jym 962a341df6 Change kvm_pa2off() and kvm_kvatop() prototypes (private to kvm(3)):
-int     _kvm_kvatop(kvm_t *, u_long, u_long *);
-off_t   _kvm_pa2off(kvm_t *, u_long);
+int     _kvm_kvatop(kvm_t *, vaddr_t, paddr_t *);
+off_t   _kvm_pa2off(kvm_t *, paddr_t);

Basically, use vaddr_t for VA and paddr_t for PA. In addition, for variables
representing addresses, use paddr_t or vaddr_t, depending on the context.

For most arches, vaddr_t and paddr_t are equivalent to unsigned long. However,
the change was needed for exotic situations, like i386 PAE, were unsigned long
is not suitable for PA which are 64 bits long. As this required a complete
change of the function prototypes, all arches had to be adapted accordingly.

Core files from before this commit should still work with the new code; I did
not see any direct dependency between core's structure and kvatop/pa2off.

The change was compile tested for all arches, as it impacts all of them.

Used as ground for u_long => vaddr_t/paddr_t replacements in kvm(3)
private functions.

bjh21 c4f68df178 Rename kvm_arm32.c to kvm_arm.c, since it's shared between arm32 and arm26.
The Makefile now finds the correct file without help.
