There are three head files(kallsyms.h, kernel.h and sections.h) which include the kernel sections range check, let's make some cleanup and unify them. 1. cleanup arch specific text/data check and fix address boundary check in kallsyms.h 2. make all the basic kernel range check function into sections.h 3. update all the callers, and use the helper in sections.h to simplify the code 4. use memory_intersects() in sections.h instead of private overlap for dma-debug Cc: linuxppc-dev@xxxxxxxxxxxxxxxx Cc: linux-s390@xxxxxxxxxxxxxxx Cc: linux-arch@xxxxxxxxxxxxxxx Cc: iommu@xxxxxxxxxxxxxxxxxxxxxxxxxx Cc: bpf@xxxxxxxxxxxxxxx Kefeng Wang (9): kallsyms: Remove arch specific text and data check kallsyms: Fix address-checks for kernel related range sections: Move and rename core_kernel_data() to is_kernel_data() sections: Move is_kernel_inittext() into sections.h kallsyms: Rename is_kernel() and is_kernel_text() sections: Add new is_kernel() and is_kernel_text() s390: kprobes: Use is_kernel() helper powerpc/mm: Use is_kernel_text() and is_kernel_inittext() helper dma-debug: Use memory_intersects() directly arch/powerpc/mm/pgtable_32.c | 7 +--- arch/s390/kernel/kprobes.c | 9 +---- arch/x86/kernel/unwind_orc.c | 2 +- arch/x86/net/bpf_jit_comp.c | 2 +- include/asm-generic/sections.h | 71 ++++++++++++++++++++++++++-------- include/linux/kallsyms.h | 21 +++------- include/linux/kernel.h | 2 - kernel/cfi.c | 2 +- kernel/dma/debug.c | 14 +------ kernel/extable.c | 33 ++-------------- kernel/locking/lockdep.c | 3 -- kernel/trace/ftrace.c | 2 +- mm/kasan/report.c | 2 +- net/sysctl_net.c | 2 +- 14 files changed, 76 insertions(+), 96 deletions(-) -- 2.26.2
