- Rename VM_MEMATTR_UNCACHED to VM_MEMATTR_WEAK_UNCACHEABLE on x86 to
be less ambiguous and more clearly identify what it means. This attribute is what Intel refers to as UC-, and it's only difference relative to normal UC memory is that a WC MTRR will override a UC- PAT entry causing the memory to be treated as WC, whereas a UC PAT entry will always override the MTRR. - Remove the VM_MEMATTR_UNCACHED alias from powerpc.
