Subject: [GIT PULL 0/2] perf tools changes for v6.4: Disable BPF based features in the default build

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Hi Linus,

	I did further tests and realised I made a mistake in trying to
make this the default now, we need to polish it further before this
becomes acceptable for a default build.

	This is on top of the previous two requests.

	I apologize for wasting your time,

- Arnaldo

  Revert "perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL" (2023-05-06 18:07:37 -0300)

----------------------------------------------------------------
Disable building BPF based features by default for v6.4.

We need to better polish building with BPF skels, so revert back to
making it an experimental feature that has to be explicitely enabled
using BUILD_BPF_SKEL=1.
