* hwmon: (lm77) Do not preserve hysteresis when updating critical temp limitGuenter Roeck2014-05-222-8/+18
| | | | | | | | | | | | | Updating the hysteresis value when updating the critical temperature limit was following the rule of 'least surprise'. However, it had the undesirable side effect of changing the hysteresis for all other attributes, which defeats the purpose of least surprise. In addition, it could result in invalid hysteresis values if the resulting hysteresis was too large. In such cases the resulting hysteresis ended up changed anyway, which again defeats the purpose. So drop that code and document the new behavior. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

One from Anton fixes a nasty regression I introduced when trying to fix a loss of irq_work whose consequences is that we can completely lose timer interrupts on a CPU... not pretty. The other one is a change to our PCIe reset hook to use a firmware call instead of direct config space accesses to trigger a fundamental reset on the root port. This is necessary so that the FW gets a chance to disable the link down error monitoring, which would otherwise trip and cause subsequent fatal EEH error" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: irq work racing with timer interrupt can result in timer interrupt hang powerpc/powernv: Reset root port in firmware

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I am seeing an issue where a CPU running perf eventually hangs. Traces show timer interrupts happening every 4 seconds even when a userspace task is running on the CPU. /proc/timer_list also shows pending hrtimers have not run in over an hour, including the scheduler. Looking closer, decrementers_next_tb is getting set to 0xffffffffffffffff, and at that point we will never take a timer interrupt again. In __timer_interrupt() we set decrementers_next_tb to 0xffffffffffffffff and rely on ->event_handler to update it: *next_tb = ~(u64)0; if (evt->event_handler) evt->event_handler(evt); In this case ->event_handler is hrtimer_interrupt. This will eventually call back through the clockevents code with the next event to be programmed: static int decrementer_set_next_event(unsigned long evt, struct clock_event_device *dev) { /* Don't adjust the decrementer if some irq work is pending */ if (test_irq_work_pending()) return 0; __get_cpu_var(decrementers_next_tb) = get_tb_or_rtc() + evt; If irq work came in between these two points, we will return before updating decrementers_next_tb and we never process a timer interrupt again. This looks to have been introduced by 0215f7d8c53f (powerpc: Fix races with irq_work). Fix it by removing the early exit and relying on code later on in the function to force an early decrementer: /* We may have raced with new irq work */ if (test_irq_work_pending()) set_dec(1); Signed-off-by: Anton Blanchard <anton@samba.org> Cc: stable@vger.kernel.org # 3.14+ Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | Resetting root port has more stuff to do than that for PCIe switch ports and we should have resetting root port done in firmware instead of the kernel itself.

The bug report can be found here: https://github.com/zfsonlinux/spl/issues/241 http://tracker.ceph.com/issues/7790 The reason is that ZFS will send pages with page_count 0 into rbd, which in turns send them to tcp_sendpage. However, tcp_sendpage cannot deal with page_count 0, as it will do get_page and put_page, and erroneously free the page. This type of issue has been noted before, and handled in iscsi, drbd, etc. So, rbd should also handle this. This fix address this issue by fall back to slower sendmsg when page_count 0 detected.

IOMMU does not translate the access to the exclusion range from the device. The device is specified by input argument 'devid'. But 'devid' is not passed to the actual set function set_dev_entry_bit(), instead 'm->devid' is passed. 'm->devid' does not specify the exact device which needs enable the exclusion range. 'm->devid' represents DeviceID field of IVMD, which has different meaning depends on IVMD type. The caller init_exclusion_range() sets 'devid' for ONE device. When m->type is equal to ACPI_IVMD_TYPE_ALL or ACPI_IVMD_TYPE_RANGE, 'm->devid' is not equal to 'devid'. This patch fixes 'm->devid' to 'devid'.
