[PATCH] x86: Mark up large pm4/5 constants with UL

From: Chris Wilson
Date: Sun Apr 29 2018 - 07:50:26 EST


To silence sparse while maintaining compatibility with the assembly, use
_UL which conditionally only appends the UL suffix for C code.

Fixes: a7412546d8cb ("x86/mm: Adjust vmalloc base and size at boot-time")
