Thomas Hellstrom fd56746775 drm/vmwgfx: Protect from excessive execbuf kernel memory allocations v3 ... With the new validation code, a malicious user-space app could potentially submit command streams with enough buffer-object and resource references in them to have the resulting allocated validion nodes and relocations make the kernel run out of GFP_KERNEL memory. Protect from this by having the validation code reserve TTM graphics memory when allocating.
