Arnaldo Carvalho de Melo 11ba17769e perf MANIFEST: Add arch/*/include/uapi/asm/bpf_perf_event.h to the perf tarball 
[ Upstream commit 74c033b6aa ]

Needed to build tools/lib/bpf/ on various arches other than x86_64,
notably arm64 when using the perf tarballs generated by:

  $ make help | grep perf-
    perf-tar-src-pkg    - Build the perf source tarball with no compression
    perf-targz-src-pkg  - Build the perf source tarball with gzip compression
    perf-tarbz2-src-pkg - Build the perf source tarball with bz2 compression
    perf-tarxz-src-pkg  - Build the perf source tarball with xz compression
    perf-tarzst-src-pkg - Build the perf source tarball with zst compression
  $

Building with BPF support was opt-in in perf for a long time, and
testing it via the tarball main kernel Makefile targets in an
architecture other than x86_64 was an odd case.

I had noticed this at some point earlier this year while cross building
perf to some arches, including arm64, but it fell thru the cracks, see
the Link tag below.

Fix it now by adding those arch/*/include/uapi/asm/bpf_perf_event.h
files to the MANIFEST file used in building the perf source tarball.

Tested with:

  perfbuilder@number:~$ time dm debian:experimental-x-arm64
     1    21.60 debian:experimental-x-arm64   : Ok   aarch64-linux-gnu-gcc (Debian 14.1.0-5) 14.1.0  flex 2.6.4
  BUILD_TARBALL_HEAD=d31a974f6edc576f84c35be9526fec549a3b3520
  $
  $ git log --oneline -1 d31a974f6edc576f84c35be9526fec549a3b3520
  d31a974f6edc576f (HEAD -> perf-tools-next) perf MANIFEST: Add arch/*/include/uapi/asm/bpf_perf_event.h to the perf tarball
  $

That was previously failing:

  perfbuilder@number:~$ grep debian:experimental-x-arm64 dm.log.old/summary
  19     4.80 debian:experimental-x-arm64   : FAIL gcc version 14.1.0 (Debian 14.1.0-5)
  $
  perfbuilder@number:~$ grep -B6 'Error 1' dm.log.old/debian:experimental-x-arm64

README 

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 reStructuredText 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.
