Author: alc Date: Mon Jul 2 03:49:52 2012 New Revision: 237949 URL: http://svn.freebsd.org/changeset/base/237949 Log: MFC r226843 Eliminate vestiges of page coloring in VM_ALLOC_NOOBJ calls to vm_page_alloc(). While I'm here, for the sake of consistency, always specify the allocation class, such as VM_ALLOC_NORMAL, as the first of the flags.
