We have a tools/build/feature/test-all.c that has the most common set of
features that perf uses and are expected to have its development files
available when building perf.
When we made libwunwind opt-in we forgot to remove them from the list of
features that are assumed to be available when test-all.c builds, remove
them.
Before this patch:
$ rm -rf /tmp/b ; mkdir /tmp/b ; make -C tools/perf O=/tmp/b feature-dump ; grep feature-libunwind-aarch64= /tmp/b/FEATURE-DUMP
feature-libunwind-aarch64=1
$
Even tho this not being test built and those header files being
available:
$ head -5 tools/build/feature/test-libunwind-aarch64.c
// SPDX-License-Identifier: GPL-2.0
#include <libunwind-aarch64.h>
#include <stdlib.h>
extern int UNW_OBJ(dwarf_search_unwind_table) (unw_addr_space_t as,
$
After this patch:
$ grep feature-libunwind- /tmp/b/FEATURE-DUMP
$
Now an audit on what is being enabled when test-all.c builds will be
performed.

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.
