3.16.7-ckt18 -stable review patch. If anyone has any objections, please let me know. ------------------ From: John David Anglin <dave.anglin@xxxxxxxx> commit 1b59ddfcf1678de38a1f8ca9fb8ea5eebeff1843 upstream. 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.
