SVN rev 195940 on 2009-07-29 08:49:58Z by kib
As was done in r195820 for amd64, use clflush for flushing cache lines
when memory page caching attributes changed, and CPU does not support
self-snoop, but implemented clflush, for i386.
Take care of possible mappings of the page by sf buffer by utilizing
the mapping for clflush, otherwise map the page transiently. Amd64
used direct map.
