I have attached complete failure log. next-20220802 build was good.  

Git bisect points to following commit:
# git bisect bad
e50e9742515158aa30680b0a616bb5a8d049bf67 is the first bad commit
commit e50e9742515158aa30680b0a616bb5a8d049bf67

   Merge branch 'bitmap-for-next' of https://github.com/norov/linux.git

Not sure if this commit is actually the cause for build break.

I have attached .config file.
