Subject: [PATCH] x86: Mark up large pm4/5 constants with UL
Date: Sun, 29 Apr 2018 12:48:32 +0100	[thread overview]
Message-ID: <20180429114832.14552-1-chris@chris-wilson.co.uk> (raw)

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")
