Subject: [PATCH] x86/mm: vmemmap and vmalloc base addressess are usngined
 longs

From: Jiri Kosina <jkosina@...e.cz>

Commits 9b46a051e4 ("x86/mm: Initialize vmemmap_base at boot-time") and 
a7412546d8 ("x86/mm: Adjust vmalloc base and size at boot-time") lost the 
type information for __VMALLOC_BASE_L4, __VMALLOC_BASE_L5, 
__VMEMMAP_BASE_L4 and __VMEMMAP_BASE_L5 constants.

Let's declare them explicitly unsigned long again.

Fixes: 9b46a051e4 ("x86/mm: Initialize vmemmap_base at boot-time")
Fixes: a7412546d8 ("x86/mm: Adjust vmalloc base and size at boot-time")
