Merge series "use semicolons rather than commas to separate statements" from Julia Lawall <Julia.Lawall@inria.fr>:
These patches replace commas by semicolons. This was done using the
Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below.
This semantic patch ensures that commas inside for loop headers will not be
transformed. It also doesn't touch macro definitions.
Coccinelle ensures that braces are added as needed when a single-statement
branch turns into a multi-statement one.
This semantic patch has a few false positives, for variable delcarations
such as:
LIST_HEAD(x), *y;
The semantic patch could be improved to avoid these, but for the moment
they have been removed manually (2 occurrences).

Merge series "ASoC: sun8i-codec: support for AIF2 and AIF3" from Samuel Holland <samuel@sholland.org>:
This series adds support the other two AIFs present in the sun8i codec,
which can be used for codec2codec DAI links.
This series first fills out the DAI driver, removing assumptions that
were made for AIF1 (16 bits, 2 channels, certain clock inversions). Some
new logic is required to handle 3 DAIs and the ADC/DAC sharing the same
clock. Finally, it adds the new DAIs, and hooks them up with DAPM
widgets and routes per the hardware topology.
To minimize the number of patches in this series, related device tree
patches (increasing #sound-dai-cells, adding new DAI links) will be sent
separately.
Changes from v1:
- Patches 1-8 from v1 (DAPM changes) were merged
- Prefixed AIF constants with "SUN8I_CODEC_" [1, 7, 10, 16, 17]
- Renamed variables in sun8i_codec_set_fmt for clarity [3]
- Update sysclk->sysclk_rate if later calls to hw_params change the
sample rate (thanks Chen-Yu for reminding me of this) [11]
- Select COMMON_CLK for clk_set_rate_exclusive [12]
- Add comments and hopefully clarify the clock protection logic [12]
- Make the error message more concise and put it on one line [12]
- Drop the "reg" variable holding SUN8I_AIF_CLK_CTRL(dai->id) [15]
- Rename "div_reg" to "clk_reg" and adjust comments for clarity [17]
- Improve the AIF2/AIF3 rate mismatch error message [17]
- Minor grammar/wording fixes in commit messages [2, 4, 7, 8, 16, 17]
- Added Maxime's Acked-by: [1-2, 4-9, 11, 13-14, 16]

size to be 2 on i.MX8QM. And EDMA don't support to shift
the data from S24_LE to S16_LE, so the supported TX format
is also different on i.MX8QM.

The difference is
soc_pcm_hw_free() is for all dai/component/substream,

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_hw_free() and rollback.

This patch adds new soc_pcm_hw_clean() and call it from

This patch is for 3) snd_soc_dai_hw_params/free().
The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.
To avoid such case, this patch marks substream pointer when hw_params() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.
One note here is that it cares *previous* hw_params() only now,
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

ASoC: sun8i-codec: Add the AIF3 DAI, widgets, and routes
AIF3 has some differences from AIF1 and AIF2:
- It supports one channel only
- It supports master mode only
- It is not directly connected to any of the mixers; instead all audio
goes through a mux with AIF2.
- It does not have its own clock dividers; instead it reuses AIF2 BCLK
and LRCK. This means that when both AIF2 and AIF3 are active, they
must use the same sample rate and total frame width. Since AIF2 and
AIF3 are only used for codec2codec DAI links, constraints are not
applicable here; the only thing we can do when the rates don't match
is report an error.
Make the necessary adjustments to support this AIF.

ASoC: sun8i-codec: Automatically set the system sample rate
The sun8i codec has three clock/sample rate domains:
- The AIF1 domain, with a sample rate equal to AIF1 LRCK
- The AIF2 domain, with a sample rate equal to AIF2 LRCK
- The SYSCLK domain, containing the ADC, DAC, and effects (AGC/DRC),
with a sample rate given by a divisor from SYSCLK. The divisor is
controlled by the AIF1_FS or AIF2_FS field in SYS_SR_CTRL, depending
on if SYSCLK's source is AIF1CLK or AIF2CLK, respectively. The exact
sample rate depends on if SYSCLK is running at 22.6 MHz or 24.6 MHz.
When an AIF (currently only AIF1) is active, the ADC and DAC should run
at that sample rate to avoid artifacting. Sample rate conversion is only
available when multiple AIFs are active and are routed to each other;
this means the sample rate conversion hardware usually cannot be used.
Only attach the event hook to the channel 0 AIF widgets, since we only
need one event when a DAI stream starts or stops. Channel 0 is always
brought up with a DAI stream, regardless of the number of channels in
the stream.
The ADC and DAC (along with their effects blocks) can be used even if
no AIFs are in use. In that case, we should select an appropriate sample
rate divisor, instead of keeping the last-used AIF sample rate.
44.1/48 kHz was chosen to balance audio quality and power consumption.
Since the sample rate is tied to active AIF paths, disabling pmdown_time
allows switching to the optimal sample rate immediately, instead of
after a 5 second delay.

