I'm confused: is this missing those three lines:

        movl    initial_gs(%rip),%eax
        movl    initial_gs+4(%rip),%edx
        wrmsr

as it is done in secondary_startup_64 ?

No, it is a leftover from before I moved the MSR write into
startup_64_setup_env(). I removed it, thanks for catching this.
