Alan Cox 04a18977c8 Define every architecture as either VM_PHYSSEG_DENSE or ... VM_PHYSSEG_SPARSE depending on whether the physical address space is densely or sparsely populated with memory. The effect of this definition is to determine which of two implementations of vm_page_array and PHYS_TO_VM_PAGE() is used. The legacy implementation is obtained by defining VM_PHYSSEG_DENSE, and a new implementation that trades off time for space is obtained by defining VM_PHYSSEG_SPARSE. For now, all architectures except for ia64 and sparc64 define VM_PHYSSEG_DENSE. Defining VM_PHYSSEG_SPARSE on ia64 allows the entirety of my Itanium 2's memory to be used. Previously, only the first 1 GB could be used. Defining VM_PHYSSEG_SPARSE on sparc64 allows USIIIi-based systems to boot without crashing. This change is a combination of Nathan Whitehorn's patch and my own work in perforce. Discussed with: kmacy, marius, Nathan Whitehorn PR: 112194		2007-05-05 19:50:28 +00:00
