IOMMU TLB flushing may be inadvertently suppressed

ISSUE DESCRIPTION An internal flag is used to temporarily suppress IOMMU TLB flushes, in order to consolidate multiple single page flushes into one wider flush. This flag is not cleared again, on certain error paths. This can result in TLB flushes not happening when they are needed. Retaining sta...
