discard and cleaning
  - introduce fsync_mode to enforce posix or not
  - nowait aio support
  - add lost_found feature to keep dangling inodes
  - reserve bits for future fsverity feature
  - add test_dummy_encryption for FBE
 
 Bug fix:
  - don't use highmem for dentry pages
  - align memory boundary for bitops
  - truncate preallocated blocks in write errors
  - guarantee i_times on fsync call
  - clear CP_TRIMMED_FLAG correctly
  - prevent node chain loop during recovery
  - avoid data race between atomic write and background cleaning
  - avoid unnecessary selinux violation warnings on resgid option
  - GFP_NOFS to avoid deadlock in quota and read paths
  - fix f2fs_skip_inode_update to allow i_size recovery
 
 In addition to them, there are several minor bug fixes and clean-ups.

Linus Torvalds df34df483a Staging/IIO patches for 4.17-rc1
Here is the big set of Staging/IIO driver patches for 4.17-rc1.
 
 It is a lot, over 500 changes, but not huge by previous kernel release
 standards.  We deleted more lines than we added again (27k added vs. 91k
 remvoed), thanks to finally being able to delete the IRDA drivers and
 networking code.
 
 We also deleted the ccree crypto driver, but that's coming back in
 through the crypto tree to you, in a much cleaned-up form.
 
 Added this round is at lot of "mt7621" device support, which is for an
 embedded device that Neil Brown cares about, and of course a handful of
 new IIO drivers as well.
 
 And finally, the fsl-mc core code moved out of the staging tree to the
 "real" part of the kernel, which is nice to see happen as well.
 
 Full details are in the shortlog, which has all of the tiny cleanup
 patches described.

 staging directory into the "real" part of the kernel, as well as new
 infrastructure being added to be able to handle the different types of
 "roles" that typeC requires.
 
 There is also the normal huge set of USB gadget controller and driver
 updates, along with XHCI changes, and a raft of other tiny fixes all
 over the USB tree.  And the PHY driver updates are merged in here as
 well as they interacted with the USB drivers in some places.
 
 All of these have been in linux-next for a while with no reported
 issues.

Pull irq updates from Thomas Gleixner:
 "The usual pile of boring changes:

   - Consolidate tasklet functions to share code instead of duplicating
     it

   - The first step for making the low level entry handler management on
     multi-platform kernels generic

   - A new sysfs file which allows to retrieve the wakeup state of
     interrupts.

   - Ensure that the interrupt thread follows the effective affinity and
     not the programmed affinity to avoid cross core wakeups.

   - Two new interrupt controller drivers (Microsemi Ocelot and Qualcomm
     PDC)

   - Fix the wakeup path clock handling for Reneasas interrupt chips.

   - Rework the boot time register reset for ARM GIC-V2/3

   - Better suspend/resume support for ARM GIV-V3/ITS

Linus Torvalds cc5ada7ca3 Mostly small changes, as usual.
This does add an IPMI BMC server-side driver, to allow a Linux
 system to act as an IPMI controller.  That's the biggest change,
 but it is just a new driver that is fairly narrow in use.
 
 The other largish change is removing ACPI SPMI probe support,
 which should have never really been there in the beginning.

Matthew Garrett d906c10d8a IMA: Support using new creds in appraisal policy
The existing BPRM_CHECK functionality in IMA validates against the
credentials of the existing process, not any new credentials that the
child process may transition to. Add an additional CREDS_CHECK target
and refactor IMA to pass the appropriate creds structure. In
ima_bprm_check(), check with both the existing process credentials and
the credentials that will be committed when the new process is started.
This will not change behaviour unless the system policy is extended to
include CREDS_CHECK targets - BPRM_CHECK will continue to check the same
credentials that it did previously.

After this patch, an IMA policy rule along the lines of:

measure func=CREDS_CHECK subj_type=unconfined_t

will trigger if a process is executed and runs as unconfined_t, ignoring
the context of the parent process. This is in contrast to:

measure func=BPRM_CHECK subj_type=unconfined_t

which will trigger if the process that calls exec() is already executing
in unconfined_t, ignoring the context that the child process executes
into.

