[PATCH] Shut up warnings in ipc/shm.c
Fix two warnings in ipc/shm.c
ipc/shm.c:122: warning: statement with no effect
ipc/shm.c:560: warning: statement with no effect
by converting the macros to empty inline functions. For safety, let's do
all three. This also has the advantage that typechecking gets performed
even without CONFIG_SHMEM enabled.
