The pager will result stdout in full buffering mode instead of line

hists__find_annotations() allows to move to next or previous symbols for
annotation using the arrow keys. But TUI annotate_browser__run() uses
the RIGHT key as ENTER to handle jump/call instructions. That makes the
navigation to the next function impossible.
I'd like to change it back to move the next symbol but I'm afraid if
some users get confused. So I added a new pair of keys to handle that.

When the source argument of the "mov" instruction looks like below, it
didn't parse the whole operand and just stopped at the first comma.
mov (%rbx,%rax,1),%rcx
Fix it by checking the parentheses and move it to the closing one.

I found that the "decq", "incq", "testq", "tzcnt" instructions didn't
parse the operands properly. Add them to the "x86__instructions" table
to fix the issue.

When building man pages from a Git checkout, we consistently set the
man page date based on when the input was last changed. Otherwise, it
defaults to the build time, which is not reproducible.
Allow the date to be set through the KBUILD_BUILD_TIMESTAMP variable,
as for timestamps in the kernel itself.

When building perf documentation with asciidoc, we use "git log" to
find the last commit date of each doc source and pass that to asciidoc
to use as the man page date.
When using asciidoctor, however, the current date is always used
instead. Defining perf_date like we do for asciidoc also doesn't
work because we're not using DocBook as an intermediate format.
The asciidoctor man page backend looks for the variable "docdate",
so set that instead.

Ids/events from a metric are turned into an event string and parsed;
setup_metric_events matches the id back to the parsed evsel. With
hybrid the same event may exist on both PMUs with the same name and be
being used by metrics at the same time. A metric on cpu_core therefore
shouldn't match against evsels on cpu_atom, or the metric will compute
the wrong value. Make the matching sensitive to the PMU being parsed.

Fix the metrics tma_memory_bound on alderlake cpu_core and
tma_microcode_sequencer on alderlake cpu_atom, where metrics had be
rewritten across PMUs. Fix MEM_BOUND_STALLS_AT_RET_CORRECTION which is
an aux metric but lacks a hash prefix. Add PMU prefixes for
cpu_core/cpu_atom events to avoid wildcard opening the events.

An event like "cpu/instructions/" typically parses due to there being
a sysfs event called instructions. On hybrid recursive parsing means
that the hardware event is encoded in the attribute, with the PMU
being placed in the high bits of the config:
'''
$ perf stat -vv -e 'cpu_core/cycles/' true
...
------------------------------------------------------------
perf_event_attr:
size 136
config 0x400000000
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
enable_on_exec 1
exclude_guest 1
------------------------------------------------------------
'''
Make this behavior the default by adding a new term type and token for
hardware events. The token gathers both the numeric config and the
parsed name, so that if the token appears like "cycles/name=cycles/"
then the token can be handled like a name. The numeric value isn't
sufficient to distinguish say "cpu-cycles" from "cycles".
Extend the parse-events test so that all current non-PMU hardware
parsing tests, also test with the PMU cpu - more than half the change.

Rather than limit the --cputype argument for "perf list" and "perf
stat" to hybrid PMUs of just cpu_atom and cpu_core, allow any PMU.
Note, that if cpu_atom isn't mounted but a filter of cpu_atom is
requested, then this will now fail. As such a filter would never
succeed, no events can come from that unmounted PMU, then this
behavior could never have been useful and failing is clearer.

Legacy raw events like r1a open as PERF_TYPE_RAW on non-hybrid systems
and on each hybrid PMU on hybrid systems. Rather than iterate hybrid
PMUs add a perf_pmu__supports_wildcard_numeric function that says when
a numeric event should be opened upon it. If the parsed event
specifies the type of the PMU then don't wildcard match PMUs, use the
specified PMU type.

alias with the PMU. Remove the now unnecessary hybrid logic.
Note, the alias output removes the event type descriptor, so:

It is inconsistent that "perf stat -e instructions-retired" wildcard
opens on all PMUs while legacy cache events like "perf stat -e
L1-dcache-load-miss" do not. A behavior introduced by hybrid is that a
legacy cache event like L1-dcache-load-miss should wildcard open on
all hybrid PMUs. Previously hybrid would call to is_event_supported
for each PMU, a failure of which results in the event not being
added. This isn't done in this case as the parser should just create
perf_event_attr and the later open should fail, or the counter give
"<not counted>". If this wants to be avoided then the PMU can be named
with the event.

