Are there any facilities for allocating physical page frames witout
mapping them in? Since I will only be accessing the pages though physical
addresses, I don't want to maintain the info about any virtual mappings
just so I can free them later on.
As far as I can see, you can allocate a virtual page using
vm_page_alloc(), or you can frob the page free list yourself, which is
breaks modularity. Any other ideas?
