ipc: Fix building compat mode without sysvipc (7e89a37c) · Commits · 戴 / test

As John Stultz noticed, my y2038 syscall series caused a link failure when CONFIG_SYSVIPC is disabled but CONFIG_COMPAT is enabled: arch/arm64/kernel/sys32.o:(.rodata+0x960): undefined reference to `__arm64_compat_sys_old_semctl' arch/arm64/kernel/sys32.o:(.rodata+0x980): undefined reference to `__arm64_compat_sys_old_msgctl' arch/arm64/kernel/sys32.o:(.rodata+0x9a0): undefined reference to `__arm64_compat_sys_old_shmctl' Add the missing entries in kernel/sys_ni.c for the new system calls.
