iommu: spapr_tce: Disable compile testing to fix build on book3s_32 config
Although SPAPR_TCE_IOMMU itself can be compile tested on certain PowerPC configurations, its presence makes arch/powerpc/kvm/Makefile to select modules which do not build in such configuration. The arch/powerpc/kvm/ modules use kvm_arch.spapr_tce_tables which exists only with CONFIG_PPC_BOOK3S_64. However these modules are selected when COMPILE_TEST and SPAPR_TCE_IOMMU are chosen leading to build failures: In file included from arch/powerpc/include/asm/book3s/64/mmu-hash.h:20:0, from arch/powerpc/kvm/book3s_64_vio_hv.c:22: arch/powerpc/include/asm/book3s/64/pgtable.h:17:0: error: "_PAGE_EXEC" redefined [-Werror] #define _PAGE_EXEC 0x00001 /* execute permission */ In file included from arch/powerpc/include/asm/book3s/32/pgtable.h:8:0, from arch/powerpc/include/asm/book3s/pgtable.h:8, from arch/powerpc/include/asm/pgtable.h:18, from include/linux/mm.h:95, from arch/powerpc/include/asm/io.h:29, from include/linux/io.h:13, from include/linux/irq.h:20, from arch/powerpc/include/asm/hardirq.h:6, from include/linux/hardirq.h:9, from include/linux/kvm_host.h:7, from arch/powerpc/kvm/book3s_64_vio_hv.c:12: arch/powerpc/include/asm/book3s/32/hash.h:29:0: note: this is the location of the previous definition #define _PAGE_EXEC 0x200 /* software: exec allowed */ Fixes: e93a1695d7fb ("iommu: Enable compile testing for some of drivers") Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200414142630.21153-1-krzk@kernel.org Signed-off-by: Joerg Roedel <jroedel@suse.de>
