until_counter_is() currently takes as an argument a number and the
condition holds when the current counter value is >= that number. Make the
function more generic by taking a partial expression instead of just the
number.

The function tc_rule_stats_get() fetches a given statistic of a TC rule
given the rule preference. Another common way to reference a rule is using
its handle. Introduce a dual to the aforementioned function that gets a

The dso->kernel value is now set to everything that is in
machine->kmaps, but that was being used to decide if vmlinux lookup is
needed, which ended up making that lookup be made for kernel modules,
that now have dso->kernel set, leading to these kinds of warnings when
running on a machine with compressed kernel modules, like fedora:31:

With bpf_link abstraction supported by kernel explicitly, add
pinning/unpinning API for links. Also allow to create (open) bpf_link from BPF
FS file.
This API allows to have an "ephemeral" FD-based BPF links (like raw tracepoint
or fexit/freplace attachments) surviving user process exit, by pinning them in
a BPF FS, which is an important use case for long-running BPF programs.
As part of this, expose underlying FD for bpf_link. While legacy bpf_link's
might not have a FD associated with them (which will be expressed as
a bpf_link with fd=-1), kernel's abstraction is based around FD-based usage,
so match it closely. This, subsequently, allows to have a generic
pinning/unpinning API for generalized bpf_link. For some types of bpf_links
kernel might not support pinning, in which case bpf_link__pin() will return
error.
With FD being part of generic bpf_link, also get rid of bpf_link_fd in favor
of using vanialla bpf_link.

Add detection of vmlinux.h to bpf_tracing.h header for PT_REGS macro.
Currently, BPF applications have to define __KERNEL__ symbol to use correct
definition of struct pt_regs on x86 arch. This is due to different field names
under internal kernel vs UAPI conditions. To make this more transparent for
users, detect vmlinux.h by checking __VMLINUX_H__ symbol.

libbpf modes with dependency on kernel headers. This will make it possible to
write helper macro/functions, agnostic to exact BPF program set up.

It is possible to return a pointer to a local variable when looking up
the architecture name for the running system and no normalization is
done on that value, i.e. we may end up returning the uts.machine local
variable.
While this doesn't happen on most arches, as normalization takes place,
lets fix this by making that a static variable and optimize it a bit by
not always running uname(), only the first time.

The test checks that packets are trapped when they should egress a
router interface (RIF) that has become disabled. This is a temporary
state in a RIF's deletion sequence.
Currently, the test deletes the RIF by flushing all the IP addresses
configured on the associated netdev (br0). However, this is racy, as
this also flushes all the routes pointing to the netdev and if the
routes are deleted from the device before the RIF is disabled, then no
packets will try to egress the disabled RIF and the trap will not be
triggered.
Instead, trigger the deletion of the RIF by unlinking the mlxsw port
from the bridge that is backing the RIF. Unlike before, this will not
cause the kernel to delete the routes pointing to the bridge.
Note that due to current mlxsw locking scheme the RIF is always deleted
first, but this is going to change.

This tests that below the queue minimum length, there is no dropping /
marking, and above max, everything is dropped / marked.
The test is structured as a core file with topology and test code, and
three wrappers: one for RED used as a root Qdisc, and two for
testing (W)RED under PRIO and ETS.

The radix tree doesn't use alignment, so the argument was ignored.
The maple tree needs its nodes to be aligned, so we need to pay attention
to the alignment argument. Also change the types of 'size' and 'align'
to unsigned int to match commit f4957d5bd0916.

While rendering annotate browser from perf report tui, we keep track
of total number of lines(asm + source) in annotation->nr_entries and
total number of asm lines in annotation->nr_asm_entries. But we don't
reset them before starting. Thus if user annotates same function
multiple times, we restart incrementing these fields with old values.
This causes a segfault when user tries to toggle source code after
annotating same function multiple times. Fix it.

We are allocating disasm_line object in annotation_line__new() instead
of disasm_line__new(). Similarly annotation_line__delete() is actually
freeing disasm_line object as well. This complexity is because of
privsize. But we don't need privsize anymore so get rid of privsize and
simplify disasm_line allocation and freeing code.

perf config annotate options says it works only with TUI, which is wrong.
Most of the TUI options are applicable to stdio2 as well. So remove that
generic line and add individual line with each option stating which
browsers supports that option. Also, annotate.show_nr_samples config is
missing in Documentation. Describe it.

For all the perf-config options that can also be set from command line
option, the preference is given to command line version in case of any
conflict. But that's opposite in case of perf annotate. i.e. the more
preference is given to default option rather than command line option.
Fix it.
Before:
$ ./perf config
annotate.show_nr_samples=false
$ ./perf annotate shash --show-nr-samples
