    The means of finding ranges of free pages was changed for · f96e8a0b
    Doug Moore authored
    vm_reserv_break in r348484, and there was found to improve performance
    minutely and reduce code size. This change applies a similar change to
    vm_reserv_reclaim_config, expecting similar benefits. This change also
    allows quick rejection of page ranges that are unsuitable on account
    of alignment or boundary issues, where those issues are processed a
    page at a time in the current implementation.  For contrived test
    cases, this can make finding a reservation satisfying a major
    alignment requirement around 30 times faster.
