- Fix SMT detection fast read path on sysfs. - Fix memory leaks when processing feature headers in perf.data files. - Fix 'Simple expression parser' 'perf test' on arch without CPU die topology info, such as s/390. - Fix building perf with BUILD_BPF_SKEL=1. - Fix 'perf bench' by reverting "perf bench: Fix two memory leaks detected with ASan". - Fix itrace space allowed for new attributes in 'perf script'. - Fix the build feature detection fast path, that was always failing on systems with python3 development packages, speeding up the build. - Reset shadow counts before loading, fixing metrics using duration_time. - Sync more kernel headers changed by the new futex_waitv syscall: s390 and powerpc.

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.
