PS1: 
Looks okay to me. Let's just wait some more time in case there are any other comments.

File src/cpu/x86/mp_init.c:

PS1, Line 998: run_serial
nit: If you flip the organization, you won't need the additional tab on if block.

if (!run_serial)
    return mp_run_on_aps(func, arg, 0, expire_us);

for (...) {
}

return 0;

To avoid the negative check, you can rename run_serial to run_parallel instead.

Assumption is that this call is made from BSP only.
