2016-12-23seq_file: reset iterator to first record for zero offsetTomasz Majchrzak1-0/+7
If kernfs file is empty on a first read, successive read operations using the same file descriptor will return no data, even when data is available. Default kernfs 'seq_next' implementation advances iterator position even when next object is not there. Kernfs 'seq_start' for following requests will not return iterator as position is already on the second object. This defect doesn't allow to monitor badblocks sysfs files from MD raid. They are initially empty but if data appears at some stage, userspace is not able to read it.

2016-12-23[iov_iter] fix iterate_all_kinds() on empty iteratorsAl Viro1-29/+26
Problem similar to ones dealt with in "fold checks into iterate_and_advance()" and followups, except that in this case we really want to do nothing when asked for zero-length operation - unlike zero-length iterate_and_advance(), zero-length iterate_all_kinds() has no side effects, and callers are simpler that way. That got exposed when copy_from_iter_full() had been used by tipc, which builds an msghdr with zero payload and (now) feeds it to a primitive based on iterate_all_kinds() instead of iterate_and_advance().

2016-12-19quota: Fix bogus warning in dquot_disable()Jan Kara1-2/+2
dquot_disable() was warning when sb_has_quota_loaded() was true when invalidating page cache for quota files. The thinking behind this warning was that we must have raced with somebody else turning quotas on and this should not happen because all places modifying quota state must hold s_umount exclusively now. However sb_has_quota_loaded() can be also true at this point when we are just suspending quotas on remount read-only. Just restore the behavior to situation before commit c3b004460d77 ("quota: Remove dqonoff_mutex") which introduced the warning. The code in dquot_disable() can be further simplified with the new locking of quota state changes however let's leave that to a separate commit that can get more testing exposure.

2016-12-19rtc: mcp795: fix month write resetting date to 1.Emil Bartczak1-5/+81
According to Microchip errata some combinations of date and month values may result in the date being reset to 1, even if the date is also written with the month (for example 31-07 or 31-08). As a workaround avoid writing date and month values within the same Write command. Instead, terminate the Write command after loading the date and begin a new command to write the month. In addition, disable the oscillator before loading the new values. This is done by ensuring both the ST and EXTOSC bits are cleared and waiting for the OSCON bit to clear.

As for this pull request the bulk of it has been in -next for several releases leading to one late fix being added (commit 868f036fee4b ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It has received a build success notification from the 0day-kbuild robot and passes the latest libnvdimm unit tests. Summary: - Dynamic label support: To date namespace label support has been limited to disambiguating cases where PMEM (direct load/store) and BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. - Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. - Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions. In particular this enables userspace tooling to generically size memory mapping and i/o operations. Prevent userspace from growing assumptions / dependencies about the parent device topology for a dax region.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "This is the last functional update from the tip tree for 4.10. It got delayed due to a newly reported and anlyzed variant of BIOS bug and the resulting wreckage: - Seperation of TSC being marked realiable and the fact that the platform provides the TSC frequency via CPUID/MSRs and making use for it for GOLDMONT. - TSC adjust MSR validation and sanitizing: The TSC adjust MSR contains the offset to the hardware counter. The sum of the adjust MSR and the counter is the TSC value which is read via RDTSC. On at least two machines from different vendors the BIOS sets the TSC adjust MSR to negative values. This happens on cold and warm boot. While on cold boot the offset is a few milliseconds, on warm boot it basically compensates the power on time of the system. The BIOSes are not even using the adjust MSR to set all CPUs in the package to the same offset. The offsets are different which renders the TSC unusable, What's worse is that the TSC deadline timer has a HW feature^Wbug. It malfunctions when the TSC adjust value is negative or greater equal 0x80000000 resulting in silent boot failures, hard lockups or non firing timers. This looks like some hardware internal 32/64bit issue with a sign extension problem. Intel has been silent so far on the issue. The update contains sanity checks and keeps the adjust register within working limits and in sync on the package.

2016-12-18x86/tsc: Limit the adjust value furtherThomas Gleixner1-5/+16
Adjust value 0x80000000 and other values larger than that render the TSC deadline timer disfunctional. We have not yet any information about this from Intel, but experimentation clearly proves that this is a 32/64 bit and sign extension issue. If adjust values larger than that are actually required, which might be the case for physical CPU hotplug, then we need to disable the deadline timer on the affected package/CPUs and use the local APIC timer instead. That requires some surgery in the APIC setup code, so we just limit the ADJUST register value into the known to work range for now and revisit this when Intel comes forth with proper information.

The build of sparc allmodconfig fails with the error: "of_irq_to_resource" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined! of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can safely use #if defined(CONFIG_OF_IRQ) in the code.
