+Subject: [PATCH 2/8] staging: r8188eu: Fix breakage introduced when 5G code
+ was removed
+
+In commit 221abd4d478a ("staging: r8188eu: Remove no more necessary definitions
+and code"), two entries were removed from RTW_ChannelPlanMap[], but not replaced
+with zeros. The position within this table is important, thus the patch broke
+systems operating in regulatory domains osted later than entry 0x13 in the table.
+Unfortunately, the FCC entry comes before that point and most testers did not see
+this problem.

+Subject: [PATCH 7/8] iommu: intel: do deep dma-unmapping, to avoid
+ kernel-flooding.
+
+Origins at :
+https://lists.linuxfoundation.org/pipermail/iommu/2021-October/thread.html
+
+=== Changes from v1 => v2 ===
+
+a)
+Improved patch-description.
+
+b)
+A more root-level fix, as suggested by
+
+	1.
+	Alex Williamson <alex.williamson@redhat.com>
+
+	2.
+	Lu Baolu <baolu.lu@linux.intel.com>
+
+=== Issue ===
+
+Kernel-flooding is seen, when an x86_64 L1 guest (Ubuntu-21) is booted in qemu/kvm
+on a x86_64 host (Ubuntu-21), with a host-pci-device attached.
+
+Following kind of logs, along with the stacktraces, cause the flood :
+
+......
+ DMAR: ERROR: DMA PTE for vPFN 0x428ec already set (to 3f6ec003 not 3f6ec003)
+ DMAR: ERROR: DMA PTE for vPFN 0x428ed already set (to 3f6ed003 not 3f6ed003)
+ DMAR: ERROR: DMA PTE for vPFN 0x428ee already set (to 3f6ee003 not 3f6ee003)
+ DMAR: ERROR: DMA PTE for vPFN 0x428ef already set (to 3f6ef003 not 3f6ef003)
+ DMAR: ERROR: DMA PTE for vPFN 0x428f0 already set (to 3f6f0003 not 3f6f0003)
+......
+
+=== Current Behaviour, leading to the issue ===
+
+Currently, when we do a dma-unmapping, we unmap/unlink the mappings, but
+the pte-entries are not cleared.
+
+Thus, following sequencing would flood the kernel-logs :
+
+i)
+A dma-unmapping makes the real/leaf-level pte-slot invalid, but the
+pte-content itself is not cleared.
+
+ii)
+Now, during some later dma-mapping procedure, as the pte-slot is about
+to hold a new pte-value, the intel-iommu checks if a prior
+pte-entry exists in the pte-slot. If it exists, it logs a kernel-error,
+along with a corresponding stacktrace.
+
+iii)
+Step ii) runs in abundance, and the kernel-logs run insane.
+
+=== Fix ===
+
+We ensure that as part of a dma-unmapping, each (unmapped) pte-slot
+is also cleared of its value/content (at the leaf-level, where the
+real mapping from a iova => pfn mapping is stored).
+
