[ Upstream commit 83a196773b8bc6702f49df1eddc848180e350340 ]

Analogix_dp driver acquires all its resources in the ->bind() callback, what is a bit against the component driver based approach, where the driver initialization is split into a probe(), where all resources are gathered, and a bind(), where all objects are created and a compound driver is initialized.

Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function.

This fixes the multiple calls to the bind() of the DRM compound driver when the DP PHY driver is not yet loaded/probed:

[ Upstream commit b87080eab4c1377706c113fc9c0157f19ea8fed1 ]

After successfully running the IPC msgque test once, subsequent runs result in a test failure:

$ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1

The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test.

The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values.

Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

[ Upstream commit 15ce30609d1e88d42fb1cd948f453e6d5f188249 ]

There are 2 registers to write to enable a ptp ref clock coming from the fpga. One that enables the usage of the clock from the fpga for emac0 and emac1 as a ptp ref clock, and the other to allow signals from the fpga to reach emac0 and emac1. Currently, if the dwmac-socfpga has phymode set to PHY_INTERFACE_MODE_MII, PHY_INTERFACE_MODE_GMII, or PHY_INTERFACE_MODE_SGMII, both registers will be written and the ptp ref clock will be set as coming from the fpga. Separate the 2 register writes to only enable signals from the fpga to reach emac0 or emac1 when ptp ref clock is not coming from the fpga.

[ Upstream commit 0c258657ddfe81b4fc0183378d800c97ba0b7cdd ]

The master SSI of a multi-SSI setup was attached both to the RSND_MOD_SSI slot and the RSND_MOD_SSIP slot of the rsnd_dai_stream. This is not correct wrt. the meaning of being "parent" in the rest of the SSI code, where it seems to indicate an SSI that provides clock and word sync but is not transmitting/receiving audio data.

Not treating the multi-SSI master as parent allows removal of various special cases to the rsnd_ssi_is_parent conditions introduced in commit a09fb3f28a60 ("ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode"). It also fixes the issue that operations performed via rsnd_dai_call() were performed twice for the master SSI. This caused some "status check failed" spam when stopping a multi-SSI stream as the driver attempted to stop the master SSI twice.

[ Upstream commit 65303de829dd6d291a4947c1a31de31896f8a060 ]

This disables tcon re-use for DFS shares.

tcon->dfs_path stores the path that the tcon should connect to when doing failing over.

If that tcon is used multiple times e.g. 2 mounts using it with different prefixpath, each will need a different dfs_path but there is only one tcon. The other solution would be to split the tcon in 2 tcons during failover but that is much harder.

tcons could not be shared with DFS in cifs.ko because in a DFS namespace like:

//domain/dfsroot -> /serverA/dfsroot, /serverB/dfsroot

//serverA/dfsroot/link -> /serverA/target1/aa/bb

//serverA/dfsroot/link2 -> /serverA/target1/cc/dd

you can see that link and link2 are two DFS links that both resolve to the same target share (/serverA/target1), so cifs.ko will only contain a single tcon for both link and link2.

The problem with that is, if we (auto)mount "link" and "link2", cifs.ko will only contain a single tcon for both DFS links so we couldn't perform failover or refresh the DFS cache for both links because tcon->dfs_path was set to either "link" or "link2", but not both -- which is wrong.

[ Upstream commit ecaeceb8a8a145d93c7e136f170238229165348f ]

The driver is designed to drop Rx packets and reclaim the buffers when an allocation fails, and the network interface needs to safely handle this packet loss. Therefore, an allocation failure of Rx SKBs is relatively benign.

However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing.

This commit suppresses the warning messages to prevent scheduling problems while retaining the failure count in the statistics of the network interface.

commit 977dfef40c8996b69afe23a9094d184049efb7bb upstream.

The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a new blacklist for the devices that are known to have empty codecs, and one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f). However, it turned out that the very same PCI SSID is used for the previous model that does have the valid HD-audio codecs and the change broke the sound on it.

Since the empty codec problem appear on the certain AMD platform (PCI ID 1022:1487), this patch changes the blacklist matching to both PCI ID and SSID using pci_match_id(). Also, the entry that was removed by the previous fix for ASUS ROG Zenigh II is re-added.

commit 68a33b1794665ba8a1d1ef1d3bfcc7c587d380a6 upstream.

The valid memory address check in dma_capable only makes sense when mapping normal memory, not when using dma_map_resource to map a device resource. Add a new boolean argument to dma_capable to exclude that check for the dma_map_resource case.

commit b2a84de2a2deb76a6a51609845341f508c518c03 upstream.

Commit dcde237319e6 ("mm: Avoid creating virtual address aliases in brk()/mmap()/mremap()") changed mremap() so that only the 'old' address is untagged, leaving the 'new' address in the form it was passed from userspace. This prevents the unexpected creation of aliasing virtual mappings in userspace, but looks a bit odd when you read the code.

Add a comment justifying the untagging behaviour in mremap().

To get the changes in:

Silencing this tools/perf/ build warning:

Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/unistd.h' differs from latest version at 'arch/arm64/include/uapi/asm/unistd.h' diff -u tools/arch/arm64/include/uapi/asm/unistd.h arch/arm64/include/uapi/asm/unistd.h

Which will probably end up enabling the use of "clone3" in 'perf trace -e', haven't checked the build with this change on an arm64 system.

commit e1e047ace8cef6d143f38c7d769753f133becbe6 upstream.

Commit 2abb0d5268ae ("PM / devfreq: Lock devfreq in trans_stat_show") revealed a missing locking while calling devfreq_update_status() function during suspend/resume cycle.

Code analysis revealed that devfreq_set_target() function was called without needed locks held for setting device specific suspend_freq if such has been defined. This patch fixes that by adding the needed locking, what fixes following kernel warning on Exynos4412-based OdroidU3 board during system suspend:
