-Update the features after calling register_netdev() otherwise the
-device features are not set up correctly and it not possible to change
-the MTU of the device. After this change, the features reported by
-ethtool match the device's features before the commit which introduced
-the issue and it is possible to change the device's MTU.

+Subject: ext4: fix false negatives *and* false positives in
+ ext4_check_descriptors()
+
+Ext4_check_descriptors() was getting called before s_gdb_count was
+initialized.  So for file systems w/o the meta_bg feature, allocation
+bitmaps could overlap the block group descriptors and ext4 wouldn't
+notice.
+
+For file systems with the meta_bg feature enabled, there was a
+fencepost error which would cause the ext4_check_descriptors() to
+incorrectly believe that the block allocation bitmap overlaps with the
+block group descriptor blocks, and it would reject the mount.
+
+Fix both of these problems.

-Subject: mm: don't do zero_resv_unavail if memmap is not allocated
-
-From: Pavel Tatashin <pasha.tatashin@oracle.com>
-
-commit d1b47a7c9efcf3c3384b70f6e3c8f1423b44d8c7 upstream.
-
-Moving zero_resv_unavail before memmap_init_zone(), caused a regression on
-x86-32.
-
-The cause is that we access struct pages before they are allocated when
-CONFIG_FLAT_NODE_MEM_MAP is used.
-
-free_area_init_nodes()
-  zero_resv_unavail()
-    mm_zero_struct_page(pfn_to_page(pfn)); <- struct page is not alloced
-  free_area_init_node()
-    if CONFIG_FLAT_NODE_MEM_MAP
-      alloc_node_mem_map()
-        memblock_virt_alloc_node_nopanic() <- struct page alloced here
-
-On the other hand memblock_virt_alloc_node_nopanic() zeroes all the memory
-that it returns, so we do not need to do zero_resv_unavail() here.
-
