Thanks for all your testings and suggestions.
For me it was easier to apply these 3 patches on top of my custom
patchset to see what impact Peter's patchset.
AFAICS you did a 5 times x86-64 defconfig with dropped pagecache and `make -j9`?
I run my "normal" workflow(s) (and build-script) for easier comparison
on my side.
Big thank-you for testing with LLVM/Clang v11.x - twice as slow as with GCC :-(.
A selfmade ThinLTO+PGO optimized LLVM tooolchain v11.x/v12-rcX/v13-git
is here as fast as Debian's GCC-v10.2.1 to build a Linux-kernel -
approx. 03:30 [hh:mm] - full adapted Debian v5.10.y kernel-config.
Does your distribution offer LLVM/Clang v12.0.0-rc3 (released this
week) binaries?
