[PATCH 0/2] linux-yocto: v5.4 and v5.5 -prep

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Hi all,

As part of the v5.4 LTS reference kernel work, and v5.5 prep I ran into
a perf build failure with v5.5+.

Rather than sit on the issues that I find with v5.4 and v5.5, I'll send
patches as I go along. With these tweaks, I'm building and booting
v5.5 on linux-yocto-dev.

Cheers,

Bruce

[PATCH 2/2] perf: fix build for v5.5+

[bruce.ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

In kernel 5.5+ there are python3 scripts that explicitly use
/usr/bin/python3 as the interpreter. That will find the host
python and produce undefined results.

We add that interpreter path to our substitutions to ensure
that our sysroot variant is used.
