I need to get rid of -mregparm=3 on gcc's command line. It
is completely incompatible with the standard calling conventions
used in all our assembly-language files in our drivers. We make
very high-speed number-crunching drivers that munge high-speed
data into images. We need to do that in assembly as we have
always done.
