New Revision: 358718
URL: https://svnweb.freebsd.org/changeset/base/358718

Log:
  Remove dead code from the powerpc uma_small_alloc().
  
  32-bit Book-E doesn't set UMA_MD_SMALL_ALLOC, and 32-bit OEA platforms
  have a 32-bit vm_paddr_t.  Moreover, this code was wrong in that it
  leaked the page if the check failed.
