Pull perf tools fixes from Arnaldo Carvalho de Melo:
"Perf tool fixes:
- Fix wrong skipping for per-die aggregation in 'perf stat'.
- Fix race in signal handling on large core count machines, setting
up signal handlers earlier.
- Fix -F for branch & mem modes in 'perf report'.
- Fix the condition checks for max number of NUMA nodes in 'perf
bench numa'.
- Fix crash in 'perf diff' error path.
- Fix filtering of empty build-ids in 'perf archive'.
- Ensure read cmdlines from libtraceevent are null terminated.
Recent regressions:
- Fix control fifo permissions in 'perf daemon'.
- Fix 'perf daemon' compile error with ASAN.
- Fix running 'perf daemon' test for non root user.
- Fix PERF_SAMPLE_WEIGHT_STRUCT 'perf test' failure on non-x86
arches.
- Fix event's PMU name parsing related to new drm/i915/gt
software-gt-awake-time event.
Fixes from compiler instrumentation:
- Fix leaks in 'perf test' entries, found using ASAN.
- Fix use-after-free when 'perf stat -r' option is used.
Arch specific:
- Fix bitmap for option om ARM's CS-ETM.
Documentation:
- Fix documentation of verbose options.
Build:
- Clean 'generated' directory used for creating the syscall table on
x86.
- Fix ccache usage in $(CC) when generating arch errno table.
- Cast (struct timeval).tv_sec when printing, fixing the build with
MUSL libc.
- Tighten snprintf() string precision to pass gcc check on some
32-bit arches.
- Update UAPI copies from the kernel sources.
- Fix regression on feature detection 'make clean' target"

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.
