Author: jhb Date: Thu Apr 12 13:47:23 2012 New Revision: 234180 URL: http://svn.freebsd.org/changeset/base/234180 Log: MFC 233670,233671: - Use VM_MEMATTR_UNCACHEABLE for the constant for UC memory rather than VM_MEMATTR_UNCACHED on mips. - Rename VM_MEMATTR_UNCACHED to VM_MEMATTR_WEAK_UNCACHEABLE on x86 to be less ambiguous and more clearly identify what it means. An alias from VM_MEMATTR_WEAK_UNCACHEABLE to VM_MEMATTR_WEAK_UNCACHED remains on x86 to preserve the KPI. - Remove the VM_MEMATTR_UNCACHED alias from powerpc.
