H A D | Makefile | 6656920b Wed Aug 22 12:14:51 CDT 2007 Chris Zankel <chris@zankel.net> [XTENSA] Add support for cache-aliasing
Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.
