This is caused due to these two commits. Let us drop them.

I reverted those two and did a make, then I see another build error:

   CC       util/genelf.o

util/genelf.h:5:10: fatal error: linux/math.h: No such file or directory

^^^ this commit is causing this.

Earlier we have seen similar errors on 5.15.136, some notes on what is 
causing this:
https://lore.kernel.org/stable/fb1ce733-d612-4fa3-a1e4-716545625822@oracle.com/

I think we should drop these three perf/ commits.

Thanks,
