modpost: Skip .llvm.call-graph-profile section check
.llvm.call-graph-profile section is added by clang when the kernel is built with profiles (e.g. -fprofile-sample-use= or -fprofile-use=). Note that .llvm.call-graph-profile intentionally uses REL relocations to decrease the object size, for more details see https://reviews.llvm.org/D104080. The section contains edge information derived from text sections, so .llvm.call-graph-profile itself doesn't need more analysis as the text sections have been analyzed. This change fixes the kernel build with clang and a sample profile which currently fails with: "FATAL: modpost: Please add code to calculate addend for this architecture" Signed-off-by:Denis Nikitin <denik@chromium.org> Reviewed-by:
