Pull thread management updates from Christian Brauner:
- A pidfd's fdinfo file currently contains the field "Pid:\t<pid>"
where <pid> is the pid of the process in the pid namespace of the
procfs instance the fdinfo file for the pidfd was opened in.
The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]"
field which lists the pids of the process in all child pid namespaces
provided the pid namespace of the procfs instance it is looked up
under has an ancestoral relationship with the pid namespace of the
process. If it does not 0 will be shown and no further pid namespaces
will be listed. Tests included. (Christian Kellner)
- If the process the pidfd references has already exited, print -1 for
the Pid and NSpid fields in the pidfd's fdinfo file. Tests included.
(me)
- Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler
that are not SIG_DFL or SIG_IGN at process creation time. This
originated as a feature request from glibc to improve performance and
elimate races in their posix_spawn() implementation. Tests included.
(me)
- Add support for choosing a specific pid for a process with clone3().
This is the feature which was part of the thread update for v5.4 but
after a discussion at LPC in Lisbon we decided to delay it for one
more cycle in order to make the interface more generic. This has now
done. It is now possible to choose a specific pid in a whole pid
namespaces (sub)hierarchy instead of just one pid namespace. In order
to choose a specific pid the caller must have CAP_SYS_ADMIN in all
owning user namespaces of the target pid namespaces. Tests included.
(Adrian Reber)
- Test improvements and extensions. (Andrei Vagin, me)

Pull arm64 updates from Catalin Marinas:
"Apart from the arm64-specific bits (core arch and perf, new arm64
selftests), it touches the generic cow_user_page() (reviewed by
Kirill) together with a macro for x86 to preserve the existing
behaviour on this architecture.
Summary:
- On ARMv8 CPUs without hardware updates of the access flag, avoid
failing cow_user_page() on PFN mappings if the pte is old. The
patches introduce an arch_faults_on_old_pte() macro, defined as
false on x86. When true, cow_user_page() makes the pte young before
attempting __copy_from_user_inatomic().
- Covert the synchronous exception handling paths in
arch/arm64/kernel/entry.S to C.
- FTRACE_WITH_REGS support for arm64.
- ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4
- Several kselftest cases specific to arm64, together with a
MAINTAINERS update for these files (moved to the ARM64 PORT entry).
- Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
instructions under certain conditions.
- Workaround for Cortex-A57 and A72 errata where the CPU may
speculatively execute an AT instruction and associate a VMID with
the wrong guest page tables (corrupting the TLB).
- Perf updates for arm64: additional PMU topologies on HiSilicon
platforms, support for CCN-512 interconnect, AXI ID filtering in
the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.
- GICv3 optimisation to avoid a heavy barrier when accessing the
ICC_PMR_EL1 register.
- ELF HWCAP documentation updates and clean-up.
- SMC calling convention conduit code clean-up.
- KASLR diagnostics printed during boot
- NVIDIA Carmel CPU added to the KPTI whitelist
- Some arm64 mm clean-ups: use generic free_initrd_mem(), remove
stale macro, simplify calculation in __create_pgd_mapping(), typos.
- Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for
endinanness to help with allmodconfig"

Pull io_uring updates from Jens Axboe:
"A lot of stuff has been going on this cycle, with improving the
support for networked IO (and hence unbounded request completion
times) being one of the major themes. There's been a set of fixes done
this week, I'll send those out as well once we're certain we're fully
happy with them.
This contains:
- Unification of the "normal" submit path and the SQPOLL path (Pavel)
- Support for sparse (and bigger) file sets, and updating of those
file sets without needing to unregister/register again.
- Independently sized CQ ring, instead of just making it always 2x
the SQ ring size. This makes it more flexible for networked
applications.
- Support for overflowed CQ ring, never dropping events but providing
backpressure on submits.
- Add support for absolute timeouts, not just relative ones.
- Support for generic cancellations. This divorces io_uring from
workqueues as well, which additionally gets us one step closer to
generic async system call support.
- With cancellations, we can support grabbing the process file table
as well, just like we do mm context. This allows support for system
calls that create file descriptors, like accept4() support that's
built on top of that.
- Support for io_uring tracing (Dmitrii)
- Support for linked timeouts. These abort an operation if it isn't
completed by the time noted in the linke timeout.
- Speedup tracking of poll requests
- Various cleanups making the coder easier to follow (Jackie, Pavel,
Bob, YueHaibing, me)
- Update MAINTAINERS with new io_uring list"

