    Subject[PATCH v2 0/4] iommu/amd: Enable page-selective flushes
    Date
    From: Nadav Amit <namit@vmware.com>

    The previous patch, commit 268aa4548277 ("iommu/amd: Page-specific
    invalidations for more than one page") was supposed to enable
    page-selective IOTLB flushes on AMD.

    The patch had an embaressing bug, and I apologize for it.

    Analysis as for why this bug did not result in failures raised
    additional issues that caused at least most of the IOTLB flushes not to
    be page-selective ones.

    The first patch corrects the bug from the previous patch. The next
    patches enable page-selective invalidations, which were not enabled
    despite the previous patch.
