Eliminate vm_phys_bootstrap_alloc(). It was a failed attempt at
eliminating duplicated code in the various pmap implementations.
Micro-optimize vm_phys_free_pages().
Introduce vm_phys_free_contig(). It is fast routine for freeing an
arbitrary number of physically contiguous pages. In particular, it
doesn't require the number of pages to be a power of two.
Use "u_long" instead of "unsigned long".
Bruce Evans (bde@) has convinced me that the "boundary" parameters
to kmem_alloc_contig(), vm_phys_alloc_contig(), and
vm_reserv_reclaim_contig() should be of type "vm_paddr_t" and not
"u_long". Make this change.
