* Refreshed patches.
* Removed patches:
- target/linux/ar71xx/patches-4.9/103-MIPS-ath79-fix-register-address-in-ath79_ddr_wb_flus.patch superseded by upstream
- target/linux/ar71xx/patches-4.9/403-mtd_fix_cfi_cmdset_0002_status_check.patch superseded by upstream
- target/linux/brcm63xx/patches-4.9/001-4.11-01-mtd-m25p80-consider-max-message-size-in-m25p80_read.patch accepted upstream
- target/linux/brcm63xx/patches-4.9/001-4.15-08-bcm63xx_enet-correct-clock-usage.patch accepted upstream
- target/linux/brcm63xx/patches-4.9/001-4.15-09-bcm63xx_enet-do-not-write-to-random-DMA-channel-on-B.patch accepted upstream
- target/linux/generic/pending-4.9/900-gen_stats-fix-netlink-stats-padding.patch
* New backported patch to address ext4 breakage, introduced in 4.9.112:
- backport-4.9/500-ext4-fix-check-to-prevent-initializing-reserved-inod.patch
Also add ARM64_SSBD symbol to ARM64 targets still running kernel 4.9
Thanks to Koen Vandeputte for pointing out the need to add the ARM64_SSBD symbol, and the ext4 patch.
Compile-tested on: ar71xx

-Subject: [PATCH] MIPS: ath79: fix register address in ath79_ddr_wb_flush()
-
-ath79_ddr_wb_flush_base has the type void __iomem *, so register offsets
-need to be a multiple of 4.

-Subject: [PATCH 2/6] bcm63xx_enet: do not write to random DMA channel on
- BCM6345
-
-The DMA controller regs actually point to DMA channel 0, so the write to
-ENETDMA_CFG_REG will actually modify a random DMA channel.
-
-Since DMA controller registers do not exist on BCM6345, guard the write
-with the usual check for dma_has_sram.

+From: Theodore Ts'o <tytso at mit.edu>
+Date: Sat, 28 Jul 2018 08:12:04 -0400
+Subject: [PATCH] ext4: fix check to prevent initializing reserved inodes
+
+Commit 8844618d8aa7: "ext4: only look at the bg_flags field if it is
+valid" will complain if block group zero does not have the
+EXT4_BG_INODE_ZEROED flag set. Unfortunately, this is not correct,
+since a freshly created file system has this flag cleared. It gets
+almost immediately after the file system is mounted read-write --- but
+the following somewhat unlikely sequence will end up triggering a
+false positive report of a corrupted file system:
+
+ mkfs.ext4 /dev/vdc
+ mount -o ro /dev/vdc /vdc
+ mount -o remount,rw /dev/vdc
+
+Instead, when initializing the inode table for block group zero, test
+to make sure that itable_unused count is not too large, since that is
+the case that will result in some or all of the reserved inodes
+getting cleared.
+
+This fixes the failures reported by Eric Whiteney when running
+generic/230 and generic/231 in the the nojournal test case.
+
+Fixes: 8844618d8aa7 ("ext4: only look at the bg_flags field if it is valid")

-The gen_stats facility will add a header for the toplevel nlattr of type
-TCA_STATS2 that contains all stats added by qdisc callbacks. A reference
-to this header is stored in the gnet_dump struct, and when all the
-per-qdisc callbacks have finished adding their stats, the length of the
-containing header will be adjusted to the right value.
-
-However, on architectures that need padding (i.e., that don't set
-CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added
-before the stats, which means that the stored pointer will point to the
-padding, and so when the header is fixed up, the result is just a very
-big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS
-struct, this problem has been mostly invisible, but we exposed it with
-the netlink attribute-based statistics in CAKE.
-
-Fix the issue by fixing up the stored pointer if it points to a padding
-nlattr.
