As described in buffer-format.rst, the existing initramfs.c extraction
logic works fine if the cpio filename field is padded out with trailing
zeros, with a caveat that the padded namesize can't exceed PATH_MAX.
Add filename zero-padding logic to gen_init_cpio, which can be triggered
via the new -a <data_align> parameter. Performance and storage
utilization is improved for Btrfs and XFS workloads, as copy_file_range
can reflink the entire source file into a filesystem block-size aligned
destination offset within the cpio archive.

The alignment is best-effort; a stderr message is printed if alignment
can't be achieved due to PATH_MAX overrun, with fallback to non-padded
filename. This allows it to still be useful for opportunistic alignment,
e.g. on aarch64 Btrfs with 64K block-size. Alignment failure messages
provide an indicator that reordering of the cpio-manifest may be
beneficial.
Archive read performance for reflinked initramfs images may suffer due
to the effects of fragmentation, particularly on spinning disks. To
mitigate excessive fragmentation, files with lengths less than
data_align aren't padded.

The existing cpio extraction logic reads (maximum PATH_MAX) name_len
bytes from the archive into the collected name buffer and ensures that
the trailing byte is a null-terminator. This allows the actual file name
to be shorter than name_len, with the name string simply zero-terminated
prior to the last byte.
Initramfs generators, such as dracut-cpio[1], can take advantage of name
zero-padding to align file data segments within the archive to
filesystem block boundaries. Block boundary alignment may allow the
copy_file_range syscall to reflink archive source and destination
extents.

The copy_file_range syscall can improve copy performance by cloning
extents between cpio archive source and destination files.
Existing read / write based copy logic is retained for fallback in case
the copy_file_range syscall is unsupported or unavailable due to
cross-filesystem EXDEV, etc.
Clone or reflink, as opposed to copy, of source file extents into the
output cpio archive may (e.g. on Btrfs and XFS) require alignment of the
output to the filesystem block size. This could be achieved by inserting
padding entries into the cpio archive manifest.

When qconf (xconfig) exits, it saves the current Option settings
for Show Name, Show Debug Info, and Show {Normal|All|Prompt} Options.
When it is next run, it loads these Option settings from its
config file. It correctly shows the flag settings for Show Name
and Show Debug Info, but it does not show which of the 3 Show...Options
is set. This can lead to confusing output, e.g., if the user thinks
that xconfig is in Show All Options mode but kconfig options which
have an unmet dependency are still being listed.
Add code to show the radio button for the current Show...Options
mode during startup so that it will reflect the current config

compile_commands.json can be used with clangd to enable language server

BPF selftests) can benefit from their own compilation database file,
which can be generated successfully using external tools, like bear [0].
So, instead of adding compile_commands.json to .gitignore in respective
individual projects, let's just ignore it globally anywhere in Linux repo.
While at it, remove exactly such a local .gitignore rule under

Non-root turbostat users see complaints in this scenario.
Fail probe of the interface if we can't read current_freq_khz.

Together with the RAPL MSRs, there are more MSRs gone on DMR, including
PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response
Time Limit) MSRs. The configurable TDP info should also be retrieved
from TPMI based Intel Speed Select Technology feature.
Remove the access of these MSRs for DMR. Improve the DMR platform
feature table to make it more readable at the same time.

We have out-grown the ability to use a 64-bit memory location
to inventory every possible built-in counter.
Leverage the the CPU_SET(3) macros to break this barrier.
Also, break the Joules & Watts counters into two,
since we can no longer 'or' them together...

Here is a single revert of one of the previous patches that went in the
last tty/serial merge that is breaking userspace on some platforms
(specifically powerpc, probably a few others.) It accidentially changed
the ioctl values of some tty ioctls, which breaks xorg.
The revert has been in linux-next all this week with no reported issues.

Pull io_uring fixes from Jens Axboe:
- Allow vectorized payloads for send/send-zc - like sendmsg, but
without the hassle of a msghdr.
- Fix for an integer wrap that should go to stable, spotted by syzbot.
Nothing alarming here, as you need to be root to hit this.
Nevertheless, it should get fixed.
FWIW, kudos to the syzbot crew for having much nicer reproducers now,
and with nicely annotated source code as well. This is particularly
useful as syzbot uses the raw interface rather than liburing,
historically it's been difficult to turn a syzbot reproducer into a
meaningful test case. With the recent changes, not true anymore!
