3 -- Compiling the kernel with -j for parallel makes is not completely safe
4 due to missing dependencies with offset.h. Usually it is safe when it
5 already exists, but not always.
7 Current hack is to rerun make depend manually when you change anything
8 that would touch offset.h (see arch/x86-64/tools/offset.c on what that is).
9 Do not use -j with depend.
