These are the messages I could find discussing the code that disables
PCI Master bit, before the code doing that was removed from ia64 tree:

<https://lists.linux-foundation.org/pipermail/fastboot/2006-June/010175.html>
<https://lists.linux-foundation.org/pipermail/fastboot/2006-June/010176.html>
<https://lists.linux-foundation.org/pipermail/fastboot/2006-June/010178.html>
<https://lists.linux-foundation.org/pipermail/fastboot/2006-June/010214.html>

May be it is time to revisit this, for more than just ia64.
