Vendor events:
- Intel Alderlake/Sapphire Rapids metric fixes, the CPU type ("cpu_atom", "cpu_core")
needs to be used as a prefix to be considered on a metric formula, detected via one
of the 'perf test' entries.
'perf test' fixes:
- Fix the creation of event selector lists on 'perf test' entries, by initializing
the sample ID flag, which is done by 'perf record', so this fix only the tests,
the common case isn't affected.
- Make 'perf list' respect debug settings (-v) to fix its 'perf test' entry.
- Fix 'perf script' test when python support isn't enabled.
- Special case 'perf script' tests on s390, where only DWARF call graphs are
supported and only on software events.
- Make 'perf daemon' signal test less racy.
Compiler warnings/errors:
- Remove needless malloc(0) call in 'perf top' that triggers -Walloc-size.
- Fix calloc() argument order to address error introduced in gcc-14.
Build:
- Make minimal shellcheck version to v0.6.0, avoiding the build to fail with older versions.
Sync kernel header copies:
- stat.h to pick STATX_MNT_ID_UNIQUE.
- msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING.
- drm.h to pick DRM_IOCTL_MODE_CLOSEFB.
- unistd.h to pick {list,stat}mount, lsm_{[gs]et_self_attr,list_modules} syscall numbers.
- x86 cpufeatures to pick TDX, Zen, APIC MSR fence changes.
- x86's mem{cpy,set}_64.S used in 'perf bench'.
- Also, without tooling effects: asm-generic/unaligned.h, mount.h, fcntl.h, kvm headers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
