ipc/shm.c: check for integer overflow during shmget.
SHMMAX is the upper limit for the size of a shared memory segment, counted in bytes. The actual allocation is that size, rounded up to the next full page. Add a check that prevents the creation of segments where the rounded up size causes an integer overflow.
