Radim Krčmář f9dcf08e20 Revert "kvm: x86: optimize dr6 restore"
This reverts commit 0e0a53c551.

As Christian Ehrhardt noted:

  The most common case is that vcpu->arch.dr6 and the host's %dr6 value
  are not related at all because ->switch_db_regs is zero. To do this
  all correctly, we must handle the case where the guest leaves an arbitrary
  unused value in vcpu->arch.dr6 before disabling breakpoints again.

  However, this means that vcpu->arch.dr6 is not suitable to detect the
  need for a %dr6 clear.

Will Deacon 14fdc2c531 Documentation/security-bugs: Clarify treatment of embargoed information
The Linux kernel security team has been accused of rejecting the idea of
security embargoes. This is incorrect, and could dissuade people from
reporting security issues to us under the false assumption that the
issue would leak prematurely.

Clarify the handling of embargoed information in our process
documentation.

Linus Torvalds cee1352f79 Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar:
 "The biggest change in this cycle is the conclusion of the big
  'simplify RCU to two primary flavors' consolidation work - i.e.
  there's a single RCU flavor for any kernel variant (PREEMPT and
  !PREEMPT):

    - Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
      single flavor similar to RCU-sched in !PREEMPT kernels and into a
      single flavor similar to RCU-preempt (but also waiting on
      preempt-disabled sequences of code) in PREEMPT kernels.

      This branch also includes a refactoring of
      rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.

    - Now that there is only one RCU flavor in any given running kernel,
      the many "rsp" pointers are no longer required, and this cleanup
      series removes them.

    - This branch carries out additional cleanups made possible by the
      RCU flavor consolidation, including inlining now-trivial
      functions, updating comments and definitions, and removing
      now-unneeded rcutorture scenarios.

    - Now that there is only one flavor of RCU in any running kernel,
      there is also only on rcu_data structure per CPU. This means that
      the rcu_dynticks structure can be merged into the rcu_data
      structure, a task taken on by this branch. This branch also
      contains a -rt-related fix from Mike Galbraith.

  There were also other updates:

    - Documentation updates, including some good-eye catches from Joel
      Fernandes.

    - SRCU updates, most notably changes enabling call_srcu() to be
      invoked very early in the boot sequence.

    - Torture-test updates, including some preliminary work towards
      making rcutorture better able to find problems that result in
      insufficient grace-period forward progress.

    - Initial changes to RCU to better promote forward progress of grace
      periods, including fixing a bug found by Marius Hillenbrand and
      David Woodhouse, with the fix suggested by Peter Zijlstra"

Linus Torvalds e2b623fbe6 s390 updates for the 4.20 merge window
- Improved access control for the zcrypt driver, multiple device nodes
    can now be created with different access control lists
 
  - Extend the pkey API to provide random protected keys, this is useful
    for encrypted swap device with ephemeral protected keys
 
  - Add support for virtually mapped kernel stacks
 
  - Rework the early boot code, this moves the memory detection into the
    boot code that runs prior to decompression.
 
  - Add KASAN support
 
  - Bug fixes and cleanups

- Fix ACPICA issues related to the handling of module-level AML
    and make the ACPI initialization code parse ECDT before loading
    the definition block tables (Erik Schmauss).
 
  - Update ACPICA to upstream revision 20181003 including fixes
    related to the ill-defined "generic serial bus" and the handling

    related to the handling of I2C controllers in the ACPI LPSS driver
    for Intel SoCs (Hans de Goede).

    devices as platform devices with I2C resources to avoid device
    enumeration problems on boards with Dollar Cove or Whiskey Cove
    Intel PMICs (Hans de Goede).
 
  - Prevent ACPICA from using ktime_get() during early resume from
    system-wide suspend before resuming the timekeeping which generally
    is unsafe and triggers a warning from the timekeeping code (Bart
    Van Assche).
 
  - Add low-level real time clock support to the ACPI Time and Aalarm
    Device (TAD) driver (Rafael Wysocki).
 
  - Fix the ACPI SBS driver to avoid GPE storms on MacBook Pro and

    into account properly in some cases (Rafael Wysocki).
 
  - Add support for retrieving guaranteed performance information
    to the ACPI CPPC library and make the intel_pstate driver use
    it to expose the CPU base frequency via sysfs on systems with
    the hardware-managed P-states (HWP) feature enabled (Srinivas
    Pandruvada).

Nathan Chancellor 6eb3578443 mfd: cros_ec: Avoid unneeded internal declaration warning
Clang warns:

drivers/mfd/cros_ec_dev.c:509:40: warning: variable 'cros_ec_id' is not
needed and will not be emitted [-Wunneeded-internal-declaration]
static const struct platform_device_id cros_ec_id[] = {
                                       ^
1 warning generated.

Avoid this warning by adding it to the cros_ec_dev_driver definition
under the id_table member like all other platform drivers.

Pavel Machek 697894b9b8 mfd: ti-lmu: Use of_device_get_match_data() helper
Replace of_match_device() with of_device_get_match_data(), which
slightly decreases lines of code and allows to move the DT table
next to the I2C table.

Pavel Machek 7891d37509 mfd: ti-lmu: Use managed resource for everything
This replaces all remaining unmanaged resources with device
managed ones, so that the remove function is no longer needed.
This makes the code slightly shorter and fixes two problems:

 1. The hardware is disabled after the child devices have
    been removed. Previously there was a potential race
    condition.
 2. The hardware is disabled when mfd_add_devices fails
    during probe.

Marek Szyprowski c1aaaa1cb7 mfd: max8997: Disable interrupt handling for suspend/resume cycle
Disable IRQs during suspend/resume cycle to ensure handling of wakeup
interrupts (i.e. RTC wake alarm) after max8997_resume(). This way it can
be properly handled when I2C bus is finally available. This pattern is
also used in other MAX PMIC MFD drivers.

Marek Szyprowski efddff27c8 mfd: max8997: Enale irq-wakeup unconditionally
IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.

Andy Shevchenko 1e984d6d3b MAINTAINERS: Add myself as designated reviewer of Intel MFD PMIC
There are few Intel MFD PMIC device drivers which I would like
to review.

Note, Intel MSIC is old system controller that based mostly on PMIC
integrated in it. Thus, I included it as well.

Andy Shevchenko 9f8ddee1da mfd: intel_soc_pmic_bxtwc: Chain power button IRQs as well
Power button IRQ actually has a second level of interrupts to
distinguish between UI and POWER buttons. Moreover, current
implementation looks awkward in approach to handle second level IRQs by
first level related IRQ chip.

To address above issues, split power button IRQ to be chained as well.
