The ndis_kspin_lock type is called KSPIN_LOCK in MS-Windows.

Browse Source 
According to the Windows DDK header files, KSPIN_LOCK is defined like this:
	typedef ULONG_PTR KSPIN_LOCK;

From basetsd.h (SDK, Feb. 2003):
	typedef [public] unsigned __int3264 ULONG_PTR, *PULONG_PTR;
	typedef unsigned __int64 ULONG_PTR, *PULONG_PTR;
	typedef _W64 unsigned long ULONG_PTR, *PULONG_PTR;

The keyword __int3264 specifies an integral type that has the following
properties:
 + It is 32-bit on 32-bit platforms
 + It is 64-bit on 64-bit platforms
 + It is 32-bit on the wire for backward compatibility.
   It gets truncated on the sending side and extended appropriately
   (signed or unsigned) on the receiving side.

Thus register_t seems the proper mapping onto FreeBSD for spin locks.
