From 78438b36011d8ef7d28ef63a30b11801be1eea71 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 12 Mar 2007 14:41:47 -0600 Subject: [PATCH] [POWERPC] bootwrapper: Preserve the pp pointer in ft_make_space() when calling ft_reorder(). The ft_reorder() function may change the start of the region of interest, so the pointer provided by the caller into that region must be fixed up to still point to the same datum.
