Author: nwhitehorn Date: Thu Dec 2 18:01:18 2010 New Revision: 216129 URL: http://svn.freebsd.org/changeset/base/216129 Log: Set the cache hint bit in our IOPTEs so that they are not evicted by hardware. This prevents I/O hangs now that more of the address space is accessible to the EHCI driver. While here, remove some irrelevant DMA tag restrictions.
