commit f08f7e88c99e8f17781945ddfbb0859f64c3a414
Author: Hauke Mehrtens <hauke at hauke-m.de>
AuthorDate: Sat Sep 24 13:33:37 2022 +0200

    kernel: Move some IOMMU options to generic
    
    This adds some missing IOMMU related options for x86/64 and moves some
    of them to generic for all targets.
    
    On x86 IOMMU_DEFAULT_DMA_LAZY is used by default, on all other platforms
    IOMMU_DEFAULT_DMA_STRICT is the default. we just follow the default
    kernel configuration here.
    
    Fixes: 8fea4a102ccd ("x86/64: enable IOMMU support")
