  - target/linux/ar71xx/patches-4.9/403-mtd_fix_cfi_cmdset_0002_status_check.patch superseded by upstream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

* 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.

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 5012284700775a4e6e3fbe7eac4c543c4874b559 Mon Sep 17 00:00:00 2001
From: Theodore Ts'o <tytso@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")

target/linux/generic/pending-4.9/900-gen_stats-fix-netlink-stats-padding.patch
View File

@ -1,49 +0,0 @@
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.
