John Baldwin 968950e5d1 - Rework pmap_map() to take advantage of direct-mapped segments on ... supported architectures such as the alpha. This allows us to save on kernel virtual address space, TLB entries, and (on the ia64) VHPT entries. pmap_map() now modifies the passed in virtual address on architectures that do not support direct-mapped segments to point to the next available virtual address. It also returns the actual address that the request was mapped to. - On the IA64 don't use a special zone of PV entries needed for early calls to pmap_kenter() during pmap_init(). This gets us in trouble because we end up trying to use the zone allocator before it is initialized. Instead, with the pmap_map() change, the number of needed PV entries is small enough that we can get by with a static pool that is used until pmap_init() is complete.
