-From: Wolfram Joost <dbox2@frokaschwei.de>
-Subject: [PATCH] fork_cacheflush
-
-On ASUS WL-500gP there are many unexpected "Segmentation fault"s that
-seem to be caused by a kernel. They can be avoided by:
-1) Disabling highpage
-2) Using flush_cache_mm in flush_cache_dup_mm
-
-For details see OpenWrt ticket #2035 https://dev.openwrt.org/ticket/2035
