-/* This logic is all tentatively and, hopefully, will grow in usability.
- * For now, the kernel-mode build uses the memory manager that is
- * provided in the user-space build. That is awkward but reasonable for
- * the current level of support: At present, only memory protection is
- * provided. Kernel-mode code may call into user-mode code, but not
- * vice-versa. So hosting the memory manager in user-space allows the
- * memory manager to be shared in both kernel- and user-mode spaces.
- *
- * In the longer run, if an MMU is support that can provide virtualized
- * memory, then some SLAB memory manager will be required in kernel-space
- * with some kind of brk() system call to obtain mapped heap space.
- *
- * In the current build model, the user-space module is built first. The
- * file user_map.h is generated in the first pass and contains the
- * addresses of the memory manager needed in this file:

- * Name: kmalloc

- * Description:
- * This is a simple redirection to the user-space malloc() function.
- *
- * Parameters:
- * size - Size (in bytes) of the memory region to be allocated.
- *
- * Return Value:
- * The address of the allocated memory (NULL on failure to allocate)
- *
- * Assumptions:
- * 1. malloc() resides in user-space
- * 2. The address of the user space malloc() is provided in user_map.h
- * 3. The user-space malloc() is callable from kernel-space.
