Yes, you need a very recent version of sparse. I was oging to hold off that sparse upgrade requirement for 5.9, but we had independent reasons to just say "gcc 4.9", and at that point the code that allowed old versions of sparse to work was entirely dead outside of sparse. Sparse is really easy to build and install as a regular user. Just do mkdir -p ~/src ; cd ~/src git clone git://git.kernel.org/pub/scm/devel/sparse/sparse.git cd sparse make && make install and it will install the sparse binaries in your ~/bin directory. No need to be root, it just works. Linus
