/*
 * alloc supplies three ingredients to the test framework that are all
 * related to the support of dynamic memory allocation.
 *
 * The first is a set of alloc function wrappers for malloc and its
 * friends. Using wrappers allows test code and common code to use the
 * same interface for memory allocation at all stages, even though the
 * implementations may change with the stage, e.g. pre/post paging.
 *
 * The second is a set of implementations for the alloc function
 * interfaces. These implementations are named early_*, as they can be
 * used almost immediately by the test framework.
 *
 * The third is a very simple physical memory allocator, which the
 * early_* alloc functions build on.
