IRQ_MOVE_PCNTXT was there\nwhen we eventually submitted the patch upstream. But, looks like I did a\nblind rebasing instead of using IRQ_MOVE_PCNTXT in hpet MSI code.\n\nBelow patch fixes this. i.e., revert commit 932775a4ab622e3c99bd59f14cc\nand add PCNTXT to HPET MSI setup. Also removes copying of desc-\u003eaffinity\nin generic code as set_affinity routines are doing it internally.\n\nReported-by: \"Eric W.

The problem stems from a misguided attempt to provide a\nwork-around for jiffies-counter failure. This work-around uses a per-CPU\nn_rcu_pending counter, which is incremented on each call to rcu_pending(),\nwhich in turn is called from each scheduling-clock interrupt. Each CPU\nthen treats this counter as a surrogate for the jiffies counter, so\nthat if the jiffies counter fails to advance, the per-CPU n_rcu_pending\ncounter will cause RCU to invoke force_quiescent_state(), which in turn\nwill (among other things) send resched IPIs to CPUs that have thus far\nfailed to pass through an RCU quiescent state.\n\nUnfortunately, each CPU resets only its own counter after sending a\nbatch of IPIs. This means that the other CPUs will also (needlessly)\nsend -another- round of IPIs, for a full N-squared set of IPIs in the\nworst case every three scheduler-clock ticks until the grace period\nfinally ends. It is not reasonable for a given CPU to reset each and\nevery n_rcu_pending for all the other CPUs, so this patch instead simply\ndisables the jiffies-counter \"training wheels\", thus eliminating the\nexcessive IPIs.\n\nNote that the jiffies-counter IPIs do not have this problem due to\nthe fact that the jiffies counter is global, so that the CPU sending\nthe IPIs can easily reset things, thus preventing the other CPUs from\nsending redundant IPIs.\n\nNote also that the n_rcu_pending counter remains, as it will continue to\nbe used for tracing. It may also see use to update the jiffies counter,\nshould an appropriate kick-the-jiffies-counter API appear.\n\nLocated-by: Anton Blanchard \u003canton@au1.ibm.com\u003e\nTested-by: Anton Blanchard \u003canton@au1.ibm.com\u003e\nSigned-off-by: Paul E.
