Power management updates for 4.19-rc1
- Add a new framework for CPU idle time injection (Daniel Lezcano).
- Add AVS support to the armada-37xx cpufreq driver (Gregory CLEMENT).
- Add support for current CPU frequency reporting to the ACPI CPPC
cpufreq driver (George Cherian).
- Rework the cooling device registration in the imx6q/thermal
driver (Bastian Stender).
- Make the pcc-cpufreq driver refuse to work with dynamic
scaling governors on systems with many CPUs to avoid
scalability issues with it (Rafael Wysocki).
- Fix the intel_pstate driver to report different maximum CPU
frequencies on systems where they really are different and to
ignore the turbo active ratio if hardware-managend P-states (HWP)
are in use; make it use the match_string() helper (Xie Yisheng,
Srinivas Pandruvada).
- Fix a minor deferred probe issue in the qcom-kryo cpufreq
driver (Niklas Cassel).
- Add a tracepoint for the tracking of frequency limits changes
(from Andriod) to the cpufreq core (Ruchi Kandoi).
- Fix a circular lock dependency between CPU hotplug and sysfs
locking in the cpufreq core reported by lockdep (Waiman Long).
- Avoid excessive error reports on driver registration failures
in the ARM cpuidle driver (Sudeep Holla).
- Add a new device links flag to the driver core to make links go
away automatically on supplier driver removal (Vivek Gautam).
- Eliminate potential race condition between system-wide power
management transitions and system shutdown (Pingfan Liu).
- Add a quirk to save NVS memory on system suspend for the ASUS
1025C laptop (Willy Tarreau).
- Make more systems use suspend-to-idle (instead of ACPI S3) by
default (Tristian Celestin).
- Get rid of stack VLA usage in the low-level hibernation code on
64-bit x86 (Kees Cook).
- Fix error handling in the hibernation core and mark an expected
fall-through switch in it (Chengguang Xu, Gustavo Silva).
- Extend the generic power domains (genpd) framework to support
attaching a device to a power domain by name (Ulf Hansson).
- Fix device reference counting and user limits initialization in
the devfreq core (Arvind Yadav, Matthias Kaehlcke).
- Fix a few issues in the rk3399_dmc devfreq driver and improve its
documentation (Enric Balletbo i Serra, Lin Huang, Nick Milner).
- Drop a redundant error message from the exynos-ppmu devfreq driver
(Markus Elfring).

Pull LED updates from Jacek Anaszewski:
"LED triggers improvements make the biggest part of this pull request.
The most striking ones, that allowed for nice cleanups in the triggers
are:
- centralized handling of creation and removal of trigger sysfs
attributes via attribute group
- addition of module_led_trigger() helper
The other things that need to be mentioned:
New features and improvements to existing LED class drivers:
- lt3593: add DT support, switch to gpiod interface
- lm3692x: support LED sync configuration, change OF calls to fwnode
calls
- apu: modify PC Engines apu/apu2 driver to support apu3
Change in the drivers/net/can/led.c:
- mark led trigger as broken since it's in the way for the further
cleanups. It implements a subset of the netdev trigger and an Ack
is needed from someone who can actually test and confirm that the
netdev trigger works for can devices"

This is the bulk of pin control changes for v4.19:
Core changes:
- Augment pinctrl_generic_add_group() and pinmux_generic_add_function()
to return the selector for the added group/function to the caller
and augment (hopefully) all drivers to handle this.
New subdrivers:
- Qualcomm PM8998 and PM8005 are supported in the SPMI pin
control and GPIO driver.
- Intel Ice Lake PCH (platform controller hub) support.
- NXP (ex Freescale) i.MX8MQ support.
- Berlin AS370 support.
Improvements to drivers:
- Support interrupts on the Ocelot pin controller.
- Add SPI pins to the Uniphier driver.
- Define a GPIO compatible per SoC in the Tegra driver.
- Push Tegra initialization down in the initlevels.
- Support external wakeup interrupts on the Exynos.
- Add generic clocks pins to the meson driver.
- Add USB and HSCIF pins for some Renesas PFC chips.
- Suspend/resume support in the armada-37xx.
- Interrupt support for the Actions Semiconductor S900 also
known as "owl".
- Correct the pin ordering in Cedarfork.
- Debugfs output for INTF in the mcp23s08 driver
- Avoid divisions in context save/restore in pinctrl-single.
The rest is minor bug fixes or cleanups.

