git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
"New features for ext4 this cycle include support for encrypted
casefold, ensure that deleted file names are cleared in directory
blocks by zeroing directory entries when they are unlinked or moved as
part of a hash tree node split. We also improve the block allocator's
performance on a freshly mounted file system by prefetching block
bitmaps.
There are also the usual cleanups and bug fixes, including fixing a
page cache invalidation race when there is mixed buffered and direct
I/O and the block size is less than page size, and allow the dax flag
to be set and cleared on inline directories"

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"There is a lot going on!
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls"
* tag 'pinctrl-v5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits)

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"No surprises in this development cycle, and most of work is about the
fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced. It is used by HD-audio
for now, more adaption will follow later. The former "Mic Mute-LED
Mode" mixer control has been replaced with the corresponding sysfs
now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements; this will allow more controls in
the normal usage pattern while avoiding the possible memory
exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates"

There are only two callers of __alloc_pages() so prune the thicket of
alloc_page variants by combining the two functions together. Current
callers of __alloc_pages() simply add an extra 'NULL' parameter and
current callers of __alloc_pages_nodemask() call __alloc_pages() instead.

Collect the time when each allocation is freed, to help with memory
analysis with kdump/ramdump. Add the timestamp also in the page_owner
debugfs file and print it in dump_page().
Having another timestamp when we free the page helps for debugging page
migration issues. For example both alloc and free timestamps being the
same can gave hints that there is an issue with migrating memory, as
opposed to a page just being dropped during migration.

Pull networking updates from Jakub Kicinski:
"Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to walk
all map elements in a more robust and easier to verify fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF on
s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices which don't
need headers in the linear skb part (e.g. virtio)

next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is slow in
reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR

- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take place
correctly even for encapsulated UDP traffic

retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls

Pull xfs updates from Darrick Wong:
"The notable user-visible addition this cycle is ability to remove
space from the last AG in a filesystem. This is the first of many
changes needed for full-fledged support for shrinking a filesystem.
Still needed are (a) the ability to reorganize files and metadata away
from the end of the fs; (b) the ability to remove entire allocation
groups; (c) shrink support for realtime volumes; and (d) thorough
testing of (a-c).
There are a number of performance improvements in this code drop: Dave
streamlined various parts of the buffer logging code and reduced the
cost of various debugging checks, and added the ability to pre-create
the xattr structures while creating files. Brian eliminated
transaction reservations that were being held across writeback (thus
reducing livelock potential.
Other random pieces: Pavel fixed the repetitve warnings about
deprecated mount options, I fixed online fsck to behave itself when a
readonly remount comes in during scrub, and refactored various other
parts of that code, Christoph contributed a lot of refactoring this
cycle. The xfs_icdinode structure has been absorbed into the (incore)
xfs_inode structure, and the format and flags handling around
xfs_inode_fork structures has been simplified. Chandan provided a
number of fixes for extent count overflow related problems that have
been shaken out by debugging knobs added during 5.12.
Summary:
- Various minor fixes in online scrub.
- Prevent metadata files from being automatically inactivated.
- Validate btree heights by the computed per-btree limits.
- Don't warn about remounting with deprecated mount options.
- Initialize attr forks at create time if we suspect we're going to
need to store them.
- Reduce memory reallocation workouts in the logging code.
- Fix some theoretical math calculation errors in logged buffers that
span multiple discontig memory ranges but contiguous ondisk
regions.
- Speedups in dirty buffer bitmap handling.
- Make type verifier functions more inline-happy to reduce overhead.
- Reduce debug overhead in directory checking code.
- Many many typo fixes.
- Begin to handle the permanent loss of the very end of a filesystem.
- Fold struct xfs_icdinode into xfs_inode.
- Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx
ioctl.
- Remove a broken directory block format check from online scrub.
- Fix a bug where we could produce an unnecessarily tall data fork
btree when creating an attr fork.
- Fix scrub and readonly remounts racing.
- Fix a writeback ioend log deadlock problem by dropping the behavior
where we could preallocate a setfilesize transaction.
- Fix some bugs in the new extent count checking code.
- Fix some bugs in the attr fork preallocation code.
- Refactor if_flags out of the incore inode fork data structure"

Pull clk updates from Stephen Boyd:
"Here's a collection of largely clk driver updates. The usual suspects
are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
but it feels pretty light on commits.
There's only one real commit to the framework core and that's to
consolidate code. Otherwise the diffstat is dominated by many Qualcomm
clk driver patches that modernize the driver for the proper way of
speciying clk parents. That's shifting data around, which could subtly
break things so I'll be on the lookout for fixes.
New Drivers:
- Proper clk driver for Mediatek MT7621 SoCs
- Support for the clock controller on the new Rockchip rk3568
Updates:
- Simplify Zynq Kconfig dependencies
- Use clk_hw pointers in socfpga driver
- Cleanup parent data in qcom clk drivers
- Some cleanups for rk3399 modularization
- Fix reparenting of i.MX UART clocks by initializing only the ones
associated to stdout
- Correct the PCIE clocks for i.MX8MP and i.MX8MQ
- Make i.MX LPCG and SCU clocks return on registering failure
- Kernel doc fixes
- Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
- Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
- Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on
Renesas R-Car V3U
- Sigma-delta modulation on Allwinner V3s audio PLL"

Daniel Borkmann says:
====================
pull-request: bpf-next 2021-04-28
The main changes are:
1) Add link detach and following re-attach for trampolines, from Jiri Olsa.
2) Use kernel's "binary printf" lib for formatted output BPF helpers (which
avoids the needs for variadic argument handling), from Florent Revest.
3) Fix verifier 64 to 32 bit min/max bound propagation, from Daniel Borkmann.
4) Convert cpumap to use netif_receive_skb_list(), from Lorenzo Bianconi.
5) Add generic batched-ops support to percpu array map, from Pedro Tammela.
6) Various CO-RE relocation BPF selftests fixes, from Andrii Nakryiko.
7) Misc doc rst fixes, from Hengqi Chen.
