For hierarchical output, each entries should be sorted in their

The hierarchy output mode is to group entries for each level so that
user can see higher level picture more easily. It also helps to find
out which component is most costly. The output will look like below:
15.11% swapper
14.97% [kernel.vmlinux]
0.09% [libahc
The --hierarchy option is to show output in hierarchy mode. It extends
folding/unfolding in the TUI and GTK browsers to support sort items as
well as callchains. Users can toggle the items to see the performance
result at wanted level.
$ perf report --hierarchy --tui

headers with "/" as a separator.

* Makefile:
- globally use -mprofile-kernel in case it's configured
and available.
* arch/powerpc/Kconfig / kernel/trace/Kconfig:
- declare that ppc64le HAVE_MPROFILE_KERNEL and
HAVE_DYNAMIC_FTRACE_WITH_REGS, and use it.

arch/powerpc/Kconfi
Implement FTRACE_WITH_REGS for powerpc64, on ELF ABI v2.
Initial work started by Vojtech Pavlik, used with permission.
* arch/powerpc/kernel/entry_64.S:
- Implement an effective ftrace_caller that works from
within the kernel binary as well as from modules.
* arch/powerpc/kernel/ftra
Using -mprofile-kernel on early boot code not only confuses the
checker but is also useless, as the infrastructure is not yet in
place. Proceed like with -pg (remove it from CFLAGS), equally with
time.o and ftrace itself.
* arch/powerpc/kernel/Makefile:
- remove -mprofile-kernel from low lev

Convert ppc's arch_ftrace_update_code from its own function copy
to use the generic default functionality (without stop_machine --
our instructions are properly aligned and the replacements atomic ;)
With this we gain error checking and the much-needed function_trace_op
handling.

The gcc switch -mprofile-kernel, available for ppc64 on gcc > 4.8.5,
allows to call _mcount very early in the function, which low-level
ASM code and code patching functions need to consider.
Especially the link register and the parameter registers are still
alive and not yet saved into a new stack
At least POWER7/8 have MMUs that don't completely autoload;
a normal, recoverable memory fault might pass through these functions.
If a dynamic tracer function causes such a fault, any of these functions
being traced with -mprofile-kernel may cause an endless recursion.

gcc warns about the possibilty of accessing a property read from
