Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * GRU Chiplet:
- *   The GRU is a user addressible memory accelerator. It provides
- *   several forms of load, store, memset, bcopy instructions. In addition, it
- *   contains special instructions for AMOs, sending messages to message
- *   queues, etc.
- *
- *   The GRU is an integral part of the node controller. It connects
- *   directly to the cpu socket. In its current implementation, there are 2
- *   GRU chiplets in the node controller on each blade (~node).
- *
- *   The entire GRU memory space is fully coherent and cacheable by the cpus.
- *
- *   Each GRU chiplet has a physical memory map that looks like the following:
- *

- *
- *   Each of the "contexts" is a chunk of memory that can be mmaped into user
- *   space. The context consists of 2 parts:
- *
- *  	- an instruction space that can be directly accessed by the user
- *  	  to issue GRU instructions and to check instruction status.
- *
- *  	- a data area that acts as normal RAM.
- *
- *   User instructions contain virtual addresses of data to be accessed by the
- *   GRU. The GRU contains a TLB that is used to convert these user virtual
- *   addresses to physical addresses.
- *
- *   The "system control" area of the GRU chiplet is used by the kernel driver
- *   to manage user contexts and to perform functions such as TLB dropin and
- *   purging.
- *
- *   One context may be reserved for the kernel and used for cross-partition
- *   communication. The GRU will also be used to asynchronously zero out
- *   large blocks of memory (not currently implemented).
- *
- *
- * Tables:
- *
- * 	VDATA-VMA Data		- Holds a few parameters. Head of linked list of
- * 				  GTS tables for threads using the GSEG
- * 	GTS - Gru Thread State  - contains info for managing a GSEG context. A
- * 				  GTS is allocated for each thread accessing a
- * 				  GSEG.
- *     	GTD - GRU Thread Data   - contains shadow copy of GRU data when GSEG is
- *     				  not loaded into a GRU
- *	GMS - GRU Memory Struct - Used to manage TLB shootdowns. Tracks GRUs
- *				  where a GSEG has been loaded. Similar to
- *				  an mm_struct but for GRU.
- *
- *	GS  - GRU State 	- Used to manage the state of a GRU chiplet
- *	BS  - Blade State	- Used to manage state of all GRU chiplets
- *				  on a blade
- *
- *
- *  Normal task tables for task using GRU.
- *  		- 2 threads in process
- *  		- 2 GSEGs open in process
- *  		- GSEG1 is being used by both threads
- *  		- GSEG2 is used only by thread 2
- *

- *       task ---+---> mm ->------ (notifier) -------+-> gms
- *                     |                             |
