Hi Greg and others,

sorry for reporting this so late, but still...

this breaks build on older compilers, since it requires -mindirect-branch=thunk-inline -mindirect-branch-register even though retpoline support is disabled in kernel config.. is this expected?

What exact "older compilers" break here?

And does the same breakage happen in 4.18.6 or 4.19-rc?

thanks,

greg k-h