regulator: Changes for v4.19
The biggest set of changes in here is the addition of the Qualcomm RPMH
driver. As well as the regualtor driver itself being quite large due to
the usual involved Qualcomm regulator stuff there's also some code
shared with the arm-soc tree, a bus driver required to communicate with
the hardware that actually winds up being much larger than the regulator
driver itself and a LLCC driver that was part of the same signed tag
used with the arm-soc tree.
Other than that it's a fairly standard and quiet release, highlights
include:
- Addition of device links from regulator consumers to their
regulators, helping the core avoid dependency issues during suspend.
- Support for the entertainingly innovative suspend implementation in
the BD9571MWV.
- Support for switch regulators on the PFUZE100, this required two goes
due to backwards compatibility issues with old DTs that were
discovered.
- Support for Freescale PFUZE3001 and SocioNext UniPhier.
- The aforementioned Qualcomm RPMH driver together with the driver
changes required to support it.

Merge branch 'l1tf-final' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Merge L1 Terminal Fault fixes from Thomas Gleixner:
"L1TF, aka L1 Terminal Fault, is yet another speculative hardware
engineering trainwreck. It's a hardware vulnerability which allows
unprivileged speculative access to data which is available in the
Level 1 Data Cache when the page table entry controlling the virtual
address, which is used for the access, has the Present bit cleared or
other reserved bits set.
If an instruction accesses a virtual address for which the relevant
page table entry (PTE) has the Present bit cleared or other reserved
bits set, then speculative execution ignores the invalid PTE and loads
the referenced data if it is present in the Level 1 Data Cache, as if
the page referenced by the address bits in the PTE was still present
and accessible.
While this is a purely speculative mechanism and the instruction will
raise a page fault when it is retired eventually, the pure act of
loading the data and making it available to other speculative
instructions opens up the opportunity for side channel attacks to
unprivileged malicious code, similar to the Meltdown attack.
While Meltdown breaks the user space to kernel space protection, L1TF
allows to attack any physical memory address in the system and the
attack works across all protection domains. It allows an attack of SGX
and also works from inside virtual machines because the speculation
bypasses the extended page table (EPT) protection mechanism.
The assoicated CVEs are: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646
The mitigations provided by this pull request include:
- Host side protection by inverting the upper address bits of a non
present page table entry so the entry points to uncacheable memory.
- Hypervisor protection by flushing L1 Data Cache on VMENTER.
- SMT (HyperThreading) control knobs, which allow to 'turn off' SMT
by offlining the sibling CPU threads. The knobs are available on
the kernel command line and at runtime via sysfs
- Control knobs for the hypervisor mitigation, related to L1D flush
and SMT control. The knobs are available on the kernel command line
and at runtime via sysfs
- Extensive documentation about L1TF including various degrees of
mitigations.
Thanks to all people who have contributed to this in various ways -
patches, review, testing, backporting - and the fruitful, sometimes
heated, but at the end constructive discussions.
There is work in progress to provide other forms of mitigations, which
might be less horrible performance wise for a particular kind of
workloads, but this is not yet ready for consumption due to their
complexity and limitations"

Changes for 4.19:
- Use extent maps to track pagecache page status instead of bufferhead
state.
- Refactor pagecache read and write paths to use the new iomap library
functions, which enable us to drop the old bufferhead code for
pagesize == blocksize filesystems.
- Set up parallel per-block-per-page metadata to track subpage
information that was tracked by buffer heads, which enables us to drop
the old bufferhead code for pagesize > blocksize filesystems.
- Tie a deferred ops control structure to a transaction so that we can
take advantage of an upper-level dfops without having to plumb pointer
passing through the code.
- Refactor the deferred ops code to track deferred ops as part of the
transaction structure (instead of as a separate data structure) so
that we can simplify the scoping rules around defer_ops.
- Refactor twisty delwri buffer submission code to avoid deadlocks.
- Shorten and fix indenting problems in the scrub code.
- Detect obviously bad summary counts at mount and fix them.
- Directly associate deferred ops control structure with a transaction
so that callers no longer have to manage it themselves.
- Remove a couple of IRIX-era inode macros.
- Remove the long-deprecated 'barrier' and 'nobarrier' mount options.
- Clean up the inode fork structure a bit.
- Check for bad fs summary counter values in the superblock.
- Reduce COW fork lookups during writeback.
- Refactor the deferred ops control structures into the transaction
structure, thereby eliminating the need for transaction users to
handle the deferred ops as a separate data structure.
- Add the ability to repair AG headers online.
- Fix a crash due to insufficient return value checking.
- Various fixes and cleanups.

