adf66602a0 8052172: Evacuation failure handling in G1 does not evacuate all objects if -XX:-G1DeferredRSUpdate is set
Remove -XX:-G1DeferredRSUpdate functionality as it is racy. During evacuation failure handling, threads where evacuation failure handling occurred may try to add remembered sets to regions which remembered sets are currently being scanned. The iterator to handle the remembered set scan does not support addition of entries during scan and so may skip valid references.

344be39551 8054808: Bitmap verification sometimes fails after Full GC aborts concurrent mark
The verification code that checked whether no bitmap mark had been found re-read HeapRegion::end() after the check on the bitmap. Concurrent humongous object allocation could have changed HeapRegion::end() in the meantime. Fix this by using the actual end of the region instead of HeapRegion::end() for comparison.

7fe4686591 8055525: Bigapp weblogic+medrec fails to startup after JDK-8038423
If large pages are enabled and configured in Linux, the VM always pre-commits the entire space. The VM fails verification of the commit of the initial heap because some internal data structure marked all memory pages of the heap as committed during initialization. This makes the code think that we attempted a double-commit during first allocation of the heap. Remove the initial marking of memory pages of the heap to committed.
