From d0e15bed84db7a9b0ea85d2ad9707b5e6d2e38da Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Sun, 23 Apr 2006 10:42:04 +1000 Subject: [PATCH] powerpc: Fix define_machine so machine_is() works from modules machine_is() was always returning 0 when used in a module, because we weren't exporting the machine definitions. This was why sound wasn't working on powermacs when CONFIG_SND_POWERMAC=m. Original fix from Ben Herrenschmidt, further fixed by me.
