+Upstream-Status: Pending
+
+Remove the `q' suffix on x86-64 atomic instructions.
+
+We don't need the `q' suffix on x86_64 atomic instructions for AO_t,
+which is defined as "unsigned long".  "unsigned long" is 32bit for x32
+and 64bit for x86-64. The register operand in x86-64 atomic instructions
+is sufficient to properly determine the register size.