As presented at the 2018 Linux Plumbers conference [1], the Maintainer
Entry Profile (formerly Subsystem Profile) is proposed as a way to reduce
friction between committers and maintainers and encourage conversations
amongst maintainers about common best practices. While coding-style,
submit-checklist, and submitting-drivers lay out some common expectations
there remain local customs and maintainer preferences that vary by
subsystem.
The profile contains documentation of some of the common policy
questions a contributor might have that are local to the subsystem /
device-driver, special considerations for the subsystem, or other
guidelines that are otherwise not covered by the top-level process
documents.
The initial and hopefully non-controversial headings in the profile are:
Overview:
General introduction to how the subsystem operates
Submit Checklist Addendum:
Mechanical items that gate submission staging, or other requirements
that gate patch acceptance.
Key Cycle Dates:
- Last -rc for new feature submissions: Expected lead time for submissions
- Last -rc to merge features: Deadline for merge decisions
Resubmit Cadence: When and preferred method to follow up with the
maintainer
Note that coding style guidelines are explicitly left out of this list.
See Documentation/maintainer/maintainer-entry-profile.rst for more details,
and a follow-on example profile for the libnvdimm subsystem.

This supports an Ethernet switching core from Vitesse / Microsemi /
Microchip (VSC9959) which is part of the Ocelot family (a brand name),
and whose code name is Felix. The switch can be (and is) integrated on
different SoCs as a PCIe endpoint device.
The functionality is provided by the core of the Ocelot switch driver
(drivers/net/ethernet/mscc). In this regard, the current driver is an
instance of Microsemi's Ocelot core driver, with a DSA front-end. It
inherits its name from VSC9959's code name, to distinguish itself from
the switchdev ocelot driver.
The patch adds the logic for probing a PCI device and defines the
register map for the VSC9959 switch core, since it has some differences
in register addresses and bitfield mappings compared to the other Ocelot
switches (VSC7511, VSC7512, VSC7513, VSC7514).
The Felix driver declares the register map as part of the "instance
table". Currently the VSC9959 inside NXP LS1028A is the only instance,
but presumably it can support other switches in the Ocelot family, when
used in DSA mode (Linux running on the external CPU, and not on the
embedded MIPS).
In a few cases, some h/w operations have to be done differently on
VSC9959 due to missing bitfields. This is the case for the switch core
reset and init. Because for this operation Ocelot uses some bits that
are not present on Felix, the latter has to use a register from the
global registers block (GCB) instead.
Although it is a PCI driver, it relies on DT bindings for compatibility
with DSA (CPU port link, PHY library). It does not have any custom
device tree bindings, since we would like to minimize its dependency on
device tree though.

While it is entirely possible that this tagger format is in fact more
generic than just these 2 switch families, I don't have that knowledge.
The Seville switch in NXP T1040 has a similar frame format, but there
are enough differences (e.g. DEST field starts at bit 57 instead of 56)
that calling this file tag_vitesse.c is a bit of a stretch at the
moment. The frame format has been listed in a comment so that people who
add support for further Vitesse switches can rework this tagger while
keeping compatibility with Felix.
The "ocelot" name was chosen instead of "felix" because even the Ocelot
switch can act as a DSA device when it is used in NPI mode, and the Felix
tagger format is almost identical. Currently it is only used for the
Felix switch embedded in the NXP LS1028A chip.
The ABI for this tagger should be considered "not stable" at the moment.
The DSA tag is always placed before the Ethernet header and therefore,
we are using the long prefix for RX tags to avoid putting the DSA master
port in promiscuous mode. Once there will be an API in DSA for drivers
to request DSA masters to be in promiscuous mode unconditionally, we
will switch to the "no prefix" extraction frame header, which will save
16 padding bytes for each RX frame.
