From 5669c3cf19fbadaa9120b59914beec8431277efe Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Tue, 2 Oct 2007 13:37:53 +1000 Subject: [POWERPC] Limit range of __init_ref_ok somewhat This patch introduces zalloc_maybe_bootmem and uses it so that we don't have to mark a whole (largish) routine as __init_ref_ok.
