asm-generic changes for 5.15
The main content for 5.15 is a series that cleans up the handling of
strncpy_from_user() and strnlen_user(), removing a lot of slightly
incorrect versions of these in favor of the lib/strn*.c helpers
that implement these correctly and more efficiently.
The only architectures that retain a private version now are
mips, ia64, um and parisc. I had offered to convert those at all,
but Thomas Bogendoerfer wanted to keep the mips version for the
moment until he had a chance to do regression testing.
The branch also contains two patches for bitops and for ffs().

Merge branch 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull exit cleanups from Eric Biederman: "In preparation of doing something about PTRACE_EVENT_EXIT I have started cleaning up various pieces of code related to do_exit. Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call |

signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die
In the fpsp040 code when copyin or copyout fails call
force_sigsegv(SIGSEGV) instead of do_exit(SIGSEGV).
This solves a couple of problems. Because do_exit embeds the ptrace
stop PTRACE_EVENT_EXIT a complete stack frame needs to be present for
that to work correctly. There is always the information needed for a
ptrace stop where get_signal is called. So exiting with a signal
solves the ptrace issue.
Further exiting with a signal ensures that all of the threads in a
process are killed not just the thread that malfunctioned. Which
avoids confusing userspace.
To make force_sigsegv(SIGSEGV) work in fpsp040_die modify the code to
save all of the registers and jump to ret_from_exception (which
ultimately calls get_signal) after fpsp040_die returns.
v2: Updated the branches to use gas's pseudo ops that automatically
calculate the best branch instruction to use for the purpose.

m68k: Fix asm register constraints for atomic ops
Depending on register assignment by the compiler:
{standard input}:3084: Error: operands mismatch -- statement `andl %a1,%d1' ignored
{standard input}:3145: Error: operands mismatch -- statement `orl %a1,%d1' ignored
{standard input}:3195: Error: operands mismatch -- statement `eorl %a1,%d1' ignored
Indeed, the first operand must not be an address register. However, it
can be an immediate value. Fix this by adjusting the register
constraint from "g" (general purpose register) to "di" (data register or
immediate).

asm-generic: reverse GENERIC_{STRNCPY_FROM,STRNLEN}_USER symbols
Most architectures do not need a custom implementation, and in most
cases the generic implementation is preferred, so change the polariy
on these Kconfig symbols to require architectures to select them when
they provide their own version.
The new name is CONFIG_ARCH_HAS_{STRNCPY_FROM,STRNLEN}_USER.
The remaining architectures at the moment are: ia64, mips, parisc,
um and xtensa. We should probably convert these as well, but
I was not sure how far to take this series. Thomas Bogendoerfer
had some concerns about converting mips but may still do some
more detailed measurements to see which version is better.

asm-generic: uaccess: remove inline strncpy_from_user/strnlen_user
The inline version is used on three NOMMU architectures and is particularly inefficient when it scans the string one byte at a time twice. It also lacks a check for user_addr_max(), but this is probably ok on NOMMU targets. Consolidate the asm-generic implementation with the library version that is used everywhere else. This version is generalized enough to work efficiently on both MMU and NOMMU targets, and using the same code everywhere reduces the potential for subtle bugs. Mark the prototypes as __must_check in the process.

tty: drop put_tty_driver

tty: don't store semi-state into tty drivers
When a tty driver pointer is used as a return value of struct console's device() hook, don't store a semi-state into global variable which holds the tty driver. It could mean console::device() would return a bogus value. This is important esp. after the next patch where we switch from alloc_tty_driver to tty_alloc_driver. tty_alloc_driver returns ERR_PTR in case of error and that might have unexpected results as the code doesn't expect this.

asm-generic/unaligned: Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally architecture specific, with the two main variants being the "access-ok.h" version that assumes unaligned pointer accesses always work on a particular architecture, and the "le-struct.h" version that casts the data to a byte aligned type before dereferencing, for architectures that cannot always do unaligned accesses in hardware.

