commit d3c61619568c88d48eccd5e74b4f84faa1440652 upstream.

Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")

That commit is in 4.19, not 4.14. So are you SURE this is ok for 4.14 and older kernels?

raised the minimum GCC version to 4.6. Old mcount is only required for GCC versions older than 4.4.0. Hence old mcount support can be dropped too.

And as I asked on the 4.19 submission of this patch, what does this have to do with clang?

thanks,
