From: Gao Xiang <hsiangkao@redhat.com>
commit 0dcd3c94e02438f4a571690e26f4ee997524102a upstream.
Each ondisk inode should be aligned with inode slot boundary
(32-byte alignment) because of nid calculation formula, so all
compact inodes (32 byte) cannot across page boundary. However,
extended inode is now 64-byte form, which can across page boundary
in principle if the location is specified on purpose, although
it's hard to be generated by mkfs due to the allocation policy
and rarely used by Android use case now mainly for > 4GiB files.
For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't
be read from disk properly and cause out-of-bound memory read
with random value.
Let's fix now.

commit 1a1c130ab7575498eed5bcf7220037ae09cd1f8a upstream.
The following problem has been reported by George Kennedy:
Since commit 7fef431be9c9 ("mm/page_alloc: place pages to tail
in __free_pages_core()") the following use after free occurs
intermittently when ACPI tables are accessed.

ACPI tables mapped via kmap() do not have their mapped pages
reserved and the pages can be "stolen" by the buddy allocator.
Apparently, on the affected system, the ACPI table in question is
not located in "reserved" memory, like ACPI NVS or ACPI Data, that
will not be used by the buddy allocator, so the memory occupied by
that table has to be explicitly reserved to prevent the buddy
allocator from using it.
In order to address this problem, rearrange the initialization of the
ACPI tables on x86 to locate the initial tables earlier and reserve
the memory occupied by them.
The other architectures using ACPI should not be affected by this
change.

Commit 1a1c130ab757 ("ACPI: tables: x86: Reserve memory occupied by
ACPI tables") attempted to address an issue with reserving the memory
occupied by ACPI tables, but it broke the initrd-based table override
mechanism relied on by multiple users.
To restore the initrd-based ACPI table override functionality, move
the acpi_boot_table_init() invocation in setup_arch() on x86 after
the acpi_table_upgrade() one.

commit 2800aadc18a64c96b051bcb7da8a7df7d505db3f upstream.
It's possible for iwl_pcie_enqueue_hcmd() to be called with hard IRQs
disabled (e.g. from LED core). We can't enable BHs in such a situation.
Turn the unconditional BH-enable/BH-disable code into
hardirq-disable/conditional-enable.
This fixes the warning below.

commit 1d7ba0165d8206ac073f7ac3b14fc0836b66eae7 upstream
>From [1]
"GCC 10 (PR 91233) won't silently allow registers that are not
architecturally available to be present in the clobber list anymore,
resulting in build failure for mips*r6 targets in form of:
...
.../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target
146 | __asm__ volatile ( \
| ^~~~~~~
This is because base R6 ISA doesn't define hi and lo registers w/o DSP
extension. This patch provides the alternative clobber list for r6 targets
that won't include those registers."
Since kernel 5.4 and mips support for generic vDSO [2], the kernel fail to
build for mips r6 cpus with gcc 10 for the same reason as glibc.

commit b9b34ddbe2076ade359cd5ce7537d5ed019e9807 upstream.
The negation logic for the case where the off_reg is sitting in the
dst register is not correct given then we cannot just invert the add
to a sub or vice versa. As a fix, perform the final bitwise and-op
unconditionally into AX from the off_reg, then move the pointer from
the src to dst and finally use AX as the source for the original
pointer arithmetic operation such that the inversion yields a correct
result. The single non-AX mov in between is possible given constant
blinding is retaining it as it's not an immediate based operation.

Analogically to what we did in 2800aadc18a6 ("iwlwifi: Fix softirq/hardirq
disabling in iwl_pcie_enqueue_hcmd()"), we must apply the same fix to
iwl_pcie_gen2_enqueue_hcmd(), as it's being called from exactly the same
contexts.

This is another branded 8153 device that doesn't work well with LPM
enabled:
[ 400.597506] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71
So disable LPM to resolve the issue.

commit ca91fd8c7643d93bfc18a6fec1a0d3972a46a18a upstream.
Realtek Hub (0bda:5487) in Dell Dock WD19 sometimes fails to work
after the system resumes from suspend with remote wakeup enabled
device connected:
[ 1947.640907] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641208] usb 5-2.3-port5: cannot disable (err = -71)
[ 1947.641401] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641450] usb 5-2.3-port4: cannot reset (err = -71)
Information of this hub:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 10 Spd=480 MxCh= 5
D: Ver= 2.10 Cls=09(hub ) Sub=00 Prot=02 MxPS=64 #Cfgs= 1
P: Vendor=0bda ProdID=5487 Rev= 1.47
S: Manufacturer=Dell Inc.
S: Product=Dell dock
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=01 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=256ms

E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=256ms
The failure results from the ETIMEDOUT by chance when turning on
the suspend feature for the specified port of the hub. The port
seems to be in an unknown state so the hub_activate during resume
fails the hub_port_status, then the hub will fail to work.
The quirky hub needs the reset-resume quirk to function correctly.

From: Mark Pearson <markpearson@lenovo.com>
commit 6759e18e5cd8745a5dfc5726e4a3db5281ec1639 upstream.
On recent Thinkpad platforms it was reported that temp sensor 11 was
always incorrectly displaying 66C. It turns out the reason for this is
that this location in EC RAM is not a temperature sensor but is the
power supply ID (offset 0xC2).
Based on feedback from the Lenovo firmware team the EC RAM version can
be determined and for the current version (3) only the 0x78 to 0x7F
range is used for temp sensors. I don't have any details for earlier
versions so I have left the implementation unaltered there.
Note - in this block only 0x78 and 0x79 are officially designated (CPU &
GPU sensors). The use of the other locations in the block will vary from
platform to platform; but the existing logic to detect a sensor presence
holds.

commit 708fa01597fa002599756bf56a96d0de1677375c upstream.
Commit 146d62e5a586 ("ovl: detect overlapping layers") made sure we don't
have overlapping layers, but it also broke the arguably valid use case of
mount -olowerdir=/,upperdir=/subdir,..
where upperdir overlaps lowerdir on the same filesystem. This has been
causing regressions.
Revert the check, but only for the specific case where upperdir and/or
workdir are subdirectories of lowerdir. Any other overlap (e.g. lowerdir
is subdirectory of upperdir, etc) case is crazy, so leave the check in
place for those.
Overlaps are detected at lookup time too, so reverting the mount time check
should be safe.

Actually, both need to be removed because they are already in the tree:
$ git describe

$ git log --oneline v4.19.. sound/soc/codecs/ak4458.c sound/soc/codecs/ak5558.c

This applies to all branches.
