x86/mm/KASLR: Reduce randomization granularity for 5-level paging to 1GB
The current randomization granularity of 5-level is 512 GB. The mapping of the real mode trampoline has been reduced to one PUD entry, so there is no restriction anymore. Reduce the granularity to 1GB for 5-level paging mode which allows better randomization.