This round has a diffstat dominated by Qualcomm clk drivers. Honestly though
that's just a bunch of data so the diffstat reflects that. Looking beyond that
there's just a bunch of updates all around in various clk drivers. Renesas and
NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall
the driver changes look to be mostly enabling more clks and non-critical fixes
that we could hold until the next merge window.
I'm especially excited about the series from Arnd that graduates clkdev to be
the only implementation of clk_get() and clk_put(). That's a good step in the
right direction to migreate eveerything over to the common clk framework. Now
we don't have to worry about clkdev specific details, they're just part of the
clk API now.
Core:
- clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in
only one place in the kernel instead of in drivers/clk/clkdev.c and in
architectures that want their own implementation
New Drivers:
- Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock
Jitter Cleaner With Dual Loop PLLs
- Qualcomm MDM9607 GCC
- Qualcomm SC8180X display clks
- Qualcomm SM6125 GCC
- Qualcomm SM8250 CAMCC (camera)
- Renesas RZ/G2L SoC
- Hisilicon hi3559A SoC
Updates:
- Stop using clock-output-names in ST clk drivers (yay!)
- Support secure mode of STM32MP1 SoCs
- Improve clock support for Actions S500 SoC
- duty cycle setting support on qcom clks
- Add TI am33xx spread spectrum clock support
- Use determine_rate() for the Amlogic pll ops instead of round_rate()
- Restrict Amlogic gp0/1 and audio plls range on g12a/sm1
- Improve Amlogic axg-audio controller error on deferral
- Add NNA clocks on Amlogic g12a
- Reduce memory footprint of Rockchip PLL rate tables
- A fix for the newly added Rockchip rk3568 clk driver
- Exported clock for the newly added Rockchip video decoder
- Remove audio ipg clock from i.MX8MP
- Remove deprecated legacy clock binding for i.MX SCU clock driver
- Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM
- Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif, audio,
parallel interface)
- Add dedicated clock ops for i.MX paralel interface
- Different fixes for clocks controlled by ATF on i.MX SoCs
- Add A53/A72 frequency scaling support i.MX clk-scu driver
- Add special case for DCSS clock on suspend for i.MX clk-scu driver
- Add parent save/restore on suspend/resume to i.MX clk-scu driver
- Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver
- Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their
bindings
- Tegra clk driver no longer deasserts resets on clk_enable as it
gets in the way of certain power-up sequences
- Fix compile testing for Tegra clk driver
- One patch to fix a divider on the Allwinner v3s Audio PLL
- Add support for CPU core clock boost modes on Renesas R-Car Gen3
- Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U
- Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate()
and improve support for multiple parents
- Switch Renesas RZ/N1 divider clocks to .determine_rate()
- Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3
- Convert ar7 to common clk framework
- Convert ralink to common clk framework

mm/thp: define default pmd_pgtable()
Currently most platforms define pmd_pgtable() as pmd_page() duplicating the same code all over. Instead just define a default value i.e pmd_page() for pmd_pgtable() and let platforms override when required via <asm/pgtable.h>. All the existing platform that override pmd_pgtable() have been moved into their respective <asm/pgtable.h> header in order to precede before the new generic definition.

Pull arm64 updates from Will Deacon:
"There's a reasonable amount here and the juicy details are all below.
It's worth noting that the MTE/KASAN changes strayed outside of our
usual directories due to core mm changes and some associated changes
to some other architectures; Andrew asked for us to carry these [1]
rather that take them via the -mm tree.
Summary:
- Optimise SVE switching for CPUs with 128-bit implementations.
- Fix output format from SVE selftest.
- Add support for versions v1.2 and 1.3 of the SMC calling
convention.
- Allow Pointer Authentication to be configured independently for

Scheduler udpates for this cycle:
- Changes to core scheduling facilities:
- Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
coordinated scheduling across SMT siblings. This is a much
requested feature for cloud computing platforms, to allow
the flexible utilization of SMT siblings, without exposing
untrusted domains to information leaks & side channels, plus
to ensure more deterministic computing performance on SMT
systems used by heterogenous workloads.
There's new prctls to set core scheduling groups, which
allows more flexible management of workloads that can share
siblings.
- Fix task->state access anti-patterns that may result in missed
wakeups and rename it to ->__state in the process to catch new
abuses.
- Load-balancing changes:
- Tweak newidle_balance for fair-sched, to improve
'memcache'-like workloads.
- "Age" (decay) average idle time, to better track & improve workloads
such as 'tbench'.
- Fix & improve energy-aware (EAS) balancing logic & metrics.
- Fix & improve the uclamp metrics.
- Fix task migration (taskset) corner case on !CONFIG_CPUSET.
- Fix RT and deadline utilization tracking across policy changes
- Introduce a "burstable" CFS controller via cgroups, which allows
bursty CPU-bound workloads to borrow a bit against their future
quota to improve overall latencies & batching. Can be tweaked
via /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.
- Rework assymetric topology/capacity detection & handling.
- Scheduler statistics & tooling:
- Disable delayacct by default, but add a sysctl to enable
it at runtime if tooling needs it. Use static keys and
other optimizations to make it more palatable.
- Use sched_clock() in delayacct, instead of ktime_get_ns().
- Misc cleanups and fixes.
