Peter Zijlstra d5d797dcbd x86/usercopy: Remove .fixup usage 
Typically usercopy does whole word copies followed by a number of byte
copies to finish the tail. This means that on exception it needs to
compute the remaining length as: words*sizeof(long) + bytes.

Create a new extable handler to do just this.
