src/sys/uvm: uvm_extern.h uvm_fault.c uvm_km.c uvm_page.c
Add better color matching selecting free pages. KM pages will now allocated
so that VA and PA have the same color. On a page fault, choose a physical
page that has the same color as the virtual address.
When allocating kernel memory pages, allow the MD to specify a preferred
VM_FREELIST from which to choose pages. For machines with large amounts
of memory (> 4GB), all kernel memory to come from <4GB to reduce the amount
of bounce buffering needed with 32bit DMA devices.
