This patch removes two unused macros: X86_VENDOR and X86_HARD_MATH
from the arch/x86/kernel/head_32.S. Also as CPUINFO_x86_vendor not
used anywhere, we can safely remove it from asm-offsets_32.c

This patch improves collection and setting of filters, allows --filter
be set to BPF placeholder events (which is a software dummy event).
perf_evsel__is_dummy(), perf_evsel__is_bpf_placeholder() and
perf_evsel__can_filter() are introduced for this.
Test result:

This patch adds a bpf_fd field to 'struct evsel' then introduces method

By introducing new rules in tools/perf/util/parse-events.[ly], this
patch enables 'perf record --event bpf_file.o' to select events by an
eBPF object file. It calls parse_events_load_bpf() to load that file,
which uses bpf__prepare_load() and finally calls bpf_object__open() for
the object files.
This patch introduces bpf__{un,}probe() functions to enable callers to
create kprobe points based on section names of BPF programs. It parses
the section names of each eBPF program and creates corresponding 'struct
perf_probe_event' structures. The parse_perf_probe_command() function is

On some hypervisors, virtio devices tend to generate spurious interrupts

which then causes an "irq %d: nobody cared" message, with irq being
