/usr/src/sys/vm/vm_contig.c:319:1: error: conflicting types for 
'kmem_alloc_contig'
kmem_alloc_contig(vm_map_t map, vm_size_t size, int flags, vm_paddr_t low,
^
/usr/src/sys/vm/vm_extern.h:46:13: note: previous declaration is here
vm_offset_t kmem_alloc_contig(vm_map_t map, vm_size_t size, int flags,
             ^
1 error generated.

vm_extern.h:
vm_offset_t kmem_alloc_contig(vm_map_t map, vm_size_t size, int flags,
     vm_paddr_t low, vm_paddr_t high, unsigned long alignment,
     unsigned long boundary, vm_memattr_t memattr);

Why boundary is unsigned long and not vm_paddr_t?

vm_contig.c:
vm_offset_t
kmem_alloc_contig(vm_map_t map, vm_size_t size, int flags, vm_paddr_t low,
      vm_paddr_t high, u_long alignment, vm_paddr_t boundary,
      vm_memattr_t memattr)

That was caused by radeon drm patches found at
