On RISC-V, the build fails with:
In file included from mm/kfence/core.c:33: ./arch/riscv/include/asm/kfence.h: In function 'kfence_protect_page': ./arch/riscv/include/asm/kfence.h:59:9: error: implicit declaration of function 'local_flush_tlb_kernel_range'; did you mean 'flush_tlb_kernel_range'? [-Werror=implicit-function-declaration] 59 | local_flush_tlb_kernel_range(addr, addr + PAGE_SIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ | flush_tlb_kernel_range In file included from mm/kfence/report.c:20: ./arch/riscv/include/asm/kfence.h: In function 'kfence_protect_page': ./arch/riscv/include/asm/kfence.h:59:9: error: implicit declaration of function 'local_flush_tlb_kernel_range'; did you mean 'flush_tlb_kernel_range'? [-Werror=implicit-function-declaration] 59 | local_flush_tlb_kernel_range(addr, addr + PAGE_SIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ | flush_tlb_kernel_range
This is caused by commit d28e50e231ce20a9b9cad9edce139ac775421ce5 riscv: Fix IPIs usage in kfence_protect_page().
The function local_flush_tlb_kernel_range() doesn't exist for RISC-V in 5.15.x and doesn't appear until much later in 6.8-rc1. So probably best to drop this patch.
