From 128e290b1e4204ac33b4cad7fc6189447f029311 Mon Sep 17 00:00:00 2001 From: Steve Kilbane Date: Mon, 21 Feb 2011 19:44:42 -0500 Subject: bfin: add support for new cacheflush syscall Newer gcc's will generate a call to cacheflush when updating jump tables, and that has to be done in kernel space (to avoid hardware anomalies). So make sure uClibc provides that symbol.