Allow a legacy cache event to be both, for example,
"L1-dcache-load-miss" and "cpu/L1-dcache-load-miss/" by introducing a
new legacy cache term type.
The term type is processed in config_term_pmu, setting both the type in
perf_event_attr and the config.
The code to determine the config is factored out of
parse_events_add_cache and shared. If the PMU doesn't support legacy
events, currently just core/hybrid PMUs do, then the term is treated
like a PE_NAME term - as before.
If only terms are being parsed, such as for perf_pmu__new_alias, then
the PE_LEGACY_CACHE token is always parsed as PE_NAME.

The event parser needs to handle two special cases:
1) legacy events like L1-dcache-load-miss. These event names don't
appear in JSON or sysfs, and lookup tables are used for the config
value.
2) raw events where 'r0xead' is the same as 'read' unless the PMU has
an event called 'read' in which case the event has priority.
The previous parser to handle these cases would scan all PMUs for
components of event names. These components would then be used to
classify in the lexer whether the token should be part of a legacy
event, a raw event or an event. The grammar would handle legacy event
tokens or recombining the tokens back into a regular event name. The
code wasn't PMU specific and had issues around events like AMD's
branch-brs that would fail to parse as it expects brs to be a suffix
on a legacy event style name:
$ perf stat -e branch-brs true
event syntax error: 'branch-brs'
\___ parser error
This change removes processing all PMUs by using the lexer in the form
of a regular expression matcher. The lexer will return the token for
the longest matched sequence of characters, and in the event of a tie
the first. The legacy events are a fixed number of regular
expressions, and by matching these before a name token its possible to
generate an accurate legacy event token with everything else matching
as a name. Because of the lexer change the handling of hyphens in the
grammar can be removed as hyphens just become a part of the name.
To handle raw events and terms the parser is changed to defer trying
to evaluate whether something is a raw event until the PMU is known in
the grammar. Once the PMU is known, the events of the PMU can be
scanned for the 'read' style problem. A new term type is added for
these raw terms, used to enable deferring the evaluation.
While this change is large, it has stats of:
170 insertions(+), 436 deletions(-)
the bulk of the change is deleting the old approach. It isn't possible
to break apart the code added due to the dependencies on how the parts
of the parsing work.

Opening hardware names and a legacy cache event on a hybrid PMU opens
it on each PMU. Parsing and checking indexes fails, as the parsed
index is double the expected. Avoid checking the index by just
comparing the names immediately after the parse.
This change removes hard coded hybrid logic and removes assumptions
about the expansion of an event. On hybrid the PMUs may or may not
support an event and so using a distance isn't a consistent solution.

test__checkevent_config_cache checks the parsing of
"L1-dcache-misses/name=cachepmu/". Don't just check that the name is
set correctly, also validate the rest of the perf_event_attr for
L1-dcache-misses.

Rather than skip all tests in test__events_pmu if PMU cpu isn't
present, use the per-test valid test. This allows the running of
software PMU tests on hybrid and arm systems.

When building sign-file, the call to get the CFLAGS for libcrypto is
missing white-space between `pkg-config` and `--cflags`:
$(shell $(HOSTPKG_CONFIG)--cflags libcrypto 2> /dev/null)
Removing the redirection of stderr, we see:
$ make -C tools/testing/selftests/bpf sign-file
make: Entering directory '[...]/tools/testing/selftests/bpf'
make: pkg-config--cflags: No such file or directory
SIGN-FILE sign-file
make: Leaving directory '[...]/tools/testing/selftests/bpf'
Add the missing space.

dso->long_name if the dso->name starts with '[' or the dso is kcore, in
order to avoid special names such as [vdso], or mixing up kcore with
