From 59f0cb0fddc14ffc6676ae62e911f8115ebc8ccf Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 27 Oct 2008 11:24:09 +0000 Subject: [ARM] remove memzero() As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero().
