| |
When I build kernel with ARCH=arm64, the building errors came out like this: CC mm/kfence/core.o In file included from ../mm/kfence/core.c:21: ../arch/arm64/include/asm/kfence.h: In function ‘kfence_protect_page’: ../arch/arm64/include/asm/kfence.h:12:2: error: implicit declaration of function ‘set_memory_valid’ [-Werror=implicit-function-declaration] 12 | set_memory_valid(addr, 1, !protect); | ^~~~~~~~~~~~~~~~ cc1: some warnings being treated as errors
which introduced by commit d54febeba2ff ("kfence: use pt_regs to generate stack trace on faults").
