commit 2a4b25fad858ccae361afca6d4710e0e6b01b2b5
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Oct 10 00:56:17 2018 +0000

    Use common bits/shm.h for more architectures.
    
    sysdeps/unix/sysv/linux/bits/shm.h has padding after time fields in
    struct shmid_ds unconditionally, and thus is only suitable for 32-bit
    architectures (no 64-bit configurations use this file);
    sysdeps/unix/sysv/linux/generic/bits/shm.h is substantively the same,
    except that the padding is conditioned on __WORDSIZE == 32, and so it
    can be used for 64-bit architectures as well.
    
    This patch adds the conditionals to
    sysdeps/unix/sysv/linux/bits/shm.h.  The linux/generic/ version is
    then no longer needed and so is removed, as are the alpha and s390
    versions which are also no longer needed.  The other
    architecture-specific versions have different padding, layout, types
    or SHMLBA definitions and so are still needed after this change.
    
    This is essentially the same change for bits/shm.h as the bits/msq.h
    patch and the bits/sem.h patch.  However, the details of the padding
    variations for the architectures that aren't changed are not all the
    same between msqid_ds, shmid_ds and semid_ds.
    
    Tested with build-many-glibcs.py.
    
    	* sysdeps/unix/sysv/linux/bits/shm.h: Include <bits/wordsize.h>.
    	(struct shmid_ds): Condition padding after time fields on
    	[__WORDSIZE == 32].
    	* sysdeps/unix/sysv/linux/alpha/bits/shm.h: Remove file.
    	* sysdeps/unix/sysv/linux/generic/bits/shm.h: Likewise.
    	* sysdeps/unix/sysv/linux/s390/bits/shm.h: Likewise.
