From eacb1962d4594b9d382b40acd73a9c9492718f74 Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Sat, 4 Mar 2006 13:15:40 +0100 Subject: [PATCH] [PATCH] powerpc: correct cacheflush loop in zImage Correct the loop for cacheflush. No idea where I copied the code from, but the original does not work correct. Maybe the flush is not needed.
