+Subject: [PATCH] Avoid save/restoring AMX registers to avoid a SPR erratum
+
+Intel SPR erratum SPR4 says that if you trip into a vmexit while
+doing FPU save/restore, your AMX register state might misbehave...
+and by misbehave, I mean save all zeroes incorrectly, leading to
+explosions if you restore it.
+
+Since we're not using AMX for anything, the simple way to avoid
+this is to just not save/restore those when we do anything, since
+we're killing preemption of any sort across our save/restores.
+
+If we ever decide to use AMX, it's not clear that we have any
+way to mitigate this, on Linux...but I am not an expert.
