Yes, indeed. However, this is a bit tricky, because it can be associated
with different issues, and this particular fix is a follow up to an
another change [1] that I posted previously that defines arch-specific
structs target_ipc_perm and target_shmid_ds. The layout of the structs
is important.
This particular change will for instance, when joined with the
preceding change, make the code correctly return values in the buf
struct after:
shmctl(shm_id, IPC_STAT, &buf)
Different architectures benefit from these two patches.

Petar
