Revision 18bc7bd523e0fc5be8d76bf84bde733a97a8c375 authored by Andy Lutomirski on 10 August 2016, 09:29:14 UTC, committed by Ingo Molnar on 11 August 2016, 09:15:00 UTC
The initialization process for trampoline_cr4_features and mmu_cr4_features was confusing. The intent is for mmu_cr4_features and *trampoline_cr4_features to stay in sync, but trampoline_cr4_features is NULL until setup_real_mode() runs. The old code synchronized *trampoline_cr4_features *twice*, once in setup_real_mode() and once in setup_arch(). It also initialized mmu_cr4_features in setup_real_mode(), which causes the actual value of mmu_cr4_features to potentially depend on when setup_real_mode() is called. With this patch, mmu_cr4_features is initialized directly in setup_arch(), and *trampoline_cr4_features is synchronized to mmu_cr4_features when the trampoline is set up. After this patch, it should be safe to defer setup_real_mode().
