From a483a167bc8d808145ca1224a2c238cda90aa60c Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Fri, 21 Aug 2009 23:05:20 -0500 Subject: [PATCH] Standardize mem_malloc_init() implementation This lays the groundwork to allow architectures to share a common mem_malloc_init(). Note that the x86 implementation was not modified as it did not fit the mold of all other architectures.
