58 so. If we mess that up even slightly, we crash.
60 So when we have a secondary entry, already in kernel mode, we *must
61 not* use SWAPGS blindly - nor must we forget doing a SWAPGS when it's
87 If we are at an interrupt or user-trap/gate-alike boundary then we can
89 whether SWAPGS was already done: if we see that we are a secondary
90 entry interrupting kernel mode execution, then we know that the GS
91 base has already been switched. If it says that we interrupted
92 user-space execution then we must do the SWAPGS.
94 But if we are in an NMI/MCE/DEBUG/whatever super-atomic entry context,
96 stack but before we executed SWAPGS, then the only safe way to check
108 that absolutely need the more expensive check for the GS base - and we
