Modify all CPUID call sites which implicitly include any of the CPUID headers to explicitly include them instead. For KVM's reverse_cpuid.h, just include <asm/cpuid/types.h> since it references the CPUID_EAX..EDX symbols without using the CPUID APIs. Note, this allows removing the inclusion of <asm/cpuid/api.h> from within <asm/processor.h> next.

2026-05-06drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()Vitor Soares
The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep.

2026-05-06drm/bridge: ite-it6263: Move chip initialization code from probe to ↵Biju Das
atomic_enable On the RZ/G3L SMARC EVK, suspend to RAM powers down the ITE IT6263 chip. The display controller driver's system PM callbacks invoke drm_mode_config_helper_{suspend,resume}, which in turn call the bridge's atomic_{disable,enable} callbacks to handle suspend/resume for the bridge without dedicated PM ops. To support proper reinitialization after power loss, move reset_gpio into the it6263 struct so it is accessible beyond probe time. Relocate it6263_hw_reset(), it6263_lvds_set_i2c_addr(), it6263_lvds_config() and it6263_hdmi_config() from probe to atomic_enable, ensuring the chip is fully reset and reconfigured on every enable, including after a suspend/resume cycle.

This causes the PF own SW flag registers to be saved/restored rather than the target VF registers, silently corrupting migration state.

2026-05-05drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()Gustavo Sousa
When media GT is disabled via configfs, there is no allocation for media_gt, which is kept as NULL. In such scenario, intel_hdcp_gsc_check_status() results in a kernel pagefault error due to &gt->uc.gsc being evaluated as an invalid memory address. Fix that by introducing a NULL check on media_gt and bailing out early if so.

During gpu hot-unplug need check if there are kfd porcesses still using the being removed gpu before clean resources of the device. Current driver checks if kfd_processes_table is empty. kfd processes are not terminated after removed from kfd_processes_table immediately. They are still alive and may access the device until kfd_process_wq work queue got ran. Check kfd->kfd_processes_count value that is updated after kfd process got uninitialized when its ref becomes zero.

2026-05-05drm/amdgpu: zero-initialize GART table on allocationPhilip Yang
GART TLB is flushed after unmapping but not after mapping. Since amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a single PTE is written the TLB may speculatively load other uninitialized entries from the same cacheline. Those garbage entries can appear valid, and a subsequent write to another PTE in the same cacheline may cause the GPU to use a stale garbage PTE from the TLB. Fix this by calling memset_io() to zero-initialize the GART table with gart_pte_flags immediately after allocation. Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work since SDMA needs GART to be initialized to work.

2026-05-05drm/amdgpu/sdma4: replace BUG_ON with WARN_ON in fence emissionJohn B. Moore
sdma_v4_0_ring_emit_fence() contains two BUG_ON(addr & 0x3) assertions that verify fence writeback addresses are dword-aligned. These assertions can be reached from unprivileged userspace via crafted DRM_IOCTL_AMDGPU_CS submissions, causing a fatal kernel panic in a scheduler worker thread. Replace both BUG_ON() calls with WARN_ON() to log the condition without crashing the kernel. A misaligned fence address at this point indicates a driver bug, but crashing the kernel is never the correct response when the assertion is reachable from userspace. The CS IOCTL path is the correct place to filter invalid submissions; the ring emission callback is too late to do anything about it.

Used unsigned indices for loops bounded by unsigned counters and table sizes, while retaining signed types where values are semantically signed or participate in arithmetic that may legitimately go negative.
