#       "IOMMU Fixes for Linux v4.19-rc5
#     
#        Three fixes queued up:
#     
#             - Warning fix for Rockchip IOMMU where there were IRQ handlers
#               for offlined hardware.
#     
#             - Fix for Intel VT-d because recent changes caused boot failures
#               on some machines because it tried to allocate to much
#               contiguous memory.
#     
#             - Fix for AMD IOMMU to handle eMMC devices correctly that appear
#               as ACPI HID devices."
