[ Upstream commit c23734487fb44ee16c1b007ba72d793c085e4ec4 ]
I have observed failures to boot on Orange Pi 3, because this driver
determined that my SoC is from the normal bin, but my SoC only works
reliably with the OPP values for the slowest bin.
By querying H6 owners, it was found that e-fuse values found in the wild
are in the range of 1-3, value of 7 was not reported, yet. From this and
from unused defines in BSP code, it can be assumed that meaning of efuse
values on H6 actually is:
- 1 = slowest bin
- 2 = normal bin
- 3 = fastest bin
Vendor code actually treats 0 and 2 as invalid efuse values, but later
treats all invalid values as a normal bin. This looks like a mistake in
bin detection code, that was plastered over by a hack in cpufreq code,
so let's not repeat it here. It probably only works because there are no
SoCs in the wild with efuse value of 0, and fast bin SoCs are made to
use normal bin OPP tables, which is also safe.
Let's play it safe and interpret 0 as the slowest bin, but fix detection
of other bins to match this research. More research will be done before
actual OPP tables are merged.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the ixgbe
driver still allowed TX packets to request HW timestamping. In this
situation, we see 'clearing Tx Timestamp hang' noise in the log.
Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

The check for the mmap support via hw_support_mmap() function misses
the case where the device is with SNDRV_DMA_TYPE_DEV_UC, which should
have been treated equally as SNDRV_DMA_TYPE_DEV. Let's fix it.
Note that this bug doesn't hit any practical problem, because
SNDRV_DMA_TYPE_DEV_UC is used only for x86-specific drivers
(snd-hda-intel and snd-intel8x0) for the specific platforms that need
the non-cached buffers. And, on such platforms, hw_support_mmap()
already returns true in anyway. That's the reason I didn't put
Cc-to-stable mark here. This is only for any theoretical future
extension.

As long as I investigated, some devices with BeBoB protocol version 1
can be freezed during several hundreds milliseconds after breaking
connections. When accessing during the freezed time, any transaction
is corrupted. In the worst case, the device is going to reboot.
I can see this issue in:
* Roland FA-66
* M-Audio FireWire Solo
This commit expands sleep just after breaking connections to avoid
the freezed time as much as possible. I note that the freeze/reboot
behaviour is similar to below models:
* Focusrite Saffire Pro 10 I/O
* Focusrite Saffire Pro 26 I/O
The above models certainly reboot after breaking connections.

Currently, if the loop device receives a WRITE_ZEROES request, it asks
the underlying filesystem to punch out the range. This behavior is
correct if unmapping is allowed. However, a NOUNMAP request means that
the caller doesn't want us to free the storage backing the range, so
punching out the range is incorrect behavior.
To satisfy a NOUNMAP | WRITE_ZEROES request, loop should ask the
underlying filesystem to FALLOC_FL_ZERO_RANGE, which is (according to
the fallocate documentation) required to ensure that the entire range is
backed by real storage, which suffices for our purposes.

With KASAN also enabled, we may also get many use-after-free reports.
The issue is that when CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, we may
attempt to detach the ata_port before it has been probed.
This is because the ata_ports are async probed, meaning that there is no
guarantee that the ata_port has probed prior to detach. When the ata_port
does probe in this scenario, we get all sorts of issues as the detach may
have already happened.
Fix by ensuring synchronisation with async_synchronize_full(). We could
alternatively use the cookie returned from the ata_port probe
async_schedule() call, but that means managing the cookie, so more
complicated.

This is problematic in this case, because the extcon notifier

Currently, the error return path when the call to function
dev->dfx->query_cqc_info fails will leak object 'context'. Fix this by
making the error return path via 'err' return return codes rather than
-EMSGSIZE, set ret appropriately for all error return paths and for the
memory leak now return via 'err' rather than just returning without
freeing context.

The Medion Akoya E2215T's ACPI _LID implementation is quite broken:
1. For notifications it uses an ActiveLow Edge GpioInt, rather then
an ActiveBoth one, meaning that the device is only notified when the
lid is closed, not when it is opened.
2. Matching with this its _LID method simply always returns 0 (closed)
In order for the Linux LID code to work properly with this implementation,
the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN.
This commit adds a DMI quirk for this.

