[PATCH] Make CONFIG_REGPARM enabled by default 



Make CONFIG_REGPARM enabled by default.  It's a noticable win both for size
and for performance, and gcc[34] handles it correctly.

	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.
