-Subject: [PATCH gnumach 4/4] i386: specialize `copyinmsg' and `copyoutmsg'
-
-Previously, `copyinmsg' was the same function as `copyin'.  The former
-is for messages, and the size of messages is a multiple of four.
-Likewise for `copyoutmsg'.
-
-Provide a specialized version of both functions.  This shaves off a
-couple of instructions and improves our IPC performance.
-
-* i386/i386/locore.S (copyinmsg): New function.
-(copyoutmsg): New function.
