From cf0501328674849f8becf6de16620067a0c2f1b5 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 11 Jan 2006 22:46:27 +0100 Subject: [PATCH] x86_64: Move NUMA page_to_pfn/pfn_to_page functions out of line Saves about ~18K .text in defconfig There would be more optimization potential, but that's for later. Suggestion originally from Bill Irwin. Fix from Andy Whitcroft.
