The 2.5.19 copy routines use the movsl instruction. We found that when the
src or dst addresses are not aligned on 8 bytes, performance can be
improved
by using the integer registers instead of the movsl instruction. For
tcpip,
the src or dst addresses are often misaligned.
If the code is going to become so much larger, move the implementation
out of the header file and into arch/i386/lib/foo.S
It makes no sense to inline it anymore if it is going to be
implemented with so many instructions.
