CVE-2026-93183

In the Linux kernel, the following vulnerability has been resolved:

drm/lima: call drm_mm_init() with a valid allocation range

lima_vm_create() is currently run before va_start and va_end are set up,
meaning they are both 0. lima_vm_create() runs drm_mm_init() with them
as arguments for the allocator, and if DRM_DEBUG_MM is enabled the
DRM_MM_BUG_ON check in drm_mm_init then fires, as seen here on
exynos4412-odroid-u2:

Fix the issue by moving the lima_vm_create() call after va_start and
va_end are set up.
