Correct 8bc367384745. When iommu_domain_unload_entry() performs a
synchronous IOTLB invalidation, it must call dmar_domain_free_entry()
to remove the entry from the domain's RB_TREE.
Push down the acquisition and release of the DMAR lock into the
recently introduced function dmar_qi_invalidate_sync_locked() and
remove the _locked suffix.

iommu_gas: Eliminate a possible case of use-after-free
Eliminate a possible case of use-after-free in an error handling path
after a mapping failure. Specifically, eliminate IOMMU_MAP_ENTRY_QI_NF
and instead perform the IOTLB invalidation synchronously. Otherwise,
when iommu_domain_unload_entry() is called and told not to free the
IOMMU map entry, the caller could free the entry before dmar_qi_task()
is finished with it.

dmar: Disable protected memory regions after initialization
Some BIOSes protect memory region they reside in by using DMAR to
prevent devices from doing any DMA transactions to that part of RAM.
AMI refers to this as "DMA Control Guarantee".
Disable the protection when address translation is enabled.
I stumbled upon this while investigation a failing coredump on a device
which has this feature enabled.
