[ Upstream commit 2e95f984aae4cf0608d0ba2189c756f2bd50b44a ]
When using the S/PDIF DAI, there is no requirement to call snd_soc_dai_set_fmt() as there is no DAI format definition that defines S/PDIF. In any case, S/PDIF does not have separate clocks, this is embedded into the data stream.
Consequently, when attempting to use TDA998x in S/PDIF mode, the attempt to configure TDA998x via the hw_params callback fails as the hdmi_codec_daifmt is left initialised to zero.
Since the S/PDIF DAI will only be used by S/PDIF, prepare the hdmi_codec_daifmt structure for this format.

[ Upstream commit 570f18b6a8d1f0e60e8caf30e66161b6438dcc91 ]
On HDaudio platforms, if playback is started when capture is working, there is no audible output.
This can be root-caused to the use of the rx|tx_mask to store an HDaudio stream tag.
If capture is stared before playback, rx_mask would be non-zero on HDaudio platform, then the channel number of playback, which is in the same codec dai with the capture, would be changed by soc_pcm_codec_params_fixup based on the tx_mask at first, then overwritten by this function based on rx_mask at last.
According to the author of tx|rx_mask, tx_mask is for playback and rx_mask is for capture. And stream direction is checked at all other references of tx|rx_mask in ASoC, so here should be an error. This patch checks stream direction for tx|rx_mask for fixup function.
This issue would affect not only HDaudio+ASoC, but also I2S codecs if the channel number based on rx_mask is not equal to the one for tx_mask. It could be rarely reproduecd because most drivers in kernel set the same channel number to tx|rx_mask or rx_mask is zero.
Tested on all platforms using stream_tag & HDaudio and intel I2S platforms.

After commit fbeec965b8d1c ("ASoC: samsung: odroid: Fix 32000 sample rate handling") the audio root clock frequency is configured improperly for 44100 sample rate. Due to clock rate rounding it's 20070401 Hz instead of 22579000 Hz. This results in a too low value of the PSR clock divider in the CPU DAI driver and too fast actual sample rate for fs=44100. E.g. 1 kHz tone has actual 1780 Hz frequency (1 kHz * 20070401/22579000 * 2).
Fix this by increasing the correction passed to clk_set_rate() to take into account inaccuracy of the EPLL frequency properly.

The CS4270 does not by default increment the register address on consecutive writes. During normal operation it doesn't matter as all register accesses are done individually. At resume time after suspend, however, the regcache code gathers the biggest possible block of registers to sync and sends them one on one go.
To fix this, set the INCR bit in all cases.

When an old ack_queue entry is used to store an incoming request, it may need to clean up the old entry if it is still referencing the MR. Originally only RDMA READ request needed to reference MR on the responder side and therefore the opcode was tested when cleaning up the old entry. The introduction of tid rdma specific operations in the ack_queue makes the specific opcode tests wrong. Multiple opcodes (RDMA READ, TID RDMA READ, and TID RDMA WRITE) may need MR ref cleanup.
Remove the opcode specific tests associated with the ack_queue.

[ Upstream commit 583feb08e7f7ac9d533b446882eb3a54737a6dbb ]
When an event is programmed with attr.wakeup_events=N (N>0), it means the caller is interested in getting a user level notification after N samples have been recorded in the kernel sampling buffer.
With precise events on Intel processors, the kernel uses PEBS. The kernel tries minimize sampling overhead by verifying if the event configuration is compatible with multi-entry PEBS mode. If so, the kernel is notified only when the buffer has reached its threshold. Other PEBS operates in single-entry mode, the kenrel is notified for each PEBS sample.
The problem is that the current implementation look at frequency mode and event sample_type but ignores the wakeup_events field. Thus, it may not be possible to receive a notification after each precise event.
This patch fixes this problem by disabling multi-entry PEBS if wakeup_events is non-zero.

Use parentheses around uses of the argument in u64_to_user_ptr() to ensure that the cast doesn't apply to part of the argument.
There are existing uses of the macro of the form
u64_to_user_ptr(A + B)
which expands to
(void __user *)(uintptr_t)A + B
(the cast applies to the first operand of the addition, the addition is a pointer addition). This happens to still work as intended, the semantic difference doesn't cause a difference in behavior.
But I want to use u64_to_user_ptr() with a ternary operator in the argument, like so:
u64_to_user_ptr(A ? B : C)
This currently doesn't work as intended.

You need to have CONFIG_SLAB=y and CONFIG_MEMCG=y to see the problem, because without MEMCG all slab caches are root caches, and the "list" node happens to be the right one.

Badly-designed systems might have (for example) active-high wake pins that default to high (e.g., because of external pull ups) until they have an active firmware which starts driving it low. This can cause an interrupt storm in the time between request_irq() and disable_irq().
We don't support shared interrupts here, so let's just pre-configure the interrupt to avoid auto-enabling it.

[ Upstream commit bf348f9b78d413e75bb079462751a1d86b6de36c ]
When tag_set->nr_maps is 1, the block layer limits the number of hw queues by nr_cpu_ids. No matter how many hw queues are used by virtio-blk, as it has (tag_set->nr_maps == 1), it can use at most nr_cpu_ids hw queues.
In addition, specifically for pci scenario, when the 'num-queues' specified by qemu is more than maxcpus, virtio-blk would not be able to allocate more than maxcpus vectors in order to have a vector for each queue. As a result, it falls back into MSI-X with one vector for config and one shared for queues.
Considering above reasons, this patch limits the number of hw queues used by virtio-blk by nr_cpu_ids.

Since commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are unconditionally gated off. Unfortunately this will break systems where these clocks are used for external purposes beyond the kernel's knowledge. Fix it by implementing a system specific quirk to mark the necessary pmc_plt_clks as critical.

syzbot is reporting uninitialized value at rpc_sockaddr2uaddr() [1]. This is because syzbot is setting AF_INET6 to "struct sockaddr_in"->sin_family (which is embedded into user-visible "struct nfs_mount_data" structure) despite nfs23_validate_mount_data() cannot pass sizeof(struct sockaddr_in6) bytes of AF_INET6 address to rpc_sockaddr2uaddr().
Since "struct nfs_mount_data" structure is user-visible, we can't change "struct nfs_mount_data" to use "struct sockaddr_storage". Therefore, assuming that everybody is using AF_INET family when passing address via "struct nfs_mount_data"->addr, reject if its sin_family is not AF_INET.

We have a VM_BUG_ON() to check that the page reference count doesn't underflow (or get close to overflow) by checking the sign of the count.
That's all fine, but we actually want to allow people to use a "get page ref unless it's already very high" helper function, and we want that one to use the sign of the page ref (without triggering this VM_BUG_ON).
Change the VM_BUG_ON to only check for small underflows (or _very_ close to overflowing), and ignore overflows which have strayed into negative territory.

This is the same as the traditional 'get_page()' function, but instead of unconditionally incrementing the reference count of the page, it only does so if the count was "safe". It returns whether the reference count was incremented (and is marked __must_check, since the caller obviously has to be aware of it).
Also like 'get_page()', you can't use this function unless you already had a reference to the page. The intent is that you can use this exactly like get_page(), but in situations where you want to limit the maximum reference count.
The code currently does an unconditional WARN_ON_ONCE() if we ever hit the reference count issues (either zero or negative), as a notification that the conditional non-increment actually happened.
NOTE! The count access for the "safety" check is inherently racy, but that doesn't matter since the buffer we use is basically half the range of the reference count (ie we look at the sign of the count).