Pull xfs updates from Darrick Wong:
"This is the second part of the XFS changes for 4.19.
The biggest changes are the removal of buffer heads frm XFS, a massive

addition of a few more online repair functions.

bufferhead state.
- Refactor pagecache read and write paths to use the new iomap
library functions, which enable us to drop the old bufferhead code

Here are the main MIPS changes for 4.19.
An overview of the general architecture changes:
- Massive DMA ops refactoring from Christoph Hellwig (huzzah for
deleting crufty code!).
- We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes & corresponding
regsets to expose DSP ASE & floating point mode state respectively,
both for live debugging & core dumps.
- We better optimize our code by hard-coding cpu_has_* macros at
compile time where their values are known due to the ISA revision
that the kernel build is targeting.
- The EJTAG exception handler now better handles SMP systems, where it
was previously possible for CPUs to clobber a register value saved
by another CPU.
- Our implementation of memset() gained a couple of fixes for MIPSr6
systems to return correct values in some cases where stores fault.
- We now implement ioremap_wc() using the uncached-accelerated cache
coherency attribute where supported, which is detected during boot,
and fall back to plain uncached access where necessary. The
MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
ioremap_cacheable_cow() are removed.
- The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
systems by reworking the way we ensure remote CPUs that may be
running threads within the affected process switch mode.
- Systems using the MIPS Coherence Manager will now set the
MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
maintenance overhead when flushing the icache.
- A few fixes were made for building with clang/LLVM, which
now sucessfully builds kernels for many of our platforms.
- Miscellaneous cleanups all over.
And some platform-specific changes:
- ar7 gained stubs for a few clock API functions to fix build failures
for some drivers.
- ath79 gained support for a few new SoCs, a few fixes & better
gpio-keys support.
- Ci20 now exposes its SPI bus using the spi-gpio driver.
- The generic platform can now auto-detect a suitable value for
PHYS_OFFSET based upon the memory map described by the device tree,
allowing us to avoid wasting memory on page book-keeping for systems
where RAM starts at a non-zero physical address.
- Ingenic systems using the jz4740 platform code now link their
vmlinuz higher to allow for kernels of a realistic size.
- Loongson32 now builds the kernel targeting MIPSr1 rather than MIPSr2
to avoid CPU errata.
- Loongson64 gains a couple of fixes, a workaround for a write
buffering issue & support for the Loongson 3A R3.1 CPU.
- Malta now uses the piix4-poweroff driver to handle powering down.
- Microsemi Ocelot gained support for its SPI bus & NOR flash, its
second MDIO bus and can now be supported by a FIT/.itb image.
- Octeon saw a bunch of header cleanups which remove a lot of
duplicate or unused code.

Pull s390 updates from Heiko Carstens:
"Since Martin is on vacation you get the s390 pull request from me:
- Host large page support for KVM guests. As the patches have large
impact on arch/s390/mm/ this series goes out via both the KVM and
the s390 tree.
- Add an option for no compression to the "Kernel compression mode"
menu, this will come in handy with the rework of the early boot
code.
- A large rework of the early boot code that will make life easier
for KASAN and KASLR. With the rework the bootable uncompressed
image is not generated anymore, only the bzImage is available. For
debuggung purposes the new "no compression" option is used.
- Re-enable the gcc plugins as the issue with the latent entropy
plugin is solved with the early boot code rework.
- More spectre relates changes:
+ Detect the etoken facility and remove expolines automatically.
+ Add expolines to a few more indirect branches.
- A rewrite of the common I/O layer trace points to make them
consumable by 'perf stat'.
- Add support for format-3 PCI function measurement blocks.
- Changes for the zcrypt driver:
+ Add attributes to indicate the load of cards and queues.
+ Restructure some code for the upcoming AP device support in KVM.
- Build flags improvements in various Makefiles.
- A few fixes for the kdump support.
- A couple of patches for gcc 8 compile warning cleanup.
- Cleanup s390 specific proc handlers.
- Add s390 support to the restartable sequence self tests.
- Some PTR_RET vs PTR_ERR_OR_ZERO cleanup.

