Author: marius Date: Sun Jul 22 14:33:04 2012 New Revision: 238690 URL: http://svn.freebsd.org/changeset/base/238690 Log: MFC: r238621 Revert the use of BUS_DMA_ALLOCNOW when creating the DMA tag for user data introduced in r236061 (MFC'ed to stable/8 in r237187). Using that flag doesn't make that much sense on this case as the DMA maps using it are also created during sym_pci_attach(). Moreover, due to the maxsegsz parameter used, doing so may exhaust the bounce pages pool on architectures requiring bounce pages. [1] While at it, use a slightly more appropriate maxsegsz parameter.
