* Windows memory descriptor list. In Windows, it's possible for
* buffers to be passed between user and kernel contexts without
* copying. Buffers may also be allocated in either paged or
* non-paged memory regions. An MDL describes the pages of memory
* used to contain a particular buffer. Note that a single MDL
* may describe a buffer that spans multiple pages. An array of
* page addresses appears immediately after the MDL structure itself.
* MDLs are therefore implicitly variably sized, even though they
* don't look it.
*
* Note that in FreeBSD, we can take many shortcuts in the way
* we handle MDLs because:
*
* - We are only concerned with pages in kernel context. This means
* we will only ever use the kernel's memory map, and remapping
* of buffers is never needed.
*
* - Kernel pages can never be paged out, so we don't have to worry
* about whether or not a page is actually mapped before going to
* touch it.

* The ndis_kspin_lock type is called KSPIN_LOCK in MS-Windows.
* 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.
