Patch Name: PHKL_1021

Patch Description:  Correctly and automatically return swap to file system.

    File system swap space could be reserved without being allocated, in
    which case it was not specificaly tagged as being used.  However, the
    return swap to file system functionality only returned tagged space.

    Also, the code path to return swap was not executed by syncer calling
    tsync() on stand-alone systems.

    This patch makes the VM system return both tagged and untagged space,
    and executes the necessary code path for all types of sync'ing.

    This is very similar to PHKL_0804.  The difference is the
    automatic return of swap on stand alone systems, which this patch
    handles and PHKL_0804 did not handle.
