git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull SMP hotplug updates from Thomas Gleixner: "This update is primarily a cleanup of the CPU hotplug locking code. The hotplug locking mechanism is an open coded RWSEM, which allows recursive locking. The main problem with that is the recursive nature as it evades the full lockdep coverage and hides potential deadlocks. The rework replaces the open coded RWSEM with a percpu RWSEM and establishes full lockdep coverage that way. The bulk of the changes fix up recursive locking issues and address the now fully reported potential deadlocks all over the place. Some of these deadlocks have been observed in the RT tree, but on mainline the probability was low enough to hide them away." * 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) cpu/hotplug: Constify attribute_group structures powerpc: Only obtain cpu_hotplug_lock if called by rtasd ARM/hw_breakpoint: Fix possible recursive locking for arch_hw_breakpoint_init cpu/hotplug: Remove unused check_for_tasks() function perf/core: Don't release cred_guard_mutex if not taken cpuhotplug: Link lock stacks for hotplug callbacks acpi/processor: Prevent cpu hotplug deadlock sched: Provide is_percpu_thread() helper cpu/hotplug: Convert hotplug locking to percpu rwsem s390: Prevent hotplug rwsem recursion arm: Prevent hotplug rwsem recursion arm64: Prevent cpu hotplug rwsem recursion kprobes: Cure hotplug lock ordering issues jump_label: Reorder hotplug lock and jump_label_lock perf/tracing/cpuhotplug: Fix locking order ACPI/processor: Use cpu_hotplug_disable() instead of get_online_cpus() PCI: Replace the racy recursion prevention PCI: Use cpu_hotplug_disable() instead of get_online_cpus() perf/x86/intel: Drop get_online_cpus() in intel_snb_check_microcode() x86/perf: Drop EXPORT of perf_check_microcode ...

The problem is documented now and fixed with a microcode update, so we can remove the workaround and just check for the microcode version. If the microcode is not up to date, then the TSC deadline timer is disabled. If the borkage is fixed by the proper microcode version, then the deadline timer can be used.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 PCI updates from Thomas Gleixner: "This update provides the seperation of x86 PCI accessors from the global PCI lock in the generic PCI config space accessors. The reasons for this are: - x86 has it's own PCI config lock for various reasons, so the accessors have to lock two locks nested. - The ECAM (mmconfig) access to the extended configuration space does not require locking. The existing generic locking causes a massive lock contention when accessing the extended config space of the Uncore facility for performance monitoring. The commit which switched the access to the primary config space over to ECAM mode has been removed from the branch, so the primary config space is still accessed with type1 accessors properly serialized by the x86 internal locking.

(Thomas Gleixner) Aside of consolidating code this is a preparatory change for: - Finalizing the affinity management for multi-queue devices. The main change here is to shut down interrupts which are affine to a outgoing CPU and reenabling them when the CPU comes online again. That avoids moving interrupts pointlessly around and breaking and reestablishing affinities for no value.

This comes with NVMe support as well, so applications can help guide data placement on flash to improve performance, latencies, and write amplification. - A series from Ming, improving and hardening blk-mq support for stopping/starting and quiescing hardware queues. - Two pull requests for NVMe updates.

2017-07-02parisc: Report SIGSEGV instead of SIGBUS when running out of stackHelge Deller
When a process runs out of stack the parisc kernel wrongly faults with SIGBUS instead of the expected SIGSEGV signal. This example shows how the kernel faults: do_page_fault() command='a.out' type=15 address=0xfaac2000 in libc-2.24.so[f8308000+16c000] trap #15: Data TLB miss fault, vm_start = 0xfa2c2000, vm_end = 0xfaac2000 The vma->vm_end value is the first address which does not belong to the vma, so adjust the check to include vma->vm_end to the range for which to send the SIGSEGV signal. This patch unbreaks building the debian libsigsegv package. Cc: stable@vger.kernel.org Signed-off-by: Helge Deller <deller@gmx.de>
2017-07-02parisc: use compat_sys_keyctl()Eric Biggers
Architectures with a compat syscall table must put compat_sys_keyctl() in it, not sys_keyctl(). The parisc architecture was not doing this; fix it.

The reordering fix and the MADDF/MSUBF fix have sat in linux-next for a number of days. The others haven't propagated from my pull tree to linux-next yet but all have survived manual testing and Imagination's automated test system and there are no pending bug reports" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Avoid accidental raw backtrace MIPS: Perform post-DMA cache flushes on systems with MAARs MIPS: Fix IRQ tracing & lockdep when rescheduling MIPS: pm-cps: Drop manual cache-line alignment of ready_count MIPS: math-emu: Handle zero accumulator case in MADDF and MSUBF separately MIPS: head: Reorder instructions missing a delay slot

2017-06-30uapi/linux/a.out.h: don't use deprecated system-specific predefines.Zack Weinberg
uapi/linux/a.out.h uses a number of predefined macros that are deprecated because they're in the application namespace (e.g. '#ifdef linux' instead of '#ifdef __linux__'). This patch either corrects or just removes them if they are not applicable to Linux. The primary reason this is worth bothering to fix, considering how obsolete a.out binary support is, is that the GCC build process considers this such a severe error that it will copy the header into a private directory and change the macro names, which causes future updates to the header to be masked. This header probably doesn't get updated very often anymore, but it is the _only_ uapi header that gets this treatment, so IMHO it is worth patching just to drive that number all the way to zero.
