Ok to do as you suggested I had to restructure the mainline a bit. The 
Attached patch factors the common function of get/set/swapcontext.S into 
get/set/swapcontext-common.S with conditional compilation of FPU and VMX 
support. Then new implementations in powerpc32/fpu can #include the 
common code as needed to to support the function.

A separate patch will include the powerpc32/nofpu implementation for ports.
