When building in ClearLinux using 'make PYTHON=python3' with gcc 8.2.1
it fails with:

He also suggested the fix to properly check that the new size is below

When ordering events, we use preallocated buffers to store separate
events. Those buffers currently don't have their own struct, but since
they are basically an array of 'struct ordered_event' objects, we use
the first event to hold buffers data - list head, that holds all buffers
together:
struct ordered_events {
...
struct ordered_event *buffer;
...
};
struct ordered_event {
u64 timestamp;
u64 file_offset;
union perf_event *event;
struct list_head list;
};
This is quite convoluted and error prone as demonstrated by free-ing
issue discovered and fixed by Stephane in here [1].
This patch adds the 'struct ordered_events_buffer' object, that holds
the buffer data and frees it up properly.

Commit 1c5aae7710 ("perf machine: Create maps for x86 PTI entry
trampolines") revealed a problem with maps__find_symbol_by_name() that
resulted in probes not being found e.g.
$ sudo perf probe xsk_mmap
xsk_mmap is out of .text, skip it.
Probe point 'xsk_mmap' not found.
Error: Failed to add events.
maps__find_symbol_by_name() can optionally return the map of the found
symbol. It can get the map wrong because, in fact, the symbol is found
on the map's dso, not allowing for the possibility that the dso has more
than one map. Fix by always checking the map contains the symbol.

When we don't have the iputils-debuginfo package installed, i.e. when we
don't have the DWARF information needed to resolve ping's samples, we
end up failing this 'perf test' entry:
# perf test ping
62: probe libc's inet_pton & backtrace it with ping : Ok
# rpm -e iputils-debuginfo
# perf test ping
62: probe libc's inet_pton & backtrace it with ping : FAILED!
#
Fix it to accept "[unknown]" where the symbol + offset, when resolved,
is expected.
I think this will fail in the other arches as well, but since I can't
test now, I'm leaving s390x and ppc cases as-is.

Using a value returned from probe_read_str() to tell how many bytes to
copy using perf_event_output() has issues in some older kernels, like
4.17.17-100.fc27.x86_64, so separate the bounds checking done on how
many bytes to copy to a separate variable, so that the next patch has
only what is being done to make the test pass on older BPF validators.

Add default handler for non-jump instructions. This really only has an
effect on instructions that compute a PC-relative address, such as
'adrp,' as seen in these couple of examples:
BEFORE: adrp x0, ffff20000aa11000 <kallsyms_token_index+0xce000>
AFTER: adrp x0, kallsyms_token_index+0xce000
BEFORE: adrp x23, ffff20000ae94000 <__per_cpu_load>
AFTER: adrp x23, __per_cpu_load
The implementation is identical to that of s390, but with a slight
adjustment for objdump whitespace propagation (arm64 objdump puts spaces
after commas, whereas s390's presumably doesn't).
The mov__scnprintf() declaration is moved from s390's to arm64's
instructions.c because arm64's gets included before s390's.

Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff.
