Module ptr 

Provides pointer wrappers for safely accessing userspace.

User pointers

TODO(doc).

Local pointers

TODO(doc).

All pointers provided from userspace should be accessed through a User to prevent kernelspace page faults from invalid or misaligned pointers.

SMAP

When SMAP is supported on the system, all memory access through a User will automatically set and clear the AC flag to prevent trapping.

Structs

PointerError

The error returned when a memory access to userspace failed.

TaggedNonNull

A [NonNull<T>] pointer with a numerical tag.
