I'm not sure why it was doing this, and I'm not sure I _want_ to know why. But calling it NETIF_F_DYNALLOC doesn't change the fact that the kernel believes it to be NETIF_F_IPV6_CSUM, and that IPv6 communication is hence buggered.

2007-11-15dirty page balancing: Get rid of broken unmapped_ratio logicLinus Torvalds
This code harks back to the days when we didn't count dirty mapped pages, which led us to try to balance the number of dirty unmapped pages by how much unmapped memory there was in the system. That makes no sense any more, since now the dirty counts include the mapped pages. Not to mention that the math doesn't work with HIGHMEM machines anyway, and causes the unmapped_ratio to potentially turn negative (which we do catch thanks to clamping it at a minimum value, but I mention that as an indication of how broken the code is). The code also was written at a time when the default dirty ratio was much larger, and the unmapped_ratio logic effectively capped that large dirty ratio a bit. Again, we've since lowered the dirty ratio rather aggressively, further lessening the point of that code.

2007-11-15[MIPS] irq_cpu: use handle_percpu_irq handler to avoid dropping interrupts.Ralf Baechle
This matters to any sort of device that is wired to one of the CPU interrupt pins on an SMP system. Typically the scenario is most easily triggered with the count/compare timer interrupt where the same interrupt number and thus irq_desc is used on each processor. CPU A CPU B do_IRQ() generic_handle_irq() handle_level_irq() spin_lock(desc_lock) set IRQ_INPROGRESS spin_unlock(desc_lock) do_IRQ() generic_handle_irq() handle_level_irq() spin_lock(desc_lock) IRQ_INPROGRESS set => bail out spin_lock(desc_lock) clear IRQ_INPROGRESS spin_unlock(desc_lock) In case of the cp0 compare interrupt this means the interrupt will be acked and not handled or re-armed on CPU b, so there won't be any timer interrupt until the count register wraps around. With kernels 2.6.20 ... 2.6.23 we usually were lucky that things were just working right on VSMP because the count registers are synchronized on bootup so it takes something that disables interrupts for a long time on one processor to trigger this one. For scenarios where an interrupt is multicasted or broadcasted over several CPUs the existing code was safe and the fix will break it. There is no way to know in the interrupt controller code because it is abstracted from the platform code. I think we do not have such a setup currently, so this should be ok.

2007-11-15[MIPS] Sibyte: Stop timers before programming next even.Ralf Baechle
We have no guarantee by the generic time code that the timer is stopped when the ->next_event method is called. Modifying the Timer Initial Count register while the timer is enabled has UNPREDICTABLE effect according to the BCM1250/BCM1125/BCM1125H User Manual. So stop the timer before reprogramming. This is a paranoia fix; no ill effects have been observed previously. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-15[MIPS] Sibyte: Increase minimum oneshot timer interval to two ticks.Ralf Baechle
For the old minimum of a single tick a value of zero would be programmed into the init value register which in the BCM1250/BCM1125/BCM1125H User Manual in the Timer Special Cases section is documented to have UNPREDICTABLE effect. Observable sympthoms of this bug were hangs of several seconds on the console during bootup and later if both dyntick and highres timer options were activated. In theory contiguous mode of the timers is also affected but in an act of hopeless lack of realism I'll assume nobody will ever configure a KERNEL for HZ > 500kHz but if so I leave that to evolution to sort out.

2007-11-15[MIPS] Fix shadow register support.Ralf Baechle
Shadow register support would not possibly have worked on multicore systems. The support code for it was also depending not on MIPS R2 but VSMP or SMTC kernels even though it makes perfect sense with UP kernels. SR sets are a scarce resource and the expected usage pattern is that users actually hardcode the register set numbers in their code. So fix the allocator by ditching it. Move the remaining CPU probe bits into the generic CPU probe. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-15[MIPS] Change get_cycles to always return 0.Ralf Baechle
This avoids us executing an mfc0 c0_count instruction on processors which don't have but also on certain R4000 and R4400 versions where reading from the count register just in the very moment when its value equals c0_compare will result in the timer interrupt getting lost. There is still a number of users of get_cycles remaining outside the arch code: crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); drivers/char/hangcheck-timer.c: return get_cycles(); drivers/char/hangcheck-timer.c: printk("Hangcheck: Using get_cycles().\n"); drivers/char/random.c: sample.cycles = get_cycles(); drivers/input/joystick/analog.c:#define GET_TIME(x) do { x = get_cycles(); } include/linux/arcdevice.h: _x = get_cycles(); \ include/linux/arcdevice.h: _y = get_cycles(); \ mm/slub.c: if (!s->defrag_ratio || get_cycles() % 1024 > s->defrag_ratio) mm/slub.c: p += 64 + (get_cycles() & 0xff) * sizeof(void *); Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-11-15sched: fix __set_task_cpu() SMP raceDmitry Adamushko
Grant Wilson has reported rare SCHED_FAIR_USER crashes on his quad-core system, which crashes can only be explained via runqueue corruption. there is a narrow SMP race in __set_task_cpu(): after ->cpu is set up to a new value, task_rq_lock(p, ...) can be successfuly executed on another CPU. We must ensure that updates of per-task data have been completed by this moment. this bug has been hiding in the Linux scheduler for an eternity (we never had any explicit barrier for task->cpu in set_task_cpu() - so the bug was introduced in 2.5.1), but only became visible via set_task_cfs_rq() being accidentally put after the task->cpu update. It also probably needs a sufficiently out-of-order CPU to trigger.

2007-11-15sched: fix SCHED_FIFO tasks & FAIR_GROUP_SCHEDOleg Nesterov
Suppose that the SCHED_FIFO task does switch_uid(new_user); Now, p->se.cfs_rq and p->se.parent both point into the old user_struct->tg because sched_move_task() doesn't call set_task_cfs_rq() for !fair_sched_class case. Suppose that old user_struct/task_group is freed/reused, and the task does sched_setscheduler(SCHED_NORMAL); __setscheduler() sets fair_sched_class, but doesn't update ->se.cfs_rq/parent which point to the freed memory. This means that check_preempt_wakeup() doing while (!is_same_group(se, pse)) { se = parent_entity(se); pse = parent_entity(pse); } may OOPS in a similar way if rq->curr or p did something like above. Perhaps we need something like the patch below, note that __setscheduler() can't do set_task_cfs_rq(). Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2007-11-15sched: fix accounting of interrupts during guest execution on s390Christian Borntraeger
Currently the scheduler checks for PF_VCPU to decide if this timeslice has to be accounted as guest time. On s390 host interrupts are not disabled during guest execution. This causes theses interrupts to be accounted as guest time if CONFIG_VIRT_CPU_ACCOUNTING is set. Solution is to check if an interrupt triggered account_system_time. As the tick is timer interrupt based, we have to subtract hardirq_offset. I tested the patch on s390 with CONFIG_VIRT_CPU_ACCOUNTING and on x86_64. Seems to work.
