+Subject: parisc: fix cache-flushing
+
+From: Helge Deller <deller@gmx.de>
+
+commit 57737c49dd72c96cfbcd4f66559f3ffc399aeb4f upstream.
+
+This commit:
+f8dae00684d678afa13041ef170cecfd1297ed40: parisc: Ensure full cache coherency for kmap/kunmap
+caused negative caching side-effects, e.g. hanging processes with expect and
+too many inequivalent alias messages from flush_dcache_page() on Debian 5 systems.
+
+This patch now partly reverts it and has been in production use on our debian buildd
+makeservers since a week without any major problems.

+Subject: parisc/sti_console: prefer Linux fonts over built-in ROM fonts
+
+From: Helge Deller <deller@gmx.de>
+
+commit 8a10bc9d27ceb084b0d8be621a033a475eb9fdfd upstream.
+
+The built-in ROM fonts lack many necessary ASCII characters, which is
+why it makes sens to prefer the Linux fonts instead if they are
+available. This makes consoles on STI graphics cards which are not
+supported by the stifb driver (e.g. Visualize FXe) looks much nicer.
