      Description

      After the fix for JDK-8139864, the fixes for JDK-8140582 and JDK-8143153 are no longer needed. The following can once again be used for MIN_STACK_SHADOW_PAGES:

      #define MIN_STACK_SHADOW_PAGES DEFAULT_STACK_SHADOW_PAGES

      Not that this is also a correctness issue. By having MIN_STACK_SHADOW_PAGES be less than DEFAULT_STACK_SHADOW_PAGES as it currently is, there is the potential for the user to set StackShadowPages to a size that will result in overwriting the end of the stack.
