Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of Thunderbolt and USB changes for 6.0-rc1.
Lots of little things here, nothing major, just constant development
on some new hardware support and cleanups of older drivers. Highlights
are:
- lots of typec changes and improvements for new hardware
- new gadget controller driver
- thunderbolt support for new hardware
- the normal set of new usb-serial device ids and cleanups
- loads of dwc3 controller fixes and improvements
- mtu3 driver updates
- testusb fixes for longtime issues (not many people use this tool it
seems.)
- minor driver fixes and improvements over the USB tree
- chromeos platform driver changes were added and then reverted as
they depened on some typec changes, but the cross-tree merges
caused problems so they will come back later through the platform
tree.
All of these have been in linux-next for a while now with no reported
issues"

git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"This brings some long awaited changes, the send protocol bump,
otherwise lots of small improvements and fixes. The main core part is
reworking bio handling, cleaning up the submission and endio and
improving error handling.
There are some changes outside of btrfs adding helpers or updating
API, listed at the end of the changelog.
Features:
- sysfs:
- export chunk size, in debug mode add tunable for setting its size
- show zoned among features (was only in debug mode)
- show commit stats (number, last/max/total duration)
- send protocol updated to 2
- new commands:
- ability write larger data chunks than 64K
- send raw compressed extents (uses the encoded data ioctls),
ie. no decompression on send side, no compression needed on
receive side if supported
- send 'otime' (inode creation time) among other timestamps
- send file attributes (a.k.a file flags and xflags)
- this is first version bump, backward compatibility on send and
receive side is provided
- there are still some known and wanted commands that will be
implemented in the near future, another version bump will be
needed, however we want to minimize that to avoid causing
usability issues
- print checksum type and implementation at mount time
- don't print some messages at mount (mentioned as people asked about
it), we want to print messages namely for new features so let's
make some space for that
- big metadata - this has been supported for a long time and is
not a feature that's worth mentioning
- skinny metadata - same reason, set by default by mkfs
Performance improvements:
- reduced amount of reserved metadata for delayed items
- when inserted items can be batched into one leaf
- when deleting batched directory index items
- when deleting delayed items used for deletion
- overall improved count of files/sec, decreased subvolume lock
contention
- metadata item access bounds checker micro-optimized, with a few
percent of improved runtime for metadata-heavy operations
- increase direct io limit for read to 256 sectors, improved
throughput by 3x on sample workload
Notable fixes:
- raid56
- reduce parity writes, skip sectors of stripe when there are no
data updates
- restore reading from on-disk data instead of using stripe cache,
this reduces chances to damage correct data due to RMW cycle
- refuse to replay log with unknown incompat read-only feature bit
set
- zoned
- fix page locking when COW fails in the middle of allocation
- improved tracking of active zones, ZNS drives may limit the
number and there are ENOSPC errors due to that limit and not
actual lack of space
- adjust maximum extent size for zone append so it does not cause
late ENOSPC due to underreservation
- mirror reading error messages show the mirror number
- don't fallback to buffered IO for NOWAIT direct IO writes, we don't
have the NOWAIT semantics for buffered io yet
- send, fix sending link commands for existing file paths when there
are deleted and created hardlinks for same files
- repair all mirrors for profiles with more than 1 copy (raid1c34)
- fix repair of compressed extents, unify where error detection and
repair happen
Core changes:
- bio completion cleanups
- don't double defer compression bios
- simplify endio workqueues
- add more data to btrfs_bio to avoid allocation for read requests
- rework bio error handling so it's same what block layer does,
the submission works and errors are consumed in endio
- when asynchronous bio offload fails fall back to synchronous
checksum calculation to avoid errors under writeback or memory
pressure
- new trace points
- raid56 events
- ordered extent operations
- super block log_root_transid deprecated (never used)
- mixed_backref and big_metadata sysfs feature files removed, they've
been default for sufficiently long time, there are no known users
and mixed_backref could be confused with mixed_groups
Non-btrfs changes, API updates:
- minor highmem API update to cover const arguments
- switch all kmap/kmap_atomic to kmap_local
- remove redundant flush_dcache_page()
- address_space_operations::writepage callback removed
- add bdev_max_segments() helper"

