See Documentation/Configure.help:

  You should mount the file system somewhere to be able to use
  POSIX shared memory. Adding the following line to /etc/fstab should
  take care of things:

  tmpfs         /dev/shm        tmpfs           defaults        0 0

  Remember to create the directory that you intend to mount tmpfs on
  if necessary (/dev/shm is automagically created if you use devfs).

It further directs you to Documentation/filesystems/tmpfs.txt

(All under linux source tree, probably a part of the kernel-docs rpm).
