When building with: CONFIG_64BIT=y CONFIG_MIPS32_COMPAT=y CONFIG_COMPAT=y CONFIG_MIPS32_O32=y CONFIG_MIPS32_N32=y CONFIG_SYSVIPC is not set (and implicitly: CONFIG_SYSVIPC_COMPAT is not set) the final link fails with unresolved symbols for: compat_sys_semctl, compat_sys_msgsnd, compat_sys_msgrcv, compat_sys_shmctl, compat_sys_msgctl, compat_sys_semtimedop The fix is to add cond_syscall declarations for all syscalls in ipc/compat.c Signed-off-by: Kevin Cernekee <cernekee@xxxxxxxxx> Acked-by: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Cc: Al Viro <viro@xxxxxxxxxxxxxxxxxx> Cc: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> --- kernel/sys_ni.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-) diff --git a/kernel/sys_ni.c b/kernel/sys_ni.c index 25cc41c..1140c12 100644 --- a/kernel/sys_ni.c +++ b/kernel/sys_ni.c @@ -69,15 +69,22 @@ cond_syscall(compat_sys_epoll_pwait); cond_syscall(sys_semget); cond_syscall(sys_semop); cond_syscall(sys_semtimedop); +cond_syscall(compat_sys_semtimedop); cond_syscall(sys_semctl); +cond_syscall(compat_sys_semctl); cond_syscall(sys_msgget); cond_syscall(sys_msgsnd); +cond_syscall(compat_sys_msgsnd); cond_syscall(sys_msgrcv); +cond_syscall(compat_sys_msgrcv); cond_syscall(sys_msgctl); +cond_syscall(compat_sys_msgctl); cond_syscall(sys_shmget); cond_syscall(sys_shmat); +cond_syscall(compat_sys_shmat); cond_syscall(sys_shmdt); cond_syscall(sys_shmctl); +cond_syscall(compat_sys_shmctl); cond_syscall(sys_mq_open); cond_syscall(sys_mq_unlink); cond_syscall(sys_mq_timedsend); -- 1.7.5
