Add the -a/--auto <arg in us> option. This option sets some commonly
used options while debugging the system. It aims to help users produce
reports in the field, reducing the number of arguments passed to the
tool in the first approach to a problem.
It is equivalent to setting osnoise/stop_tracing_total_us and print_stack
with the argument, and saving the trace to timerlat_trace.txt file if the
trace is stopped automatically.

It is equivalent to setting osnoise/stop_tracing_us with the argument,

Add the -T/--threshold option to set the minimum threshold to be
considered a noise to osnoise top and hist commands. Also update

Currently, --entries uses -e as the short version in the hist mode of
timerlat and osnoise tools. But as -e is already used to enable events
on trace sessions by other tools, thus let's keep it available for the
same usage for all rtla tools.
Make -E the short version of --entries for hist mode on all tools.
Note: rtla was merged in this merge window, so rtla was not released yet.

Patch series "remove Xen tmem leftovers".
Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap. This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.
This patch (of 13):
The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49dcd0 ("xen: remove tmem driver").

This patchset allows to have a single kernel for sv39 and sv48 without
being relocatable.
The idea comes from Arnd Bergmann who suggested to do the same as x86,
that is mapping the kernel to the end of the address space, which allows
the kernel to be linked at the same address for both sv39 and sv48 and
then does not require to be relocated at runtime.
This implements sv48 support at runtime. The kernel will try to boot
with 4-level page table and will fallback to 3-level if the HW does not
support it. Folding the 4th level into a 3-level page table has almost
no cost at runtime.
Note that kasan region had to be moved to the end of the address space
since its location must be known at compile-time and then be valid for
both sv39 and sv48 (and sv57 that is coming).
* riscv-sv48-v3:
riscv: Explicit comment about user virtual address space size
riscv: Use pgtable_l4_enabled to output mmu_type in cpuinfo
riscv: Implement sv48 support
asm-generic: Prepare for riscv use of pud_alloc_one and pud_free
riscv: Allow to dynamically define VA_BITS
riscv: Introduce functions to switch pt_ops
riscv: Split early kasan mapping to prepare sv48 introduction
riscv: Move KASAN mapping next to the kernel mapping
riscv: Get rid of MAXPHYSMEM configs

Now that KASAN_SHADOW_OFFSET is defined at compile time as a config,
this value must remain constant whatever the size of the virtual address
space, which is only possible by pushing this region at the end of the
address space next to the kernel mapping.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've tried to address some performance issues in
f2fs_checkpoint and direct IO flows. Also, there was a work to enhance
the page cache management used for compression. Other than them, we've
done typical work including sysfs, code clean-ups, tracepoint, sanity
check, in addition to bug fixes on corner cases.
Enhancements:
- use iomap for direct IO
- try to avoid lock contention to improve f2fs_ckpt speed
- avoid unnecessary memory allocation in compression flow
- POSIX_FADV_DONTNEED drops the page cache containing compression
pages
- add some sysfs entries (gc_urgent_high_remaining, pending_discard)
Bug fixes:
- try not to expose unwritten blocks to user by DIO (this was added
to avoid merge conflict; another patch is coming to address other
missing case)
- relax minor error condition for file pinning feature used in
Android OTA
- fix potential deadlock case in compression flow
- should not truncate any block on pinned file

Pull more ACPI updates from Rafael Wysocki:
"The most significant item here is the Platform Firmware Runtime Update
and Telemetry (PFRUT) support designed to allow certain pieces of the
platform firmware to be updated on the fly, among other things.
Also important is the e820 handling change on x86 that should work
around PCI BAR allocation issues on some systems shipping since 2019.
The rest is just a handful of assorted fixes and cleanups on top of
the ACPI material merged previously.
Specifics:
- Add support for the the Platform Firmware Runtime Update and
Telemetry (PFRUT) interface based on ACPI to allow certain pieces
of the platform firmware to be updated without restarting the
system and to provide a mechanism for collecting platform firmware
telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
- Ignore E820 reservations covering PCI host bridge windows on
sufficiently recent x86 systems to avoid issues with allocating PCI
BARs on systems where the E820 reservations cover the entire PCI
host bridge memory window returned by the _CRS object in the
system's ACPI tables (Hans de Goede).
- Fix and clean up acpi_scan_init() (Rafael Wysocki).
- Add more sanity checking to ACPI SPCR tables parsing (Mark
Langsdorf).
- Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
- Drop unnecessary "static" from the ACPI PCC address space handling
driver added recently (kernel test robot)"
