When a heapbuf object is created, there are two memory buffers allocated -- one
for the handle and one for the object itself.  That is in _heapbuf_create.  In
heapbuf_delete, both are freed.  But in heapbuf_close, only the handle is freed.
The object pointer is not freed and caused a memory leak.  This patch adds a
call to free the object.

In the function notify_ducatidrv_unregister_event, it finds the event listener
and deletes the list element containing that listener, but did not free the
listener object itself, which was kmalloced in notify_ducatidrv_register_event.
The listener is now being freed.

sysmgr_destroy was not cleaning up platform_mem.  As a result, memory allocated
by platform_mem_setup was not freed by platform_mem_destroy.  This has been
fixed.  Also, platform_mem_destroy was incorrectly freeing the allocated gate
handle.  It now frees it correctly.

The memory alignment was not done properly in proc4430_map.  It was not
being aligned to the size of all pages needed to cover the reserved
area.  As a result, not all of it was reserved.  This has been fixed and

This is a patch for near-term to enable MM to validate non-Tiler buffers.
This patch  maps the SW DMM region at 0x80000000 and of size 4MB into

platform_setup function. platform_override_config function is updated

This patch incorporates a number of bug fixes from the Syslink
2.00.00.12 drop. The following is the summary of changes.

1. sharedregion:
	- sharedregion_remove() is corrected to remove the
		sharedregion entry from the desired processor table.
2. platform_mem:
	- fixed memory leaks.
3. nameserver_remotenotify:
	- an atomic_t variable is added to maintain reference counting
		and the state of the module.
	- nameserver_get_local searches directly copy the value into the
		sharedmemory request buffer.
	- additional error checking is added.
4. messageq:
	- Number of priority queues definition moved from messageq source
		code to messageq header file, and is now also used by
		the messageq_transportshm module.
	- messageqq_transportshm module state object also keeps track of
		the individual messageq_transportshm instances created.
5. listmp_sharedmemory:
	- listmp_sharedmemory_open return value can come from nameserver,
		and so is checked against only a negative value for failure
	- sharedregion value is added into the nameserver database rather
		than the absolute sharedaddr.
	- minor changes in variable names.
6. heapbuf:
	- additional checks were added for valid sharedregion ptrs.
	- heapbuf_open return value can come from nameserver, and so
		is checked against only a negative value for failure.
	- minor changes in variable names.
7. gatepeterson:
	- minor changes in gatepeterson module. This module is currently
		missing the gatespinlock for interrupt context protection.
	- additional checks were added for valid sharedregion ptrs.

This patch provides the following functionality:
	1. Virt_To_Phys - Given a Co-processor's virtual
	address, the pages that are mapped are retured
	in the buffer passed by the user.
	2. Given a Chiron's virtual address, maps to
	Ducati virtual address. This is a hack for now
	to address Tiler memory until the dynmamic memory
	allocation for Tiler is supported.

	This patch also fixed bug in memory unmap function
	using iommu for Super and Large page cases.
