      "message": "x86: FIFO ticket spinlocks\n\nIntroduce ticket lock spinlocks for x86 which are FIFO. The implementation\nis described in the comments. The straight-line lock/unlock instruction\nsequence is slightly slower than the dec based locks on modern x86 CPUs,\nhowever the difference is quite small on Core2 and Opteron when working out of\ncache, and becomes almost insignificant even on P4 when the lock misses cache.\ntrylock is more significantly slower, but they are relatively rare.\n\nOn an 8 core (2 socket) Opteron, spinlock unfairness is extremely noticable,\nwith a userspace test having a difference of up to 2x runtime per thread, and\nsome threads are starved or \"unfairly\" granted the lock up to 1 000 000 (!)\ntimes. After this patch, all threads appear to finish at exactly the same\ntime.\n\nThe memory ordering of the lock does conform to x86 standards, and the\nimplementation has been reviewed by Intel and AMD engineers.\n\nThe algorithm also tells us how many CPUs are contending the lock, so\nlockbreak becomes trivial and we no longer have to waste 4 bytes per\nspinlock for it.\n\nAfter this, we can no longer spin on any locks with preempt enabled\nand cannot reenable interrupts when spinning on an irq safe lock, because\nat that point we have already taken a ticket and the would deadlock if\nthe same CPU tries to take the lock again.  These are questionable anyway:\nif the lock happens to be called under a preempt or interrupt disabled section,\nthen it will just have the same latency problems. The real fix is to keep\ncritical sections short, and ensure locks are reasonably fair (which this\npatch does).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
