svn commit: r252653 - head/sys/vm

[Neel Natu]

Author: neel

New Revision: 252653
URL: http://svnweb.freebsd.org/changeset/base/252653

Log:
  vm_phys_fictitious_reg_range() was losing the 'memattr' because it would be
  reset by pmap_page_init() right after being initialized in vm_page_initfake().
  
  The statement above is with reference to the amd64 implementation of
  pmap_page_init().
  
  Fix this by calling 'pmap_page_init()' in 'vm_page_initfake()' before changing
  the 'memattr'.