Pull x86 cache QoS (RDT/CAR) updates from Thomas Gleixner: "Add support for pseudo-locked cache regions. Cache Allocation Technology (CAT) allows on certain CPUs to isolate a region of cache and 'lock' it. Cache pseudo-locking builds on the fact that a CPU can still read and write data pre-allocated outside its current allocated area on cache hit. With cache pseudo-locking data can be preloaded into a reserved portion of cache that no application can fill, and from that point on will only serve cache hits. The cache pseudo-locked memory is made accessible to user space where an application can map it into its virtual address space and thus have a region of memory with reduced average read latency. The locking is not perfect and gets totally screwed by WBINDV and similar mechanisms, but it provides a reasonable enhancement for certain types of latency sensitive applications. The implementation extends the current CAT mechanism and provides a generally useful exclusive CAT mode on which it builds the extra pseude-locked regions" * 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (45 commits) x86/intel_rdt: Disable PMU access x86/intel_rdt: Fix possible circular lock dependency x86/intel_rdt: Make CPU information accessible for pseudo-locked regions x86/intel_rdt: Support restoration of subset of permissions x86/intel_rdt: Fix cleanup of plr structure on error x86/intel_rdt: Move pseudo_lock_region_clear() x86/intel_rdt: Limit C-states dynamically when pseudo-locking active x86/intel_rdt: Support L3 cache performance event of Broadwell x86/intel_rdt: More precise L2 hit/miss measurements x86/intel_rdt: Create character device exposing pseudo-locked region x86/intel_rdt: Create debugfs files for pseudo-locking testing x86/intel_rdt: Create resctrl debug area x86/intel_rdt: Ensure RDT cleanup on exit x86/intel_rdt: Resctrl files reflect pseudo-locked information x86/intel_rdt: Support creation/removal of pseudo-locked region x86/intel_rdt: Pseudo-lock region creation/removal core x86/intel_rdt: Discover supported platforms via prefetch disable bits x86/intel_rdt: Add utilities to test pseudo-locked region possibility x86/intel_rdt: Split resource group removal in two x86/intel_rdt: Enable entering of pseudo-locksetup mode ... |

Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Thomas Gleixner:
"A large update to RCU:
Preparatory work for consolidating the RCU flavors:
- Introduce grace-period sequence numbers to the RCU-bh, RCU-preempt,
and RCU-sched flavors, replacing the old ->gpnum and ->completed
pair of fields.
This change allows lockless code to obtain the complete
grace-period state with a single READ_ONCE(), which is needed to
maintain tolerable lock contention during the upcoming
consolidation of the three RCU flavors.
Note that grace-period sequence numbers are already used by
rcu_barrier(), expedited RCU grace periods, and SRCU, and are thus
already heavily used and well-tested. Joel Fernandes contributed a
number of excellent fixes and improvements.
- Clean up some grace-period-reporting loose ends, including
improving the handling of quiescent states from offline CPUs and
fixing some false-positive WARN_ON_ONCE() invocations.
(Strictly speaking, the WARN_ON_ONCE() invocations were quite
correct, but their invariants were (harmlessly) violated by the
earlier sloppy handling of quiescent states from offline CPUs.)
In addition, improve grace-period forward-progress guarantees so as
to allow removal of fail-safe checks that required otherwise
needless lock acquisitions. Finally, add more diagnostics to help
debug the upcoming consolidation of the RCU-bh, RCU-preempt, and
RCU-sched flavors.
The rest:
- SRCU updates
- Updates to rcutorture and associated scripting.
- The usual pile of miscellaneous fixes"

PM / reboot: Eliminate race between reboot and suspend
At present, "systemctl suspend" and "shutdown" can run in parrallel. A system can suspend after devices_shutdown(), and resume. Then the shutdown task goes on to power off. This causes many devices are not really shut off. Hence replacing reboot_mutex with system_transition_mutex (renamed from pm_mutex) to achieve the exclusion. The renaming of pm_mutex as system_transition_mutex can be better to reflect the purpose of the mutex.

KVM: VMX: Tell the nested hypervisor to skip L1D flush on vmentry
When nested virtualization is in use, VMENTER operations from the nested hypervisor into the nested guest will always be processed by the bare metal hypervisor, and KVM's "conditional cache flushes" mode in particular does a flush on nested vmentry. Therefore, include the "skip L1D flush on vmentry" bit in KVM's suggested ARCH_CAPABILITIES setting. Add the relevant Documentation.

block: make iolatency avg_lat exponentially decay
Currently, avg_lat is calculated by accumulating the mean of every window in a long running cumulative average. As time goes on, the metric becomes less and less useful due to the accumulated history. This patch reuses the same calculation done in load averages to make the avg_lat metric more lively. Unlike load averages, the avg only advances when a window elapses (due to an io). Idle periods extend the most recent window. Bucketing is used to limit the history of avg_lat by binding it to the window size. So, the window range for 1/exp (decay rate) is [1 min, 2.5 min) when windows elapse immediately. The current sample window size is exposed in the debug info to enable calculation of the window range.
