Sorry, I don't really understand. The filler objects are needed to
fix "8138681: Runtime.getFreeMemory() reports wrong value after
humongous allocation."<br>
<br>
<br>
Thanks,<br>

Could be always just set top as you've done for the case where
there<br>
isn't room for a filler object at the end of a humongous
region? And<br>
never use a filler object there?<br>

After offline discussions with Mikael I have updated the webrev

Please review the following patch that fixes the case where we
allocate a humongous object, and where the space left in the
humongous region cannot fit a filler object. In that case we
must set top of the last heap region to the end of the object.
Also, there is a new jtreg test which crashes the JVM before
this patch, and works fine after. <br>
