svn commit: r366944 - head/sys/arm64/arm64

[Alan Cox]

New Revision: 366944
URL: https://svnweb.freebsd.org/changeset/base/366944

Log:
  Micro-optimize uma_small_alloc().  Replace bzero(..., PAGE_SIZE) by
  pagezero().  Ultimately, they use the same method for bulk zeroing, but
  the generality of bzero() requires size and alignment checks that
  pagezero() does not.
  
  Eliminate an unnecessary #include.
