Fix failures in powerpc associated with the previously allowed implicit module.h presence that now lead to things like this: arch/powerpc/mm/mmu_context_hash32.c:76:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' arch/powerpc/mm/tlb_hash32.c:48:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/kernel/pci_32.c:51:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' arch/powerpc/kernel/iomap.c:36:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/platforms/44x/canyonlands.c:126:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/kvm/44x.c:168:59: error: 'THIS_MODULE' undeclared (first use in this function) [with several contibutions from Stephen Rothwell <sfr@canb.auug.org.au>] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
