commit abb280f799c47f76463b27d60f271208cbbf0c49
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Mon Oct 6 22:30:54 2014 +0000

    Move some chown / lchown / fchown definitions to syscalls.list (bug 14138).
    
    Continuing the move of syscall definitions to syscalls.list, where the
    removal of support for old kernel versions has made this possible,
    this patch moves various definitions of chown, lchown and fchown.
    
    In most cases the need for special syscalls.list entries (rather than
    existing generic ones) is because these architectures use chown32,
    lchown32 and fchown32 as syscall names.  Some architectures also have
    symbol versioning compatibility for older versions of chown having
    been equivalent to lchown.
    
    In the case of powerpc, chown.c (providing the chown@@GLIBC_2.1
    default version) is replaced by a syscalls.list entry (for powerpc32;
    powerpc64 has no need for this because of its more recent minimum
    symbol version, so can just use the entry in
    sysdeps/unix/syscalls.list), but lchown.S is left as-is because it
    provides the compat version of chown as an actual alias for __lchown,
    which is not yet supported by syscalls.list.  This file can be removed
    once such aliases are supported in syscalls.list.
