Sadly, this fails to compile on sparc, because PAGE_SIZE isn't a constant,
but uvmexp.pagesize - which cpp doesn't know what to do with. (Similarly,
I have no idea what the right thing to do for this section of code is.)

FYI, the error produced is
src/sys/uvm/uvm_glue.c:354:37: error: token "." is not valid in preprocessor expressions
