Commit 2a95ea6c ("procfs: do not overflow get_{idle,iowait}_time for nohz") did not take into account that one some architectures jiffies and cputime use different units. This causes get_idle_time() to return numbers in the wrong units, making the idle time fields in /proc/stat wrong. Instead of converting the usec value returned by get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function usecs_to_cputime64 to convert it to the correct unit of cputime64_t.

commit 8aacc9f5 ("mm/mempolicy.c: fix pgoff in mbind vma merge") is the slightly incorrect fix. Why? Think following case. 1. map 4 pages of a file at offset 0 [0123] 2. map 2 pages just after the first mapping of the same file but with page offset 2 [0123][23] 3. mbind() 2 pages from the first mapping at offset 2. mbind_range() should treat new vma is, [0123][23] |23| mbind vma but it does [0123][23] |01| mbind vma Oops. then, it makes wrong vma merge and splitting ([01][0123] or similar).

Commit 5e081591 "block: warn if tag is greater than real_max_depth" cleaned up blk_queue_end_tag() to warn when the tag is truly invalid (greater than real_max_depth). However, it changed behavior in the tag < max_depth case to not end the request. Leading to triggering of BUG_ON(blk_queued_rq(rq)) in the request completion path: http://marc.info/?l=linux-kernel&m=132204370518629&w=2 In order to allow blk_queue_resize_tags() to shrink the tag space blk_queue_end_tag() must always complete tags with a value less than real_max_depth regardless of the current max_depth. The comment about "handling the shrink case" seems to be what prompted changes in this space, so remove it and BUG on all invalid tags (made even simpler by Matthew's suggestion to use an unsigned compare).

Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver The previous patch breaks reset watchdog behaviour on the older hardware. It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or 6300ESB) is preserved and that the behaviour for newer hardware is changed. We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN bit in the SMI_EN register. So the new behaviour becomes: turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog. turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1 (ICHO till ICH5 + 6300ESB only) turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.

Bruce Fields notes that commit 778fc546 ("locks: fix tracking of inprogress lease breaks") introduced a possible error pointer dereference on failure to allocate memory. locks_conflict() will dereference the passed-in new lease lock structure that may be an error pointer. This means an open (without O_NONBLOCK set) on a file with a lease applied (generally only done when Samba or nfsd (with v4) is running) could crash if a kmalloc() fails. So instead of playing games with IS_ERROR() all over the place, just check the allocation failure early. That makes the code more straightforward, and avoids this possible bad pointer dereference.

Unlike all of the other cpuid bits, the TSC deadline timer bit is set unconditionally, regardless of what userspace wants. This is broken in several ways: - if userspace doesn't use KVM_CREATE_IRQCHIP, and doesn't emulate the TSC deadline timer feature, a guest that uses the feature will break - live migration to older host kernels that don't support the TSC deadline timer will cause the feature to be pulled from under the guest's feet; breaking it - guests that are broken wrt the feature will fail. Fix by not enabling the feature automatically; instead report it to userspace. Because the feature depends on KVM_CREATE_IRQCHIP, which we cannot guarantee will be called, we expose it via a KVM_CAP_TSC_DEADLINE_TIMER and not KVM_GET_SUPPORTED_CPUID. Fixes the Illumos guest kernel, which uses the TSC deadline timer feature.

Only allow KVM device assignment to attach to devices which: - Are not bridges - Have BAR resources (assume others are special devices) - The user has permissions to use Assigning a bridge is a configuration error, it's not supported, and typically doesn't result in the behavior the user is expecting anyway. Devices without BAR resources are typically chipset components that also don't have host drivers. We don't want users to hold such devices captive or cause system problems by fencing them off into an iommu domain. We determine "permission to use" by testing whether the user has access to the PCI sysfs resource files. By default a normal user will not have access to these files, so it provides a good indication that an administration agent has granted the user access to the device.