"Make prandom_u32() less predictable.
This is the cleanup of the latest series of prandom_u32
experimentations consisting in using SipHash instead of Tausworthe to
produce the randoms used by the network stack.
The changes to the files were kept minimal, and the controversial
commit that used to take noise from the fast_pool (
f227e3ec3b5c) was
reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
fed from various sources of activities (networking, scheduling) to
perturb the SipHash state using fast, non-trivially predictable data,
instead of keeping it fully deterministic. The goal is essentially to
make any occasional memory leakage or brute-force attempt useless.
The resulting code was verified to be very slightly faster on x86_64
than what is was with the controversial commit above, though this
remains barely above measurement noise. It was also tested on i386 and
arm, and build- tested only on arm64"

i2c: core: Restore acpi_walk_dep_device_list() getting called after registering the ACPI i2c devs
Commit
21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.

random32: add noise from network and scheduling activity
With the removal of the interrupt perturbations in previous random32
change (random32: make prandom_u32() output unpredictable), the PRNG
has become 100% deterministic again. While SipHash is expected to be
way more robust against brute force than the previous Tausworthe LFSR,
there's still the risk that whoever has even one temporary access to
the PRNG's internal state is able to predict all subsequent draws till
the next reseed (roughly every minute). This may happen through a side
channel attack or any data leak.
This patch restores the spirit of commit
f227e3ec3b5c ("random32: update
the net random state on interrupt and activity") in that it will perturb
the internal PRNG's statee using externally collected noise, except that
it will not pick that noise from the random pool's bits nor upon
interrupt, but will rather combine a few elements along the Tx path
that are collectively hard to predict, such as dev, skb and txq
pointers, packet length and jiffies values. These ones are combined
using a single round of SipHash into a single long variable that is
mixed with the net_rand_state upon each invocation.
The operation was inlined because it produces very small and efficient
code, typically 3 xor, 2 add and 2 rol. The performance was measured
to be the same (even very slightly better) than before the switch to
SipHash; on a 6-core 12-thread Core i7-8700k equipped with a 40G NIC
(i40e), the connection rate dropped from 556k/s to 555k/s while the
SYN cookie rate grew from 5.38 Mpps to 5.45 Mpps.

random32: make prandom_u32() output unpredictable
Non-cryptographic PRNGs may have great statistical properties, but
are usually trivially predictable to someone who knows the algorithm,
given a small sample of their output. An LFSR like prandom_u32() is
particularly simple, even if the sample is widely scattered bits.
It turns out the network stack uses prandom_u32() for some things like
random port numbers which it would prefer are *not* trivially predictable.
Predictability led to a practical DNS spoofing attack. Oops.
This patch replaces the LFSR with a homebrew cryptographic PRNG based
on the SipHash round function, which is in turn seeded with 128 bits
of strong random key. (The authors of SipHash have *not* been consulted
about this abuse of their algorithm.) Speed is prioritized over security;
attacks are rare, while performance is always wanted.
Replacing all callers of prandom_u32() is the quick fix.
Whether to reinstate a weaker PRNG for uses which can tolerate it
is an open question.
Commit
f227e3ec3b5c ("random32: update the net random state on interrupt
and activity") was an earlier attempt at a solution. This patch replaces
it.

Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"

KVM: ioapic: break infinite recursion on lazy EOI
During shutdown the IOAPIC trigger mode is reset to edge triggered
while the vfio-pci INTx is still registered with a resampler.
This allows us to get into an infinite loop:
ioapic_set_irq
-> ioapic_lazy_update_eoi
-> kvm_ioapic_update_eoi_one
-> kvm_notify_acked_irq
-> kvm_notify_acked_gsi
-> (via irq_acked fn ptr) irqfd_resampler_ack
-> kvm_set_irq
-> (via set fn ptr) kvm_set_ioapic_irq
-> kvm_ioapic_set_irq
-> ioapic_set_irq
Commit
8be8f932e3db ("kvm: ioapic: Restrict lazy EOI update to
edge-triggered interrupts", 2020-05-04) acknowledges that this recursion
loop exists and tries to avoid it at the call to ioapic_lazy_update_eoi,
but at this point the scenario is already set, we have an edge interrupt
with resampler on the same gsi.
Fortunately, the only user of irq ack notifiers (in addition to resamplefd)
is i8254 timer interrupt reinjection. These are edge-triggered, so in
principle they would need the call to kvm_ioapic_update_eoi_one from
ioapic_lazy_update_eoi, but they already disable AVIC(*), so they don't
need the lazy EOI behavior. Therefore, remove the call to
kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi.
This fixes CVE-2020-27152. Note that this issue cannot happen with
SR-IOV assigned devices because virtual functions do not have INTx,
only MSI.
