Last change on this file since 87477 was 87472, checked in by vboxsync, 4 years ago

VMM/HMVMX: Moving more stuff to HMR0PERVCPU. Created VMXVMCSINFOSHARED for some bits we seem to need to share with ring-3 (real mode, last branch stuff), the remaining VMXVMCSINFO structure is now ring-0 only. bugref:9217

1425 * @remarks With spectre mitigations and the usual need for speed (/ micro
1426 * optimizations), we have a bunch of variations of this code depending
1427 * on a few precoditions. In release builds, the code is entirely
1428 * without conditionals. Debug builds have a couple of assertions that
1429 * shouldn't ever be triggered.
