(cherry picked from commit c2e92581da)
[Problem]
In some USB DACs, a terrible pop noise comes to be heard
at the start of DSD playback (in the following situations).
- play first DSD track
- change from PCM track to DSD track
- change from DSD64 track to DSD128 track (and etc...)
- seek DSD track
- Fast-Forward/Rewind DSD track
[Cause]
At the start of playback, there is a little silence.
The silence bit pattern "0x69" is required on DSD mode,
but it is not like that.
[Solution]
This patch adds DSD silence pattern to the endpoint settings.

commit 52f6490940 upstream
Skylake systems will receive a microcode update to address a TSX
errata. This microcode will (by default) clobber PMC3 when TSX
instructions are (speculatively or not) executed.
It also provides an MSR to cause all TSX transaction to abort and
preserve PMC3.
Add the CPUID enumeration and MSR definition.

commit 28928a3ce1 upstream.
In Odroid XU3 Lite board, the temperature levels reported for thermal
zone 0 were weird. In warm room:
/sys/class/thermal/thermal_zone0/temp:32000
/sys/class/thermal/thermal_zone1/temp:51000
/sys/class/thermal/thermal_zone2/temp:55000
/sys/class/thermal/thermal_zone3/temp:54000
/sys/class/thermal/thermal_zone4/temp:51000
Sometimes after booting the value was even equal to ambient temperature
which is highly unlikely to be a real temperature of sensor in SoC.
The thermal sensor's calibration (trimming) is based on fused values.
In case of the board above, the fused values are: 35, 52, 43, 58 and 43
(corresponding to each TMU device). However driver defined a minimum value
for fused data as 40 and for smaller values it was using a hard-coded 55
instead. This lead to mapping data from sensor to wrong temperatures
for thermal zone 0.
Various vendor 3.10 trees (Hardkernel's based on Samsung LSI, Artik 10)
do not impose any limits on fused values. Since we do not have any
knowledge about these limits, use 0 as a minimum accepted fused value.
This should essentially allow accepting any reasonable fused value thus
behaving like vendor driver.
The exynos5420-tmu-sensor-conf.dtsi is copied directly from existing
exynos4412 with one change - the samsung,tmu_min_efuse_value.

[ Upstream commit afc9f65e01 ]
When building the kernel as Thumb-2 with binutils 2.29 or newer, if the
assembler has seen the .type directive (via ENDPROC()) for a symbol, it
automatically handles the setting of the lowest bit when the symbol is
used with ADR. The badr macro on the other hand handles this lowest bit
manually. This leads to a jump to a wrong address in the wrong state
in the syscall return path:

To fix this, add a new symbol name which doesn't have ENDPROC used on it
and use that with badr. We can't remove the badr usage since that would

commit ec33745bcc upstream.
Commit 225da7e65a ("ARM: dts: add eMMC reset line for
exynos4412-odroid-common") added MMC power sequence for eMMC card of
Odroid X2/U3. It reused generic sd1_cd pin control configuration node
and only disabled pull-up. However that time the pinctrl configuration
was not applied during MMC power sequence driver initialization. This
has been changed later by commit d97a1e5d7c ("mmc: pwrseq: convert to
proper platform device").
It turned out then, that the provided pinctrl configuration is not
correct, because the eMMC_RTSN line is being re-configured as 'special
function/card detect function for mmc1 controller' not the simple
'output', thus the power sequence driver doesn't really set the pin
value. This in effect broke the reboot of Odroid X2/U3 boards. Fix this
by providing separate node with eMMC_RTSN pin configuration.

commit 38d589f2fd upstream.
With the ultimate goal of keeping rt_mutex wait_list and futex_q waiters
consistent it's necessary to split 'rt_mutex_futex_lock()' into finer
parts, such that only the actual blocking can be done without hb->lock
held.
Split split_mutex_finish_proxy_lock() into two parts, one that does the
blocking and one that does remove_waiter() when the lock acquire failed.
When the rtmutex was acquired successfully the waiter can be removed in the
acquisiton path safely, since there is no concurrency on the lock owner.
This means that, except for futex_lock_pi(), all wait_list modifications
are done with both hb->lock and wait_lock held.

[ Upstream commit 2b424cfc69 ]
Patch (b6c7a324df "MIPS: Fix get_frame_info() handling of
microMIPS function size.") introduces additional function size
check for microMIPS by only checking insn between ip and ip + func_size.
However, func_size in get_frame_info() is always 0 if KALLSYMS is not
enabled. This causes get_frame_info() to return immediately without
calculating correct frame_size, which in turn causes "Can't analyze
schedule() prologue" warning messages at boot time.
This patch removes func_size check, and let the frame_size check run
up to 128 insns for both MIPS and microMIPS.

When perf is built with the annobin plugin (RHEL8 build) extra symbols

...
Those symbols have no use for report or annotation and should be
skipped. Moreover they interfere with the DWARF unwind test on the PPC
arch, where they are mixed with checked symbols and then the test fails:
# perf test dwarf -v
59: Test dwarf unwind :
--- start ---
test child forked, pid 8515
unwind: .annobin_dwarf_unwind.c:ip = 0x10dba40dc (0x2740dc)
...
got: .annobin_dwarf_unwind.c 0x10dba40dc, expecting test__arch_unwind_sample
unwind: failed with 'no error'
The annobin symbols are defined as NOTYPE/LOCAL/HIDDEN:
# readelf -s ./perf | grep annobin | head -1
40: 00000000001bce4f 0 NOTYPE LOCAL HIDDEN 13 .annobin_init.c
They can still pass the check for the label symbol. Adding check for
HIDDEN and INTERNAL (as suggested by Nick below) visibility and filter
out such symbols.

[ Upstream commit 4e35c1cb94 ]
It is possible that two concurrent packets originating from the same
socket of a connection-less protocol (e.g. UDP) can end up having
different IP_CT_DIR_REPLY tuples which results in one of the packets
being dropped.
To illustrate this, consider the following simplified scenario:
1. Packet A and B are sent at the same time from two different threads
by same UDP socket. No matching conntrack entry exists yet.
Both packets cause allocation of a new conntrack entry.
2. get_unique_tuple gets called for A. No clashing entry found.
conntrack entry for A is added to main conntrack table.
3. get_unique_tuple is called for B and will find that the reply
tuple of B is already taken by A.
It will allocate a new UDP source port for B to resolve the clash.
4. conntrack entry for B cannot be added to main conntrack table
because its ORIGINAL direction is clashing with A and the REPLY
directions of A and B are not the same anymore due to UDP source
port reallocation done in step 3.
This patch modifies nf_conntrack_tuple_taken so it doesn't consider
colliding reply tuples if the IP_CT_DIR_ORIGINAL tuples are equal.
