2022-07-05drm/amdkfd: simplify vm_validate_pt_pd_bosLang Yu
We don't need to validate and map root PD specially here, it would be validated and mapped by amdgpu_vm_validate_pt_bos if it is evicted. The special case is when turning a GFX VM to a compute VM, if vm_update_mode changed, we should make sure root PD gets mapped. So just map root PD after updating vm->update_funcs in amdgpu_vm_make_compute whether the vm_update_mode changed or not. v3: - Add some comments suggested by Christian. v2: - Don't rename vm_validate_pt_pd_bos and make it public.

2022-07-05ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supportedMario Limonciello
commit 72f2ecb7ece7 ("ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported") added support for claiming to support CPPC in _OSC on non-Intel platforms. This unfortunately caused a regression on a vartiety of AMD platforms in the field because a number of AMD platforms don't set the `_OSC` bit 5 or 6 to indicate CPPC or CPPC v2 support. As these AMD platforms already claim CPPC support via a dedicated MSR from `X86_FEATURE_CPPC`, use this enable this feature rather than requiring the `_OSC` on platforms with a dedicated MSR. If there is additional breakage on the shared memory designs also missing this _OSC, additional follow up changes may be needed.

2022-07-05ACPI: CPPC: Only probe for _CPC if CPPC v2 is ackedMario Limonciello
Previously the kernel used to ignore whether the firmware masked CPPC or CPPCv2 and would just pretend that it worked. When support for the USB4 bit in _OSC was introduced from commit 9e1f561afb ("ACPI: Execute platform _OSC also with query bit clear") the kernel began to look at the return when the query bit was clear. This caused regressions that were misdiagnosed and attempted to be solved as part of commit 2ca8e6285250 ("Revert "ACPI: Pass the same capabilities to the _OSC regardless of the query flag""). This caused a different regression where non-Intel systems weren't able to negotiate _OSC properly. This was reverted in commit 2ca8e6285250 ("Revert "ACPI: Pass the same capabilities to the _OSC regardless of the query flag"") and attempted to be fixed by commit c42fa24b4475 ("ACPI: bus: Avoid using CPPC if not supported by firmware") but the regression still returned. These systems with the regression only load support for CPPC from an SSDT dynamically when _OSC reports CPPC v2. Avoid the problem by not letting CPPC satisfy the requirement in `acpi_cppc_processor_probe`.

Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages. * tag 'xsa-5.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/arm: Fix race in RB-tree based P2M accounting xen-netfront: restore __skb_queue_tail() positioning in xennet_get_responses() xen/blkfront: force data bouncing when backend is untrusted xen/netfront: force data bouncing when backend is untrusted xen/netfront: fix leaking data in shared pages xen/blkfront: fix leaking data in shared pages

The next patch is by Duy Nguyen and fixes the data transmission on R-Car V3U SoCs in the rcar_canfd driver. Rhett Aultman's patch fixes a DMA memory leak in the gs_usb driver. Liang He's patch removes an extra of_node_get() in the grcan driver. The next 2 patches are by me, target the m_can driver and fix the timestamp handling used for peripheral devices like the tcan4x5x. Jimmy Assarsson contributes 3 patches for the kvaser_usb driver and fixes CAN clock and bit timing related issues. The remaining 5 patches target the mcp251xfd driver.
