This provides a place to document the assumptions made by the assembly language functions about their arguments (e.g., how they handle length values of 0, less than some value, not multiples of some value, etc.). Not all the assembly language files are tackled yet - just some of the x86 files pending changes related to kernel_fpu_begin/end.
