+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
