PROBLEM:  (HPAQ41J00, QAR 64037)    (Patch ID: OSF440-044)
********
This patch fixes a problem where a system panic will occur when accessing an
ISO9660 format CDROM when the CDROM was mounted using the command:

        mount -r -t cdfs -o noversion /dev/rz4c /cdrom

The panic string is "Unaligned kernel space access from kernel mode".  A
typical stack trace of the crash is:

        6 panic(s = "Unaligned kernel space access from kernel mode")
        7 afault_trap
        8 _XentUna
        9 cdfs_isodir_to_idir
        10 cdfs_readisodir_int
        11 cdfs_readisodir
        12 cdnodeget
        13 cdfs_lookup
        14 namei
        15 stat1
        16 stat
        17 syscall
        18 _Xsyscall

This patch fixes a problem where the system can panic with the panic
string
"secsize_resid < d_reclen" when accessing a defective cdrom.  The stack
trace
of the panicing thread will be similar to:

   0 boot 
   1 panic
   2 cdfs_readdir
   3 getdirentries
   4 syscall
   5 _Xsyscall
