Fedor Pchelkin 7ed2632ec7 drm/ttm: fix ttm pool initialization for no-dma-device drivers ... The QXL driver doesn't use any device for DMA mappings or allocations so dev_to_node() will panic inside ttm_device_init() on NUMA systems: general protection fault, probably for non-canonical address 0xdffffc000000007a: 0000 [#1] PREEMPT SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x00000000000003d0-0x00000000000003d7] CPU: 1 PID: 1 Comm: swapper/0 Not tainted 6.7.0+ #9 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-3-gd478f380-rebuilt.opensuse.org 04/01/2014 RIP: 0010:ttm_device_init+0x10e/0x340 Call Trace: qxl_ttm_init+0xaa/0x310 qxl_device_init+0x1071/0x2000 qxl_pci_probe+0x167/0x3f0 local_pci_probe+0xe1/0x1b0 pci_device_probe+0x29d/0x790 really_probe+0x251/0x910 __driver_probe_device+0x1ea/0x390 driver_probe_device+0x4e/0x2e0 __driver_attach+0x1e3/0x600 bus_for_each_dev+0x12d/0x1c0 bus_add_driver+0x25a/0x590 driver_register+0x15c/0x4b0 qxl_pci_driver_init+0x67/0x80 do_one_initcall+0xf5/0x5d0 kernel_init_freeable+0x637/0xb10 kernel_init+0x1c/0x2e0 ret_from_fork+0x48/0x80 ret_from_fork_asm+0x1b/0x30 RIP: 0010:ttm_device_init+0x10e/0x340 Fall back to NUMA_NO_NODE if there is no device for DMA.
