From dd56fdf23dfa0127d512b73d4238dbd2b5a7c1eb Mon Sep 17 00:00:00 2001 From: "jdl@freescale.com" Date: Wed, 7 Sep 2005 15:59:48 -0500 Subject: [PATCH] powerpc: Merge a few more include files Merge a few asm-ppc and asm-ppc64 header files. Note: the merge of setup.h intentionally does not carry forward the m68k cruft. That means this patch continues to break the already broken amiga on the ppc32.
