      "title": "drm/amdgpu: fix aperture mapping leak",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix aperture mapping leak\n\namdgpu_pci_remove() calls drm_dev_unplug() before invoking the driver\nfini routines. This causes drm_dev_enter() in amdgpu_ttm_fini() to\nalways return false, so iounmap(aper_base_kaddr) never runs on normal\ndriver unload, leaving an orphaned entry in the x86 PAT interval tree.\n\nOn connected_to_cpu hardware, the aperture is mapped write-back (WB) via\nioremap_cache(). On reload, IP discovery calls memremap(..., MEMREMAP_WC)\nover the same range. The WC vs WB conflict causes:\n\n  ioremap error for 0x..., requested 0x1, got 0x0\n  amdgpu: discovery failed: -2\n\nFix by switching to devres-managed mappings so cleanup is guaranteed\nregardless of drm_dev_enter() state:\n\n- connected_to_cpu path: devm_memremap(MEMREMAP_WB). For\n  IORESOURCE_SYSTEM_RAM ranges this takes the try_ram_remap() shortcut,\n  returning __va(offset) from the existing kernel direct map. No new\n  ioremap VA or PAT entry is created, so there is nothing to orphan.\n\n- dGPU path: devm_ioremap_wc() registers iounmap() as a devres action,\n  guaranteeing cleanup at device_del() time.\n\nAlso remove iounmap(aper_base_kaddr) from amdgpu_device_unmap_mmio()\nsince the mapping is now devres-owned.\n\nv2: Remove redundant x86_64 guard (Lijo)\n\n(cherry picked from commit d871e99879cb5fd1fa798b006b4888887e63a17a)",
