Modify the initial trace output (which is based on flags in the binary
header) so that it is not done until after the magic number check.  This
may well not be a flat format binary, so the flags could be invalid.

If we have found aliased dentry that we return, inode reference is not
dropped and inode is not attached anywhere, so it seems the reference to
inode is leaked in that case.

Turn noatime and nodiratime into per-mount instead of per-sb flags.

After all the preparations this is a rather trivial patch.  The mount code
needs to treat the two options as per-mount instead of per-superblock, and
touch_atime needs to be changed to check the new MNT_ flags in addition to
the MS_ flags that are kept for filesystems that are always
noatime/nodiratime but not user settable anymore.  Besides that core code
only nfs needed an update because it's leaving atime updates to the server
and thus sets the S_NOATIME flag on every inode, but needs to know whether
it's a real noatime mount for an getattr optimization.

While we're at it I've killed the IS_NOATIME/IS_NODIRATIME macros that were
only used by touch_atime.

Now that all these entries in the arch ioctl32.c files are gone [1], we can
build fs/compat_ioctl.c as a normal object and kill tons of cruft.  We need a
special do_ioctl32_pointer handler for s390 so the compat_ptr call is done.
This is not needed but harmless on all other architectures.  Also remove some
superflous includes in fs/compat_ioctl.c

Tested on ppc64.

[1] parisc still had it's PPP handler left, which is not fully correct
    for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd
    kick in for all netdevice users.  We can introduce a proper handler
    in one of the next patch series by adding a compat_ioctl method to
    struct net_device but for now let's just kill it - parisc doesn't
    compile in mainline anyway and I don't want this to block this
    patchset.

This patch implements generic handling of RTC_IRQP_READ32, RTC_IRQP_SET32,
RTC_EPOCH_READ32 and RTC_EPOCH_SET32 in fs/compat_ioctl.c.  It's based on the
x86_64 code which needed a little massaging to be endian-clean.

parisc used COMPAT_IOCTL or generic w_long handlers for these whichce is wrong
and can't work because the ioctls encode sizeof(unsigned long) in their ioctl
number.  parisc also duplicated COMPAT_IOCTL entries for other rtc ioctls
which I remove in this patch, too.

After my lookup_hash patch ->d_revalidate always gets a valid struct nameidata
passed (unless you use lookup_one_len which autofs4 doesn't), so we can switch
it from update_atime to touch_atime.  This is a bit of an academic excercise
because autofs has a 1:1 vfsmount superblock relation, but I want to get rid
of update_atime so filesystems authors can't easily screw up per-mountpoint
noatime support.
