  "message": "x86: vmm: Disable IRQs when mucking with pcpu GPCs\n\nvmx_clear_vmcs() is called from a few places, and interrupts could be on.\nWe could have had a race where we start to clear, then get interrupted by\nan IPI/IKM that mucks with the per-cpu GPC state.  Then the interrupt\nreturns.  I didn\u0027t see this one - we\u0027d probably need at least one VM\nbouncing around the cores to get this bug.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
