Name:This can be used from process context to figure out what the value of* CR3 is without needing to do a (slow) __read_cr3().* It's intended to be used for code like KVM that sneakily changes CR3* and needs to restore it. It needs to be used very carefully.
Proto:static inline unsigned long __get_current_cr3_fast(void)
Type:unsigned long
Parameter:Nothing
| 352 | cr3 = build_cr3(pgd, Operations with implied preemption/interrupt protection. These* operations can be used without worrying about preemption or interrupt.(loaded_mm_asid)) |
| 356 | VM_WARN_ON(in_nmi() || preemptible()) |
| 358 | VM_BUG_ON(cr3 != Careful! CR3 contains more than just an address. You probably want* read_cr3_pa() instead.) |
| 359 | Return cr3 |
