git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek:
- Different vendors have a different expectation about a console
quietness. Make it configurable to reduce bike-shedding about the
upstream default
- Decide about the message visibility when the message is stored. It
avoids races caused by a delayed console handling
- Always store printk() messages into the per-CPU buffers again in NMI.
The only exception is when flushing trace log in panic(). There the
risk of loosing messages is worth an eventual reordering
- Handle invalid %pO printf modifiers correctly
- Better handle %p printf modifier tests before crng is initialized
- Some clean up

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"A bunch of good stuff in here. Worth noting is that we've pulled in
the x86/mm branch from -tip so that we can make use of the core
ioremap changes which allow us to put down huge mappings in the
vmalloc area without screwing up the TLB. Much of the positive
diffstat is because of the rseq selftest for arm64.
Summary:
- Wire up support for qspinlock, replacing our trusty ticket lock
code
- Add an IPI to flush_icache_range() to ensure that stale
instructions fetched into the pipeline are discarded along with the
I-cache lines
- Support for the GCC "stackleak" plugin
- Support for restartable sequences, plus an arm64 port for the
selftest
- Kexec/kdump support on systems booting with ACPI
- Rewrite of our syscall entry code in C, which allows us to zero the
GPRs on entry from userspace
- Support for chained PMU counters, allowing 64-bit event counters to
be constructed on current CPUs
- Ensure scheduler topology information is kept up-to-date with CPU
hotplug events
- Re-enable support for huge vmalloc/IO mappings now that the core
code has the correct hooks to use break-before-make sequences
- Miscellaneous, non-critical fixes and cleanups"

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"These revert two ACPICA commits that are not needed any more, rework
the property graphs support in ACPI to be more aligned with the
analogous DT code, add some new quirks and remove one that isn't
needed any more, add a special platform driver to enumerate multiple
I2C devices hooked up to the same device object in the ACPI tables and
update the battery and button drivers.
Specifics:
- Revert two ACPICA commits that are not needed any more (Erik
Schmauss).
- Rework property graph support in the ACPI device properties
framework to make it behave more like the analogous DT code and
update the documentation of it (Sakari Ailus).
- Change the default ACPI device status after initialization to
ACPI_STA_DEFAULT instead of 0 (Hans de Goede).
- Add a special platform driver for enumerating multiple I2C devices
hooked up to the same object in the ACPI tables (Hans de Goede).
- Fix the ACPI battery driver to avoid reporting full capacity on

Pull power management updates from Rafael Wysocki:
"These add a new framework for CPU idle time injection, to be used by
all of the idle injection code in the kernel in the future, fix some
issues and add a number of relatively small extensions in multiple
places.

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).

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).

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"

Pull regulator updates from Mark Brown:
"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.

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"

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
reworking of the deferred transaction operations handling code, the
removal of the long defunct barrier/nobarrier mount options, and the
addition of a few more online repair functions.
Summary:
- 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 btrfs updates from David Sterba:
"Mostly fixes and cleanups, nothing big, though the notable thing is
the inserted/deleted lines delta -1124.
User visible changes:
- allow defrag on opened read-only files that have rw permissions;
similar to what dedupe will allow on such files
Core changes:
- tree checker improvements, reported by fuzzing:
* more checks for: block group items, essential trees
* chunk type validation
* mount time cross-checks that physical and logical chunks match
* switch more error codes to EUCLEAN aka EFSCORRUPTED
Fixes:
- fsync corner case fixes
- fix send failure when root has deleted files still open
- send, fix incorrect file layout after hole punching beyond eof
- fix races between mount and deice scan ioctl, found by fuzzing
- fix deadlock when delayed iput is called from writeback on the same
inode; rare but has been observed in practice, also removes code
- fix pinned byte accounting, using the right percpu helpers; this
should avoid some write IO inefficiency during low space conditions
- don't remove block group that still has pinned bytes
- reset on-disk device stats value after replace, otherwise this
would report stale values for the new device
Cleanups:
- time64_t/timespec64 cleanups
- remove remaining dead code in scrub handling NOCOW extents after
disabling it in previous cycle
- simplify fsync regarding ordered extents logic and remove all the
related code
- remove redundant arguments in order to reduce stack space

Pull MIPS updates from Paul Burton:
"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 x86 PTI updates from Thomas Gleixner:
"The Speck brigade sadly provides yet another large set of patches
destroying the perfomance which we carefully built and preserved
- PTI support for 32bit PAE. The missing counter part to the 64bit
PTI code implemented by Joerg.
- A set of fixes for the Global Bit mechanics for non PCID CPUs which
were setting the Global Bit too widely and therefore possibly
exposing interesting memory needlessly.
- Protection against userspace-userspace SpectreRSB
- Support for the upcoming Enhanced IBRS mode, which is preferred
over IBRS. Unfortunately we dont know the performance impact of
this, but it's expected to be less horrible than the IBRS

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"
