Hello,

In src/sys/lib/libkern/arch/arm/memmove.S of the netbsd-3 branch 
and the netbsd-2 branch, it seems that a part of lsl and lsr have changed 
mutually places.
When the following both conditions are satisfied, this problem happens:

  * The source address(A) is greater than the destination address(B).
  * remainder of (A-B)/4 is 1.

I made the following patch that fixes this problem. Is this correct?
