From 6c31d55f755ff2bc1f7dc3b45c500032fe90aff8 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 28 Apr 2009 08:04:10 -0700 Subject: [PATCH] gianfar: Use memset instead of cacheable_memzero cacheable_memzero() is completely overkill for the clearing out the FCB block which is only 8-bytes. The compiler should easily optimize this with memset. Additionally, cacheable_memzero() only exists on ppc32 and thus breaks builds of gianfar on ppc64.
