    Subject[patch 27/45] tpm: interrupt clear fix
    -stable review patch.  If anyone has any objections, please let us know.

    ------------------
    From: Kylene Jo Hall <kjhall@us.ibm.com>

    Under stress testing I found that the interrupt is not always cleared.
    This is a bug and this patch should go into 2.6.18 and 2.6.17.x.