The new check_zeroed_user() function uses variable shifts inside of a
user_access_begin()/user_access_end() section and that results in GCC
emitting __ubsan_handle_shift_out_of_bounds() calls, even though
through value range analysis it would be able to see that the UB in
question is impossible.
Annotate and whitelist this UBSAN function; continued use of
user_access_begin()/user_access_end() will undoubtedly result in
further uses of function.

The link detection timeouts can be observed (or link might not be detected
at all) when dp83867 PHY is configured in manual mode (speed/duplex).
CFG3[9] Robust Auto-MDIX option allows to significantly improve link detection
in case dp83867 is configured in manual mode and reduce link detection
time.
As per DM: "If link partners are configured to operational modes that are
not supported by normal Auto MDI/MDIX mode (like Auto-Neg versus Force
100Base-TX or Force 100Base-TX versus Force 100Base-TX), this Robust Auto
MDI/MDIX mode allows MDI/MDIX resolution and prevents deadlock."
Hence, enable this option by default as there are no known reasons
not to do so.

Since commit 92418fb147 ("i40e/i40evf: Use usec value instead of reg
value for ITR defines") the driver tracks the interrupt throttling
intervals in single usec units, although the actual ITRN/ITR0 registers are
programmed in 2 usec units. Most register programming flows in the driver
correctly handle the conversion, although it is currently not applied when
the registers are initialized to their default values. Most of the time
this doesn't present a problem since the default values are usually
immediately overwritten through the standard adaptive throttling mechanism,
or updated manually by the user, but if adaptive throttling is disabled and
the interval values are left alone then the incorrect value will persist.
Since the intended default interval of 50 usecs (vs. 100 usecs as
programmed) performs better for most traffic workloads, this can lead to
performance regressions.
This patch adds the correct conversion when writing the initial values to
the ITRN registers.

In cases like suspend-to-disk and suspend-to-ram, a large number of CPU
cores need to be shut down. At present, the CPU hotplug operation is
serialised, and the CPU cores can only be shut down one by one. In this
process, if PSCI affinity_info() does not return LEVEL_OFF quickly,
cpu_psci_cpu_kill() needs to wait for 10ms. If hundreds of CPU cores
need to be shut down, it will take a long time.
Normally, there is no need to wait 10ms in cpu_psci_cpu_kill(). So
change the wait interval from 10 ms to max 1 ms and use usleep_range()
instead of msleep() for more accurate timer.
In addition, reducing the time interval will increase the messages
output, so remove the "Retry ..." message, instead, track time and
output to the the sucessful message.

Instead let's rename drm_sched_cleanup_jobs() to
drm_sched_get_cleanup_job() and simply return a job for processing if
there is one. The caller can then call the free_job() callback outside
the wait_event_interruptible() where sleeping is possible before

We have a test case as follow:
mdadm -CR /dev/md1 -l 1 -n 4 /dev/sd[a-d] \
--assume-clean --bitmap=internal
mdadm -S /dev/md1
mdadm -A /dev/md1 /dev/sd[b-c] --run --force
mdadm --zero /dev/sda
mdadm /dev/md1 -a /dev/sda
echo offline > /sys/block/sdc/device/state
echo offline > /sys/block/sdb/device/state
sleep 5
mdadm -S /dev/md1
echo running > /sys/block/sdb/device/state
echo running > /sys/block/sdc/device/state
mdadm -A /dev/md1 /dev/sd[a-c] --run --force
When we readd /dev/sda to the array, it started to do recovery.
After offline the other two disks in md1, the recovery have
been interrupted and superblock update info cannot be written
to the offline disks. While the spare disk (/dev/sda) can continue
to update superblock info.
After stopping the array and assemble it, we found the array
run fail, with the follow kernel message:
[ 172.986064] md: kicking non-fresh sdb from array!
[ 173.004210] md: kicking non-fresh sdc from array!
[ 173.022383] md/raid1:md1: active with 0 out of 4 mirrors
[ 173.022406] md1: failed to create bitmap (-5)
[ 173.023466] md: md1 stopped.
Since both sdb and sdc have the value of 'sb->events' smaller than
that in sda, they have been kicked from the array. However, the only
remained disk sda is in 'spare' state before stop and it cannot be
added to conf->mirrors[] array. In the end, raid array assemble
and run fail.
In fact, we can use the older disk sdb or sdc to assemble the array.
That means we should not choose the 'spare' disk as the fresh disk in
analyze_sbs().
To fix the problem, we do not compare superblock events when it is
a spare disk, as same as validate_super.
