From e6b6e3ffb9ee8926f9f2f7dc9147df73e27d5828 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Mon, 27 Aug 2007 23:29:53 +0200 Subject: [POWERPC] Remove APUS support from arch/ppc Current status of APUS: - arch/powerpc/: removed in 2.6.23 - arch/ppc/: marked BROKEN since 2 years This therefore removes the remaining parts of APUS support from arch/ppc, include/asm-ppc, arch/powerpc and include/asm-powerpc.
