Log:
dtrace: remove unexplained 16MB limitation from dt_alloc/dt_zalloc
The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
$ dtrace -x bufsize=17m -n ...
dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.
