+Subject: [PATCH 2/3] ppc64: rewrite get/set/swapcontext in assembly
+
+If getcontext makes any function call, which it does to call syscall, then
+it must spill its return address to the stack. After it returns to its
+caller, that return address can be clobbered. When setcontext is called
+to resume this saved context, the correct return address is not available.
