Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: LLVM/clang/eBPF: (Arnaldo Carvalho de Melo) - Allow passing options to llc in addition to to clang. Hardware tracing: (Jack Henschel) - Improve error message for PMU address filters, clarifying availability of that feature in hardware having hardware tracing such as Intel PT. Python interface: (Jiri Olsa) - Fix read_on_cpu() interface. ELF/DWARF libraries: (Jiri Olsa) - Fix handling of the combo compressed module file + decompressed associated debuginfo file. Build (Rasmus Villemoes) - Disable parallelism for 'make clean', avoiding multiple submakes deleting the same files and causing the build to fail on systems such as Yocto. Kernel ABI copies: (Arnaldo Carvalho de Melo) - Update tools's copy of x86's cpufeatures.h. - Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy'. Miscellaneous: (Steven Rostedt) - Change libtraceevent to SPDX License format. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
