CVS commit: src/sys/uvm

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Wed Apr  9 16:34:11 UTC 2003

Modified Files:
        src/sys/uvm: uvm_page.c uvm_param.h

Log Message:
Tweak the way the pagesize-related variables are set:
* Remove DEFAULT_PAGE_SIZE.  We don't use PAGE_SIZE the way Mach did.
* In uvm_setpagesize(), if we are called with uvmexp.pagesize == 0,
  then assert that PAGE_SIZE != 0 (i.e. a constant), and set uvmexp.pagesize
  accordingly.
* Provide defaults for MIN_PAGE_SIZE and MAX_PAGE_SIZE if not defined
  by <machine/vmparam.h>.  If PAGE_SIZE is not a constant, MIN_PAGE_SIZE
  and MAX_PAGE_SIZE must be provided.
* If MIN_PAGE_SIZE and MAX_PAGE_SIZE are not equal (i.e. PAGE_SIZE may
  not be a constant in all configurations), then ensure that PAGE_SIZE
  and friends expand to variable references for LKMs.
