  "message": "preempt: Track NMI nesting to separate per-CPU counter\n\nMove NMI nesting tracking from the preempt_count bits to a separate per-CPU\ncounter (nmi_nesting). This is to free up the NMI bits in the preempt_count,\nallowing those bits to be repurposed for other uses.  This also has the benefit\nof tracking more than 16-levels deep if there is ever a need.\n\nReduce multiple bits in preempt_count for NMI tracking. Reduce NMI_BITS\nfrom 3 to 1, using it only to detect if we\u0027re in an NMI.\n\nSuggested-by: Boqun Feng \u003cboqun.feng@gmail.com\u003e\nSigned-off-by: Joel Fernandes \u003cjoelaf@google.com\u003e\n",
