Hi, This is v2 of my proposal to move set_memory_* function prototypes out of cacheflush.h and into their own header file. This came out of a comment Russell made while reviewing RODATA test cases http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/480855.html While the final result of that series was the rodata code was refactored into its own header file, the set_memory_* APIs are still out of place. This version refactored the common set_memory_* functions into an asm-generic header. s390x added some features so it can't just use the asm-generic header. I debated how much more to try and shove into the asm-generic version (e.g. stub prototypes for the ARM nommu case, set_kernel_text_*) but decided to stick with just the basics for this version. I split out the cacheflush.h -> set_memory.h conversions into separate patches to hopefully make merging easier. Worst case, the final patch to completely separate the two can be delayed if there are more problems found. I'd like for this to eventually go through the -mm tree so I'd like Acks where appropriate. As always, feedback appreciated. Thanks, Laura Laura Abbott (14): treewide: Move set_memory_* functions away from cacheflush.h arm: Use set_memory.h header arm64: Use set_memory.h header s390: Use set_memory.h header x86: Use set_memory.h header agp: Use set_memory.h header drm: Use set_memory.h header intel_th: Use set_memory.h header watchdog: hpwdt: Use set_memory.h header bpf: Use set_memory.h header module: Use set_memory.h header PM / hibernate: Use set_memory.h header ALSA: hda: Use set_memory.h header treewide: Decouple cacheflush.h and set_memory.h arch/arm/include/asm/cacheflush.h | 20 -------- arch/arm/include/asm/set_memory.h | 32 ++++++++++++ arch/arm/mm/pageattr.c | 1 + arch/arm/net/bpf_jit_32.c | 2 +- arch/arm64/include/asm/Kbuild | 1 + arch/arm64/include/asm/cacheflush.h | 5 -- arch/arm64/mm/pageattr.c | 1 + arch/arm64/net/bpf_jit_comp.c | 1 + arch/s390/include/asm/Kbuild | 1 + arch/s390/include/asm/cacheflush.h | 34 ------------- arch/s390/include/asm/set_memory.h | 31 ++++++++++++ arch/s390/kernel/ftrace.c | 1 + arch/s390/kernel/kprobes.c | 2 +- arch/s390/kernel/machine_kexec.c | 1 + arch/s390/mm/init.c | 1 + arch/s390/mm/pageattr.c | 1 + arch/s390/mm/vmem.c | 1 + arch/s390/net/bpf_jit_comp.c | 1 + arch/x86/include/asm/cacheflush.h | 85 ------------------------------- arch/x86/include/asm/set_memory.h | 87 ++++++++++++++++++++++++++++++++ arch/x86/kernel/amd_gart_64.c | 2 +- arch/x86/kernel/cpu/amd.c | 2 +- arch/x86/kernel/cpu/bugs.c | 2 +- arch/x86/kernel/ftrace.c | 2 +- arch/x86/kernel/machine_kexec_64.c | 1 + arch/x86/mm/init.c | 2 +- arch/x86/mm/init_64.c | 2 +- arch/x86/mm/ioremap.c | 2 +- arch/x86/mm/pageattr.c | 1 + arch/x86/net/bpf_jit_comp.c | 1 + arch/x86/pci/pcbios.c | 2 +- arch/x86/platform/efi/efi.c | 2 +- arch/x86/realmode/init.c | 2 +- drivers/char/agp/amd-k7-agp.c | 1 + drivers/char/agp/ati-agp.c | 1 + drivers/char/agp/generic.c | 2 +- drivers/char/agp/intel-gtt.c | 1 + drivers/char/agp/sworks-agp.c | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_gart.c | 1 + drivers/gpu/drm/gma500/gtt.c | 1 + drivers/gpu/drm/gma500/psb_drv.c | 1 + drivers/gpu/drm/radeon/radeon_gart.c | 1 + drivers/gpu/drm/ttm/ttm_page_alloc.c | 1 + drivers/gpu/drm/ttm/ttm_page_alloc_dma.c | 1 + drivers/gpu/drm/ttm/ttm_tt.c | 1 + drivers/hwtracing/intel_th/msu.c | 2 +- drivers/watchdog/hpwdt.c | 2 +- include/asm-generic/set_memory.h | 12 +++++ include/linux/filter.h | 2 +- kernel/module.c | 1 + kernel/power/snapshot.c | 1 + sound/pci/hda/hda_intel.c | 2 +- 52 files changed, 206 insertions(+), 161 deletions(-) create mode 100644 arch/arm/include/asm/set_memory.h delete mode 100644 arch/s390/include/asm/cacheflush.h create mode 100644 arch/s390/include/asm/set_memory.h create mode 100644 arch/x86/include/asm/set_memory.h create mode 100644 include/asm-generic/set_memory.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
