svn commit: r233547 - head/sys/ofed/include/linux

[John Baldwin]

Author: jhb
Date: Tue Mar 27 14:24:29 2012
New Revision: 233547
URL: http://svn.freebsd.org/changeset/base/233547

Log:
  Use VM_MEMATTR_UNCACHEABLE instead of VM_MEMATTR_UNCACHED for UC mappings.
  VM_MEMATTR_UNCACHED is actually the x86-specific UC- mode (where a WC
  MTRR can override the PAT setting).
