- During this merge window O_NONBLOCK was changed to become 000200000,
but we missed that the syscalls timerfd_create(), signalfd4(),
eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
bit-wise check of the flags parameter.
To provide backward compatibility with existing userspace we
introduce parisc specific wrappers for those syscalls which filter
out the old O_NONBLOCK value and replaces it with the new one.

This is the cleanup of the latest series of prandom_u32 experimentations
consisting in using SipHash instead of Tausworthe to produce the randoms
used by the network stack. The changes to the files were kept minimal,
and the controversial commit that used to take noise from the fast_pool
(f227e3ec3b) was reverted. Instead, a dedicated "net_rand_noise" per_cpu
variable is fed from various sources of activities (networking, scheduling)
to perturb the SipHash state using fast, non-trivially predictable data,
instead of keeping it fully deterministic. The goal is essentially to make
any occasional memory leakage or brute-force attempt useless.
The resulting code was verified to be very slightly faster on x86_64 than
what is was with the controversial commit above, though this remains barely
above measurement noise. It was also tested on i386 and arm, and build-
tested only on arm64.

Commit 21653a4181 ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.

Non-cryptographic PRNGs may have great statistical properties, but
are usually trivially predictable to someone who knows the algorithm,
given a small sample of their output. An LFSR like prandom_u32() is
particularly simple, even if the sample is widely scattered bits.
It turns out the network stack uses prandom_u32() for some things like
random port numbers which it would prefer are *not* trivially predictable.
Predictability led to a practical DNS spoofing attack. Oops.
This patch replaces the LFSR with a homebrew cryptographic PRNG based
on the SipHash round function, which is in turn seeded with 128 bits
of strong random key. (The authors of SipHash have *not* been consulted
about this abuse of their algorithm.) Speed is prioritized over security;
attacks are rare, while performance is always wanted.
Replacing all callers of prandom_u32() is the quick fix.
Whether to reinstate a weaker PRNG for uses which can tolerate it
is an open question.
Commit f227e3ec3b ("random32: update the net random state on interrupt
and activity") was an earlier attempt at a solution. This patch replaces
it.

- Support for Nvidia Tegra234 SoC
- Ring accelerator support for TI AM65x
- PRUSS driver for TI platforms
- Renesas support for R-Car V3U SoC
- Reset support for Cortex-M4 processor on i.MX8MQ
There are also new socinfo entries for a handful of different SoCs

- A bunch of cleanup and removal of platform data for TI/OMAP platforms,
moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them

The set of core changes here is Christoph's submission path cleanups.
These introduced a couple of regressions when first proposed so they
got held over from the initial merge window pull request to give more
testing time, which they've now had and Syzbot has confirmed the
regression it detected is fixed. The other main changes are two
driver updates (arcmsr, pm80xx) and assorted minor clean ups.

Current release - regressions:
- Revert "virtio-net: ethtool configurable RXCSUM", it was causing

Previous releases - regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO

- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu()

- icmp: randomize the global rate limiter to prevent attackers from

- r8169: fix operation under forced interrupt threading, make the

We've had several complaints about a 10s reconnect delay (the default)
when there was an error while there is connectivity to a subsystem.
The max_reconnects and reconnect_delay are set in common code prior to
calling the transport to create the controller.
This change checks if the default reconnect delay is being used, and if
so, it adjusts it to a shorter period (2s) for the nvme-fc transport.
It does so by calculating the controller loss tmo window, changing the
value of the reconnect delay, and then recalculating the maximum number
of reconnect attempts allowed.

Currently, an I/O timeout unconditionally invokes
nvme_fc_error_recovery() which checks for LIVE or CONNECTING state. If
live, the routine resets the controller which initiates a reconnect -
which is valid. If CONNECTING, err_work is scheduled. Err_work then
calls the terminate_io routine, which also checks for CONNECTING and
noops any further action on outstanding I/O. The result is nothing
happened to the timed out io. As such, if the command was dropped on
the wire, it will never timeout / complete, and the connect process
will hang.
Change the behavior of the io timeout routine to unconditionally abort
the I/O. I/O completion handling will note that an io failed due to an
abort and will terminate the connection / association as needed. If the
abort was unable to happen, continue with a call to
nvme_fc_error_recovery(). To ensure something different happens in
nvme_fc_error_recovery() rework it so at it will abort all I/Os on the
association to force a failure.
As I/O aborts now may occur outside of delete_association, counting for
completion must be wary and only count those aborted during
delete_association when TERMIO is set on the controller.

When starting a HP machine with HIL driver but without an HIL keyboard
or HIL mouse attached, it may happen that data written to the HIL loop
gets stuck (e.g. because the transaction queue is full). Usually one
will then have to reboot the machine because all you see is and endless
output of:
Transaction add failed: transaction already queued?
In the higher layers hp_sdc_enqueue_transaction() is called to queued up
a HIL packet. This function returns an error code, and this patch adds
the necessary checks for this return code and disables the HIL driver if
further packets can't be sent.
Tested on a HP 730 and a HP 715/64 machine.

"This introduces rpmsg_char support for GLINK and fixes a few issues"
* tag 'rpmsg-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc:
rpmsg: glink: Expose rpmsg name attr for glink
rpmsg: glink: Add support for rpmsg glink chrdev

rpmsg: smd: Fix a kobj leak in in qcom_smd_parse_edge()
This introduces support for the Mediatek MT9182 SCP and controlling the
Cortex R5F processors found in TI K3 platforms. It clones the
longstanding debugfs interface for controlling crash handling to sysfs.
Lastly it solves a bug where after a warm reset of Qualcomm platforms
the modem would crash upon first boot.

of various clk driver updates. The biggest driver updates in terms of lines of
code is the Allwinner driver, closely followed by the Qualcomm and Mediatek
drivers. All of those hit high because we add so many lines of clk data. Coming
in fourth place is i.MX which also adds a bunch of clk data. This accounts for
the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for various clk
drivers that have baked in linux-next for a while. I suppose one highlight or
theme is that more clk drivers are being updated to work as modules, which is
interesting to see such critical SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module
- Some kerneldoc fixes here and there
- A couple of minor i.MX clk data corrections
- Update audio clock inverter and fdiv2 flag on Amlogic g12
- Make amlogic clk drivers configurable in Kconfig
- Fix Renesas VSP clock names to match corrected hardware documentation
- Sigma-delta modulation on Allwinner R40
- Various fixes for at91 clk driver
- Use semicolons instead of commas in some places
- Mark some variables const so they can move to RO memory

All avs drivers have now been moved to their corresponding soc specific
directories. Additionally, they don't depend on the POWER_AVS Kconfig
anymore. Therefore, let's simply drop the drivers/power/avs directory
altogether.
