2021-08-16drm/amd/display: Ensure DCN save after VM setupJake Wang
[Why] DM initializes VM context after DMCUB initialization. This results in loss of DCN_VM_CONTEXT registers after z10. [How] Notify DMCUB when VM setup is complete, and have DMCUB save init registers. v2: squash in CONFIG_DRM_AMD_DC_DCN3_1 fix Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Acked-by: Wayne Lin <wayne.lin@amd.com> Signed-off-by: Jake Wang <haonan.wang2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Pin control needs to be activated by setting the enable bit, otherwise hardware rejects all pin changes. Previously this stayed unnoticed on Nexus 7 because pin control was enabled by default after rebooting from downstream kernel, which uses driver that enables the bit and charger registers are non-volatile until power supply (battery) is disconnected.

2021-08-16KVM: nSVM: always intercept VMLOAD/VMSAVE when nested (CVE-2021-3656)Maxim Levitsky
If L1 disables VMLOAD/VMSAVE intercepts, and doesn't enable Virtual VMLOAD/VMSAVE (currently not supported for the nested hypervisor), then VMLOAD/VMSAVE must operate on the L1 physical memory, which is only possible by making L0 intercept these instructions. Failure to do so allowed the nested guest to run VMLOAD/VMSAVE unintercepted, and thus read/write portions of the host physical memory.

2021-08-16spi: orion: Prevent incorrect chip select behaviourNathan Rossi
When clearing the chip-select mask, the controller will switch to chip selecting the native CS0 line. Because the control register chip-select mask is not updated in a single write this will cause undesirable chip-selection of CS0 even when requesting to select other native chip-select lines. This is additionally problematic as the chip-select may still be asserted. With the ARMADA 38x SoC the controller will assert both the desired native chip-select and CS0. To avoid any undesirable behaviour with the chip-select lines, update the control register with a single write. This avoids selecting CS0 and causes the (de-)assert to apply at the same time.

In 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()"), ttm_global_init was changed so that if creation of the debugfs global root directory fails, ttm_global_init will bail out early and return an error, leading to initialization failure of DRM drivers. However, not every system will be using debugfs. On such a system, debugfs directory creation can be expected to fail, but DRM drivers must still be usable. This changes it so that if creation of TTM's debugfs root directory fails, then no biggie: keep calm and carry on.

2021-08-16bnxt_en: Add missing DMA memory barriersMichael Chan
Each completion ring entry has a valid bit to indicate that the entry contains a valid completion event. The driver's main poll loop __bnxt_poll_work() has the proper dma_rmb() to make sure the valid bit of the next entry has been checked before proceeding further. But when we call bnxt_rx_pkt() to process the RX event, the RX completion event consists of two completion entries and only the first entry has been checked to be valid. We need the same barrier after checking the next completion entry. Add missing dma_rmb() barriers in bnxt_rx_pkt() and other similar locations.

2021-08-16tipc: call tipc_wait_for_connect only when dlen is not 0Xin Long
__tipc_sendmsg() is called to send SYN packet by either tipc_sendmsg() or tipc_connect(). The difference is in tipc_connect(), it will call tipc_wait_for_connect() after __tipc_sendmsg() to wait until connecting is done. So there's no need to wait in __tipc_sendmsg() for this case. This patch is to fix it by calling tipc_wait_for_connect() only when dlen is not 0 in __tipc_sendmsg(), which means it's called by tipc_connect().

2021-08-16mmc: sdhci-iproc: Cap min clock frequency on BCM2711Nicolas Saenz Julienne
There is a known bug on BCM2711's SDHCI core integration where the controller will hang when the difference between the core clock and the bus clock is too great. Specifically this can be reproduced under the following conditions: - No SD card plugged in, polling thread is running, probing cards at 100 kHz. - BCM2711's core clock configured at 500MHz or more. So set 200 kHz as the minimum clock frequency available for that board.

2021-08-15ALSA: hda/realtek: Enable 4-speaker output for Dell XPS 15 9510 laptopKristin Paget
The 2021-model XPS 15 appears to use the same 4-speakers-on-ALC289 audio setup as the Precision models, so requires the same quirk to enable woofer output. Tested on my own 9510.