Pull efivars sysfs interface removal from Ard Biesheuvel:
"Remove the obsolete 'efivars' sysfs based interface to the EFI
variable store, now that all users have moved to the efivarfs pseudo

fundamental shortcomings in the sysfs based driver.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU updates from Paul McKenney:
- Documentation updates
- Miscellaneous fixes
- Callback-offload updates, perhaps most notably a new
RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to be
offloaded at boot time, regardless of kernel boot parameters.
This is useful to battery-powered systems such as ChromeOS and
Android. In addition, a new RCU_NOCB_CPU_CB_BOOST kernel boot
parameter prevents offloaded callbacks from interfering with
real-time workloads and with energy-efficiency mechanisms
- Polled grace-period updates, perhaps most notably making these APIs
account for both normal and expedited grace periods
- Tasks RCU updates, perhaps most notably reducing the CPU overhead of
RCU tasks trace grace periods by more than a factor of two on a
system with 15,000 tasks.
The reduction is expected to increase with the number of tasks, so it
seems reasonable to hypothesize that a system with 150,000 tasks
might see a 20-fold reduction in CPU overhead
- Torture-test updates
- Updates that merge RCU's dyntick-idle tracking into context tracking,
thus reducing the overhead of transitioning to kernel mode from
either idle or nohz_full userspace execution for kernels that track
context independently of RCU.

Pull random number generator updates from Jason Donenfeld:
"Though there's been a decent amount of RNG-related development during
this last cycle, not all of it is coming through this tree, as this
cycle saw a shift toward tackling early boot time seeding issues,
which took place in other trees as well.
Here's a summary of the various patches:
- The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
option have been removed, as they overlapped with the more widely
supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
"random.trust_cpu". This change allowed simplifying a bit of arch
code.
- x86's RDRAND boot time test has been made a bit more robust, with
RDRAND disabled if it's clearly producing bogus results. This would
be a tip.git commit, technically, but I took it through random.git
to avoid a large merge conflict.
- The RNG has long since mixed in a timestamp very early in boot, on
the premise that a computer that does the same things, but does so
starting at different points in wall time, could be made to still
produce a different RNG state. Unfortunately, the clock isn't set
early in boot on all systems, so now we mix in that timestamp when
the time is actually set.
- User Mode Linux now uses the host OS's getrandom() syscall to
generate a bootloader RNG seed and later on treats getrandom() as
the platform's RDRAND-like faculty.
- The arch_get_random_{seed_,}_long() family of functions is now
arch_get_random_{seed_,}_longs(), which enables certain platforms,
such as s390, to exploit considerable performance advantages from
requesting multiple CPU random numbers at once, while at the same
time compiling down to the same code as before on platforms like
x86.
- A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
Uros.
- A comment spelling fix"

These drivers are rather uncomfortably hammered into the
address_space_operations hole. They aren't filesystems and don't behave
like filesystems. They just need their own movable_operations structure,
which we can point to directly from page->mapping.

Pull ARM boardfile deprecation from Arnd Bergmann:
"Over the past ten years, new machine support was based on device tree,
and an initial set of about 400 boards using ATAGS with boardfile for
booting were grandfathered in, with about half of them either removed
or converted to DT over time.
Based on the recent mailing list discussion I started, I have now
turned the findings into a set of patches that marks most board files
as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
For the boards that are marked as unused, there are two final chances
for potential users: The removal is scheduled to take place after the
longterm stable kernel at the end of 2022, so users can stay on that
version for another few years, and if anyone still has one of these
machines and is planning to keep updating kernels beyond that version,
they can speak up now to have their boards taken off the list again.
Waiting for the LTS release also makes sure that there will be at
least one longterm kernel that contains the recent multiplatform
conversion along while still supporting all legacy boards.
The short summary of the current status is:
- The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
users and will be removed entirely.
- The mmp and davinci platforms have DT support for the important
machines and will become DT-only after this.
- s3c64xx, dove, orion5x, and pxa keep some board files to allow
those to be migrated over to DT more easily, but most board files
are getting removed now. DT support on these platforms is partially
working but requires changes to additional drivers for the other
boards.
- omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
moment but have some boards with known users. Removing the board
files that nobody uses should make it easier to try a DT conversion
if anyone cares.
There is no explicit timeline what happens with the boards that remain
after this removal, but I expect to revisit this in the future, and
with most boards gone, there will be a good time to do a treewide
review of platform drivers that never gained DT support and have no
remaining in-tree board files"

