Following fix handles the IQE so the kernel won't be trapped in an infinite loop. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> 
When hardware detects any error with a descriptor from the invalidation
queue, it stops fetching new descriptors from the queue until software
clears the Invalidation Queue Error bit in the Fault Status register.
Following fix handles the IQE so the kernel won't be trapped in an

The first patch supports variable page size. This provides support for IA64 which has multiple page sizes. This patch also adds some other code hooks for IA64 platform including DMAR_OPERATION_TIMEOUT definition.
