The section structure already contains sh_size, so just remove the extra 'len' member that requires extra mirroring and potential confusion.

Commit e31694e0a7a7 ("objtool: Don't make .altinstructions writable")
aligned objtool-created and kernel-created .altinstructions section
flags, but there remains a minor discrepency in their use of a section
entry size: objtool sets one while the kernel build does not.
While sh_entsize of sizeof(struct alt_instr) seems intuitive, this small
deviation can cause failures with external tooling (kpatch-build).
Fix this by creating new .altinstructions sections with sh_entsize of 0
and then later updating sec->sh_size as alternatives are added to the
section. An added benefit is avoiding the data descriptor and buffer
created by elf_create_section(), but previously unused by
elf_add_alternative().

Converting a special section's relocation reference to a symbol is
straightforward. No need for objtool to complain that it doesn't know
how to handle it. Just handle it.
This fixes the following warning:

The Topdown metrics events were added as 'perf stat' default events
since commit 42641d6f4d15e6db ("perf stat: Add Topdown metrics events as
default events").
However, the perf attr tests were not updated
accordingly.
The perf attr test fails on the platform which supports Topdown metrics.
# perf test 17
17: Setup struct perf_event_attr :FAILED!
Add Topdown metrics events into perf attr test cases. Make them optional
since they are only available on newer platforms.

Picking the changes from:
09d23174402da0f1 ("ALSA: rawmidi: introduce SNDRV_RAWMIDI_IOCTL_USER_PVERSION")
Which entails no changes in the tooling side as it doesn't introduce new
SNDRV_PCM_IOCTL_ ioctls.
