Re: Modules not working (missing uvmexp_pagesize)
The code intention looks like:
- PAGE_SIZE is defined by CPU type (oea, ibm4xx, ...) on powerpc
- But powerpc modules don't know the PAGE_SIZE before loaded
(powerpc/include/vmparam.h #ifdef _MODULE ...)
I guess that powerpc have to have the uvmexp_pagesize as a variable
(as sparcs do) to share single powerpc modules. I.e., PAGE_SIZE
should not be statically defined when MODULAR.
