Author: nwhitehorn Date: Thu Apr 1 13:21:04 2010 New Revision: 206041 URL: http://svn.freebsd.org/changeset/base/206041 Log: MFC r205163: Fix two small bugs. The PowerPC 970 does not support non-coherent memory access, and reflects this by autonomously writing LPTE_M into PTE entries. As such, we should not panic if LPTE_M changes by itself. While here, fix a harmless typo in moea64_sync_icache().
