deadlock potential with VT-d and legacy PCI device pass-through

ISSUE DESCRIPTION When setting up interrupt remapping for legacy PCI-X devices, including PCI-X bridges, a lookup of the upstream bridge is required. This lookup, itself involving acquiring of a lock, is done in a context where acquiring that lock is unsafe. This can lead to a deadlock. IMPACT Th...
