Provide generic versions in to make these helpers more easily usable. Changes since v2: - spelling fixes Changes since v1: - use slightly less nested macros - port a debug check from the old powerpc version to the generic code Diffstat: arch/alpha/include/asm/io.h | 1 - arch/arc/include/asm/io.h | 3 --- arch/arm/include/asm/memory.h | 6 ------ arch/arm64/include/asm/memory.h | 6 ------ arch/csky/include/asm/page.h | 3 --- arch/hexagon/include/asm/page.h | 6 ------ arch/loongarch/include/asm/page.h | 3 --- arch/m68k/include/asm/virtconvert.h | 3 --- arch/microblaze/include/asm/page.h | 1 - arch/mips/include/asm/io.h | 5 ----- arch/nios2/include/asm/io.h | 3 --- arch/openrisc/include/asm/page.h | 2 -- arch/parisc/include/asm/page.h | 1 - arch/powerpc/include/asm/io.h | 12 ------------ arch/riscv/include/asm/page.h | 3 --- arch/s390/include/asm/page.h | 2 -- arch/sh/include/asm/page.h | 1 - arch/sparc/include/asm/page.h | 2 -- arch/um/include/asm/pgtable.h | 2 -- arch/x86/include/asm/io.h | 5 ----- arch/xtensa/include/asm/page.h | 1 - include/asm-generic/memory_model.h | 13 +++++++++++++ 22 files changed, 13 insertions(+), 71 deletions(-) _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
