Modified files:
sys/uvm : uvm_extern.h uvm_page.c uvm_pmemrange.c
Log message:
Move the uvm reserve enforcement from uvm_pagealloc to pmemrange.
More and more things are allocating outside of uvm_pagealloc these days making
it easy for something like the buffer cache to eat your last page with no
repercussions (other than a hung machine, of course).
ok ariane@ also ok ariane@ again after I spotted and fixed a possible underflow
problem in the calculation.
