ARM: restart: remove poodle restart handler

The poodle restart handler was added in 74617fb6b8 (3593/1: Add reboot
and shutdown handlers for Zaurus handhelds), and at that time it was
necessary to deal with the RCSR register.  This commit also forced all
restarts to use the 'hard' restart method.

In dc38e2ad53 (pxa: Fix RCSR handling), the RCSR handling was removed,
leaving just the forcing to use a 'hard' restart.  As hard restarts are
the default (in the absense of a reboot= command line argument), this
seems pointless.  In any case, Richard Purdie says:

> From what I remember that hardware either always reboots or always
> halts. I think the option was therefore left hardcoded to make it clear

> Regardless, you can probably clean this up as you suggest now.

So, lets remove the unnecessary interception and rely on the default
restart mode.

VFS: we need to set LOOKUP_JUMPED on mountpoint crossing

Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.

Simple way to reproduce the problem in mainline:

    cat >/tmp/a.c <<'EOF'
    #include <unistd.h>
    #include <fcntl.h>
    #include <stdio.h>
    main()
    {
            struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
            if (fcntl(0, F_SETLK, &fl))
                    perror("setlk");
    }
    EOF
    cc /tmp/a.c -o /tmp/test

then on nfs4:

    mount --bind file1 file2
    /tmp/test < file1 # ok
    /tmp/test < file2 # spews "setlk: No locks available"...

What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.

The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks.  I.e.  set LOOKUP_JUMPED...
