procps is probably the trigger of this.  Me and some other Gentoo/MIPS 
devs/users got into a bit of a heated discussion w/ the procps 
maintainer, who didn't quite like the fact that A) We don't use 
"sanitized" kernel headers B) PAGE_SIZE was hidden on MIPS and C) 
"properly sanitized" headers would provide PAGE_SIZE.  We opted instead 
for a patch to procps that used sysconf(_SC_PAGESIZE) to fetch the 
value, and I guess this just didn't rub the right way w/ the maintainer. 
 Got me.
I can post the discussions for those interested (or just looking for 
amusement), and anyone curious enough can look at proc/procps.h in the 
procps tree for a rather amusing (IMHO) comment on MIPS at the top of 
the source.