Heikki Krogerus fde0aa6c17 usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.

With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.

For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.

Richard Leitner 1cbd53c8cd usb: core: introduce per-port over-current counters
For some userspace applications information on the number of
over-current conditions at specific USB hub ports is relevant.

In our case we have a series of USB hardware (using the cp210x driver)
which communicates using a proprietary protocol. These devices sometimes
trigger an over-current situation on some hubs. In case of such an
over-current situation the USB devices offer an interface for reducing
the max used power. As these conditions are quite rare and imply
performance reductions of the device we don't want to reduce the max
power always.

Therefore give user-space applications the possibility to react
adequately by introducing an over_current_counter in the usb port struct
which is exported via sysfs.

Adrian Hunter ad44837882 scsi: ufs: Add support for Auto-Hibernate Idle Timer
UFS host controllers may support an autonomous power management feature
called the Auto-Hibernate Idle Timer. The timer is set to the number of
microseconds of idle time before the UFS host controller will autonomously
put the link into Hibernate state. That will save power at the expense of
increased latency. Any access to the host controller interface registers
will automatically put the link out of Hibernate state. So once configured,
the feature is transparent to the driver.

Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to
choose between power efficiency or lower latency. Set a default value of
150 ms.

Introduce a driver for the ACPI Time and Alarm Device (TAD) based on
Section 9.18 of ACPI 6.2.

This driver only supports the system wakeup capabilities of the TAD
which are mandatory.  Support for the RTC capabilities of the TAD
will be added to it in the future.

This driver is entirely sysfs-based.  It provides attributes (under
the TAD platform device) to allow user space to manage the AC and DC
wakeup timers of the TAD: set and read their values, set and check
their expire timer wake policies, check and clear their status and
check the capabilities of the TAD reported by AML.  The DC timer
attributes are only present if the TAD supports a separate DC alarm
timer.

The wakeup events handling and power management of the TAD is
expected to be taken care of by the ACPI PM domain attached to its
platform device.

This change introduces an 'external mode' for GPIO-based FSI masters,
allowing the clock and data lines to be driven by an external source.
For example, external mode is selected by a user when an external debug
device is attached to the FSI pins.

To do this, we need to set specific states for the trans, mux and enable
GPIOs, and prevent access to clk & data from the FSI core code (by
returning EBUSY).

External mode is controlled by a sysfs attribute, so add the relevant
information to Documentation/ABI/

Mika Westerberg 9aaa3b8b4c thunderbolt: Add support for preboot ACL
Preboot ACL is a mechanism that allows connecting Thunderbolt devices
boot time in more secure way than the legacy Thunderbolt boot support.
As with the legacy boot option, this also needs to be enabled from the
BIOS before booting is allowed. Difference to the legacy mode is that
the userspace software explicitly adds device UUIDs by sending a special
message to the ICM firmware. Only the devices listed in the boot ACL are
connected automatically during the boot. This works in both "user" and
"secure" security levels.

We implement this in Linux by exposing a new sysfs attribute (boot_acl)
below each Thunderbolt domain. The userspace software can then update
the full list as needed.

OEM-specific BIOS configurations. This information is interesting for
user-space as if the device isn't in SW ACL, it may create a friction in
the user experience where the device is automatically authorized if it's
connected on boot but requires an explicit user action if connected
after OS is up. User-space can use this information to suggest adding
the device to SW ACL for auto-authorization on later connections.

Alexandre Belloni ac75779b72 rtc: nvmem: allow registering the nvmem device before the rtc
Switch the parent of the nvmem device to the parent of the rtc device so it
can be registered before the RTC.

This is a small change in the ABI as the nvmem moves out of the
/sys/class/rtc/rtcX folder to be under the parent device folder (that is
where the previous nvram files where registered).

However, it is still available under its correct location,
/sys/bus/nvmem/devices which is the one that should be used by userspace
applications.

The other benefit is that the nvmem device can stay registered even if the
rtc registration fails. Or it is possible to not register the rtc if the
nvmem registration failed.

Finally, it makes a lot of sense for devices that actually have different
i2c or spi addresses for the RTC and the EEPROM. That is basically how it
would end up when using MFD or even completely separate devices.
