* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_TMPFS_NAME.
	* sysdeps/unix/sysv/linux/shm_open.c [!__ASSUME_TMPFS_NAME]
	(where_is_shmfs): Don't test for obsolete shm filesystem name.

	* sysdeps/unix/sysv/linux/getsysstats.c: Don't search for proc
	mount point.  We assume procfs is mounted at /proc in many other
	places already.
