thompsa 2009-06-18 20:42:37 UTC FreeBSD src repository Modified files: sys/arm/arm pmap.c sys/arm/include pmap.h Log: SVN rev 194459 on 2009-06-18 20:42:37Z by thompsa Track the kernel mapping of a physical page by a new entry in vm_page structure. When the page is shared, the kernel mapping becomes a special type of managed page to force the cache off the page mappings. This is needed to avoid stale entries on all ARM VIVT caches, and VIPT caches with cache color issue.
