[PATCH] powerpc/ppc64e: Fix link problem when building ppc64e_defconfig
From: Kumar Gala <hidden>
Date: 2010-10-08 16:00:16
Subsystem:
linux for powerpc (32-bit and 64-bit), linux for powerpc embedded ppc85xx, the rest · Maintainers:
Madhavan Srinivasan, Scott Wood, Linus Torvalds
arch/powerpc/platforms/built-in.o:(.toc1+0x18): undefined reference to `__early_start' This is due to the 85xx/smp.c not handling the 64-bit side properly. We need to set the entry point for secondary cores on ppc64e to generic_secondary_smp_init instead of __early_start that we due on ppc32.
