[PATCH] const vs. __attribute__((const)) confusion
From: "H. Peter Anvin" <hpa@zytor.com>
Declaring a function to return a const scalar value is pretty meaningless.
These functions are really trying to say that they don't alter any external
state.
Fix that up by using __attribute__((const)), if the compiler supports that.
