- Move non-TUI specific annotation routines out of the TUI browser so
that it can be used in other UIs, and to demonstrate that introduce
a 'perf annotate --stdio2' option that will apply those formatting
routines to provide a non-interactive annotation mode (Arnaldo Carvalho de Melo)
- Add 'P' hotkey to the annotation TUI, so dump the current annotated
symbol to a file, easing report thru e-mail, by getting rid of the
spaces + right hand side scrollbar chars (Arnaldo Carvalho de Melo)
- Support --ignore-vmlinux to 'perf report' and 'perf annotate', that
was already present in 'perf top', to use /proc/{kcore,kallsyms},
allowing to see what is in fact running (patched stuff, alternatives,
ftrace, etc), not the initial state of the kernel (vmlinux) (Arnaldo Carvalho de Melo)
- Support 'jump' instructions to a different function, treating them
as 'call' instructions (Arnaldo Carvalho de Melo)
- Fix some jump artifacts when using vmlinux + ASM functions, where
the ELF symtab for instance, for entry_SYSCALL_64 includes that and
what comes after the 'syscall_return_via_sysret' label, but the
objdump -dS prints the jump targets + offsets using the
syscall_return_via_sysret address, which was confusing 'perf annotate'.
See the cset comments for further info (Arnaldo Carvalho de Melo)
- Report error from dwfl_attach_state() in the unwind code (Martin Vuille)
- Reference Py_None before returning it in the python extension (Petr Machata)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
