    iommu/omap: add logic to save/restore locked TLBs · c3b44a06
    Suman Anna authored
    The MMUs provide a mechanism to lock TLB entries to avoid
    eviction and fetching of frequently used page table entries.
    These TLBs lose context when the MMUs are turned OFF. Add the
    logic to save and restore these locked TLBS during suspend
    and resume respectively. There are no locked TLBs during
    initial power ON, and they need not be saved during final
    shutdown.
