- Compile the kernel with -mregparm=3. This uses a different ABI
- and passes the first three arguments of a function call in registers.
+ Compile the kernel with -mregparm=3. This instructs gcc to use
+ a more efficient function call ABI which passes the first three
+ arguments of a function call via registers, which results in denser
+ and faster code.
+
+ If this option is disabled, then the default ABI of passing
+ arguments via the stack is used.

+ If unsure, say Y.
