Won't setting PAGE_SIZE to 16k break some existing userlands (o32)? I use a 4k PAGE_SIZE because the last few times I've tried 16k or 64k, init won't load (SIGSEGVs or such, which panicks the kernel). -- Joshua Kinard Gentoo/MIPS kumba@xxxxxxxxxx 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
