Security update for Linux kernel

The SUSE Linux Enterprise 11 Service Pack 2 kernel was updated to fix a regression introduced by the previous update:

* scsi_dh_alua: Incorrect reference counting in the SCSI ALUA
  initialization code lead to system crashes on boot (bnc#858831).

As the update introducing the regression was marked security, this is also marked security even though this bug is not security relevant.
