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.