Pull ARM DT updates from Arnd Bergmann:
"As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
added here in addition to the reference boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the Orange Pi
zero2 single-board computer and the X96 Mate set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers, DH
electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and
phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix
10 Software Virtual platform, both in the SoCFPGA platform.
- Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000
Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm SoC
families brought added machines: Acer Chromebook 514 (MT8192), Acer
Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines
including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips: PCB8309
(Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC
Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)"

Pull arm64 updates from Will Deacon:
"Highlights include a major rework of our kPTI page-table rewriting
code (which makes it both more maintainable and considerably faster in
the cases where it is required) as well as significant changes to our
early boot code to reduce the need for data cache maintenance and
greatly simplify the KASLR relocation dance.
Summary:
- Remove unused generic cpuidle support (replaced by PSCI version)
- Fix documentation describing the kernel virtual address space
- Handling of some new CPU errata in Arm implementations
- Rework of our exception table code in preparation for handling
machine checks (i.e. RAS errors) more gracefully
- Switch over to the generic implementation of ioremap()
- Fix lockdep tracking in NMI context
- Instrument our memory barrier macros for KCSAN
- Rework of the kPTI G->nG page-table repainting so that the MMU
remains enabled and the boot time is no longer slowed to a crawl
for systems which require the late remapping
- Enable support for direct swapping of 2MiB transparent huge-pages
on systems without MTE
- Fix handling of MTE tags with allocating new pages with HW KASAN
- Expose the SMIDR register to userspace via sysfs
- Continued rework of the stack unwinder, particularly improving the
behaviour under KASAN
- More repainting of our system register definitions to match the
architectural terminology
- Improvements to the layout of the vDSO objects
- Support for allocating additional bits of HWCAP2 and exposing
FEAT_EBF16 to userspace on CPUs that support it
- Considerable rework and optimisation of our early boot code to
reduce the need for cache maintenance and avoid jumping in and out
of the kernel when handling relocation under KASLR
- Support for disabling SVE and SME support on the kernel
command-line
- Support for the Hisilicon HNS3 PMU
- Miscellanous cleanups, trivial updates and minor fixes"

The root cause of the bug sits in neon_poly1305_blocks. The logic
neon_poly1305_blocks() performed is that if it was called with both s[]
and r[] uninitialized, it will first try to initialize them with the
data from the first "block" that it believed to be 32 bytes in length.
First 16 bytes are used as the key and the next 16 bytes for s[]. This
would lead to the aforementioned read out-of-bound. However, after
calling poly1305_init_arch(), only 16 bytes were deducted from the input
and s[] is initialized yet again with the following 16 bytes. The second
initialization of s[] is certainly redundent which indicates that the
first initialization should be for r[] only.
This patch fixes the issue by calling poly1305_init_arm64() instead of
poly1305_init_arch(). This is also the implementation for the same
algorithm on arm platform.

BIOS Information
Vendor: Loongson
Version: vUDK2018-LoongArch-V2.0.pre-beta8
Release Date: 06/15/2022
ROM Size: 4 MB
According to "BIOS Information (Type 0) structure" in the SMBIOS
Reference Specification [1], it shows 64K * (n+1) is the size of
the physical device containing the BIOS if the size is less than
16M.
Additionally, we can see the related code in dmidecode [2]:
u64 s = { .l = (code1 + 1) << 6 };
So the output of dmidecode is correct, the output of boardinfo
is wrong, fix it.
By the way, at present no need to consider the size is 16M or
greater on LoongArch, because it is usually 4M or 8M which is
enough to use.

In file ptrace.c, function fpr_set does not copy fcsr data from ubuf
to kbuf. That's the reason why fcsr cannot be modified by ptrace.

Current calculation of shared cache size is from the node (die) scope,
but we hope 'lscpu' to show the shared cache size of the whole package
for multi-die chips (e.g., Loongson-3C5000L, which contains 4 dies in
one package). So fix it by multiplying nodes_per_package.
