76cc94fb99 2178143: JVM crashes if the number of bound CPUs changed during runtime 
Supply a new flag -XX:+AssumeMP to workaround the problem. With the flag is turned on, assume VM run on MP platform so is_MP() will return true that sync calls will not skip away.

bb5bd507d7 7112912: Message "Error occurred during initialization of VM" on boxes with lots of RAM 
Ergonomics now also takes available virtual memory into account when deciding for a heap size. The helper method to determine the maximum allocatable memory block now uses the appropriate OS specific calls to retrieve available virtual memory for the java process. In 32 bit environments this method now also searches for the maximum actually reservable amount of memory. Merge previously separate implementations for Linux/BSD/Solaris into a single method.
