I like this a lot, it gives me some hope that we can eventually
do the same for the remaining ARMv5 platforms that are
not multiplatform yet (s3c24xx, ks8695, w90x900, lpc32xx,
omap1, ep93xx, and maybe even the xscale based ones).

I have done a lot of randconfig testing with this patch appled now
and not found any issues, great work!
