John David Anglin 1b59ddfcf1 parisc: Use double word condition in 64bit CAS operation ...

The attached change fixes the condition used in the "sub" instruction.
A double word comparison is needed.  This fixes the 64-bit LWS CAS
operation on 64-bit kernels.

I can now enable 64-bit atomic support in GCC.
