For lbr-as-callgraph we need to see the line number in the history,
because many LBR entries can be in a single function, and just
showing the same function name many times is not useful.
When the history code is configured to sort by address, also try to
resolve the address to a file:srcline and display this in the browser.
If that doesn't work still display the address.
This can be also useful without LBRs for understanding which call in a large
function (or in which inlined function) called something else.

If first level callchain has more than single path like when -g caller

Currently perf report on TUI doesn't print percent for first-level
callchain entry.
I guess it (wrongly) assumes that there's only a single callchain in the
first level.
This patch fixes it by handling the first level callchains same as
others - if it's not 100% it should print the percent value.
Also it'll affect other callchains in the other way around - if it's
100% (single callchain) it should not print the percentage.

Tests can set options that override the default ones. But if a test
tries to undefine a default option, it is simply ignored and the
default option stays as is.
For example, if you want to have a test that defines no MIN_CONFIG
then the test should be able to do that with:
TEST_START
MIN_CONFIG =
Which should make MIN_CONFIG not defined for that test. But the way
the code currently works, undefined options in tests are dropped.
This is because the NULL options are evaluated during the reading of
the config file and since one can disable default options in the default
section with this method, it is evaluated there (the option turns to a
undef). But undef options in the test section mean to use the default
option.
To fix this, keep the empty string in the option during the reading
of the config file, and then evaluate it when running the test. This
will allow tests to null out default options.

Commit 6071c22e1755 "ktest: Rewrite the config-bisect to actually work"
fixed the config-bisect to work nicely but in doing so it broke
make_min_config by changing the way assign_configs works.
The assign_configs function now adds the config to the hash even if
it is disabled, but changes the hash value to be that of the
line "# CONFIG_FOO is not set". Unfortunately, the make_min_config
test only checks to see if the config is removed. It now needs to
check if the config is in the hash and not set to be disabled.

Events may still be ordered even if there are no timestamps e.g. if the
data is recorded per-thread.
Also synthesized COMM events have a timestamp of zero.
Consequently it is better to keep comm entries even if they have a
timestamp of zero.
However, when a struct thread is created the command string is not known
and a comm entry with a string of the form ":<tid>" is used.
In that case thread->comm_set is false and the comm entry should be
overridden.

With srcline key/sort'ing it's useful to have line numbers in the
annotate window. This patch implements this.
Use objdump -l to request the line numbers and save them in the line
structure. Then the browser displays them for source lines.
The line numbers are not displayed by default, but can be toggled on
with 'k'
There is one unfortunate problem with this setup. For lines not
containing source and which are outside functions objdump -l reports
line numbers off by a few: it always reports the first line number in
the next function even for lines that are outside the function.
I haven't found a nice way to detect/correct this. Probably objdump has
to be fixed.
See https://sourceware.org/bugzilla/show_bug.cgi?id=16433
The line numbers are still useful even with these problems, as most are
correct and the ones which are not are nearby.
v2: Fix help text. Handle (discriminator...) output in objdump.
Left align the line numbers.

Patch "perf tools: Fix build-id matching on vmlinux" breaks annotation
with kcore. The problem is that symbol__annotate() first gets the
filename based on the build-id which was previously not set.
This patch provides a quick fix, however there should probably be only
one way to determine the filename. e.g. symbol__annotate() should use
the same way as dso__data_fd().

The minimal ELF loader should not return 1 when it manages to read the
vmlinux build-id, it should instead return 0, meaning that it hasn't
loaded any symbols, since it doesn't parses ELF at all.
That way, the main symbol.c routines will understand that it is
necessary to continue looking for a file with symbols, and when no
libelf is linked, that means it will eventually try kallsyms.

Add kselftest framework for tests to use. This is a light

results. Tests can use these interfaces to report pass, and
fail cases as well as when failure is due to configuration
problems such as missing modules, or when a test that is should
fail, fails as expected, and a test that should fail, passes.
The framework uses POSIX standard return codes for reporting
results to address the needs of users that want to run the kernel
selftests from their user-space test suites and want to know why a
test failed. In addition, the framework includes interfaces to use
to report test statistics on number of tests passed and failed.

The while loop in sock_fanout_read_ring() checks mmap region
bounds after access, causing it to segfault. Fix it to check
count before accessing header->tp_status. This problem can be
reproduced consistently when the test in run as follows:
make -C tools/testing/selftests TARGETS=net run_tests
or
make run_tests from tools/testing/selftests
or
make run_test from tools/testing/selftests/net

All tools/hv daemons do mandatory daemon() on startup. However, no pidfile
is created, this make it difficult for an init system to track such daemons.
Modern linux distros use systemd as their init system. It can handle the
daemonizing by itself, however, it requires a daemon to stay in foreground
for that. Some distros already carry distro-specific patch for hv tools
which switches off daemon().
Introduce -n/--no-daemon option for all 3 daemons in hv/tools. Parse options
with getopt() to make this part easily expandable.

If a partition appears mounted more than once in /proc/mounts, vss_do_freeze()
succeeds only for the first time and gets EBUSY (on freeze) or EINVAL (on
thaw) for the second time. The patch ignores these to make the backup feature
work.
Also improved the error handling in case a freeze operation fails.

The libtraceevent library's main handle 'struct pevent' holds pointers
of every event that was added to it via functions:
pevent_parse_format
pevent_parse_event
We can't release struct event_format (call pevent_free_format)
separately, because that breaks that pointers array mentioned above and
another add_event call could end up with segfault.
All added events are released within the handle cleanup in pevent_free.

We don't need to maintain cache of 'struct event_format' objects.
Currently the 'struct perf_evsel' holds this reference already.
Adding events_defined bitmap to keep track of defined events, which is
much cheaper than array of pointers.
