I'd prefer to keep the config option so that people can diagnose compiler
and kernel bugs by disabling it.  This has proved useful in the past.

[-mm patch] always enable regparm on i386

[Adrian Bunk]

The patch below always enables regparm on i386 (with gcc >= 3.0).

With this patch, it should get a better testing coverage in -mm.

This patch should help to find bugs that show up with regparm enabled.

Compile the kernel with -mregparm=3. This uses an different ABI
and passes the first three arguments of a function call in registers.
