Copy *.dtbo files at arch/arm64/boot/dts/amlogic/overlays to boot
partition, e.g, /media/boot/overlays/. Then use "fdtoverlay" tool
to integrate DTB and DTBOs. Or, you also can use "fdt apply" u-boot
command to prepare device tree blob at booting time.

commit 435d1a4715 upstream.
In most cases, such as CONFIG_ACPI_CUSTOM_DSDT and
CONFIG_ACPI_TABLE_UPGRADE, boot-time modifications to firmware tables
are tied to specific Kconfig options. Currently this is not the case
for modifying the ACPI SSDT via the efivar_ssdt kernel command line
option and associated EFI variable.
This patch adds CONFIG_EFI_CUSTOM_SSDT_OVERLAYS, which defaults
disabled, in order to allow enabling or disabling that feature during
the build.

Could you please push this patch into stable@?
it fixes memory corruption in kernels v3.5 .. v4.10
Lost .data_len definition leads to write beyond end of
struct nf_ct_h323_master. Usually it corrupts following
struct nf_conn_nat, however if nat is not loaded it corrupts
following slab object.
In mainline this problem went away in v4.11,
after commit 9f0f3ebeda ("netfilter: helpers: remove data_len usage
for inkernel helpers") however many stable kernels are still affected.
Fixes: 1afc56794e ("netfilter: nf_ct_helper: implement variable length helper private data") # v3.5

commit fcec538ef8 upstream.
This resolves the hazard between the mtc0 in the change_c0_status() and
the mfc0 in configure_exception_vector(). Without resolving this hazard
configure_exception_vector() could read an old value and would restore
this old value again. This would revert the changes change_c0_status()
did. I checked this by printing out the read_c0_status() at the end of
per_cpu_trap_init() and the ST0_MX is not set without this patch.
The hazard is documented in the MIPS Architecture Reference Manual Vol.
III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev
6.03 table 8.1 which includes:
Producer | Consumer | Hazard
----------|----------|----------------------------
mtc0 | mfc0 | any coprocessor 0 register
I saw this hazard on an Atheros AR9344 rev 2 SoC with a MIPS 74Kc CPU.
There the change_c0_status() function would activate the DSPen by
setting ST0_MX in the c0_status register. This was reverted and then the
system got a DSP exception when the DSP registers were saved in
save_dsp() in the first process switch. The crash looks like this:
[ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear)
[ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear)
[ 0.107070] Kernel panic - not syncing: Unexpected DSP exception
[ 0.113470] Rebooting in 1 seconds..
We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs,
not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with
kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it
did not happen.
In the kernel I bisected this problem to commit 9012d01166 ("compiler:
allow all arches to enable CONFIG_OPTIMIZE_INLINING"), but when this was
reverted it also happened after commit 172dcd935c ("MIPS: Always
allocate exception vector for MIPSr2+").
Commit 0b24cae4d5 ("MIPS: Add missing EHB in mtc0 -> mfc0 sequence.")
does similar changes to a different file. I am not sure if there are
more places affected by this problem.

commit 9ffad9263b upstream.
When xfstest generic/035, we found the target file was deleted
if the rename return -EACESS.
In cifs_rename2, we unlink the positive target dentry if rename
failed with EACESS or EEXIST, even if the target dentry is positived
before rename. Then the existing file was deleted.
We should just delete the target file which created during the
rename.

commit cc15461c73 upstream.
Ensure multiuser SMB3 mounts use encryption for all users' tcons if the
mount options are configured to require encryption. Without this, only
the primary tcon and IPC tcons are guaranteed to be encrypted. Per-user
tcons would only be encrypted if the server was configured to require
encryption.

[ Upstream commit cd217f2300 ]
The PCA9665 datasheet says that I2CSTA = 78h indicates that SCL is stuck
low, this differs to the PCA9564 which uses 90h for this indication.
Treat either 0x78 or 0x90 as an indication that the SCL line is stuck.
Based on looking through the PCA9564 and PCA9665 datasheets this should
be safe for both chips. The PCA9564 should not return 0x78 for any valid
state and the PCA9665 should not return 0x90.
