Pull parallel filesystem directory handling update from Al Viro. This is the main parallel directory work by Al that makes the vfs layer able to do lookup and readdir in parallel within a single directory. That's a big change, since this used to be all protected by the directory inode mutex. The inode mutex is replaced by an rwsem, and serialization of lookups of a single name is done by a "in-progress" dentry marker. The series begins with xattr cleanups, and then ends with switching filesystems over to actually doing the readdir in parallel (switching to the "iterate_shared()" that only takes the read lock). A more detailed explanation of the process from Al Viro: "The xattr work starts with some acl fixes, then switches ->getxattr to passing inode and dentry separately. This is the point where the things start to get tricky - that got merged into the very beginning of the -rc3-based #work.lookups, to allow untangling the security_d_instantiate() mess. The xattr work itself proceeds to switch a lot of filesystems to generic_...xattr(); no complications there. After that initial xattr work, the series then does the following: - untangle security_d_instantiate() - convert a bunch of open-coded lookup_one_len_unlocked() to calls of that thing; one such place (in overlayfs) actually yields a trivial conflict with overlayfs fixes later in the cycle - overlayfs ended up switching to a variant of lookup_one_len_unlocked() sans the permission checks. I would've dropped that commit (it gets overridden on merge from #ovl-fixes in #for-next; proper resolution is to use the variant in mainline fs/overlayfs/super.c), but I didn't want to rebase the damn thing - it was fairly late in the cycle... - some filesystems had managed to depend on lookup/lookup exclusion for *fs-internal* data structures in a way that would break if we relaxed the VFS exclusion. Fixing hadn't been hard, fortunately. - core of that series - parallel lookup machinery, replacing ->i_mutex with rwsem, making lookup_slow() take it only shared. At that point lookups happen in parallel; lookups on the same name wait for the in-progress one to be done with that dentry. Surprisingly little code, at that - almost all of it is in fs/dcache.c, with fs/namei.c changes limited to lookup_slow() - making it use the new primitive and actually switching to locking shared. - parallel readdir stuff - first of all, we provide the exclusion on per-struct file basis, same as we do for read() vs lseek() for regular files. That takes care of most of the needed exclusion in readdir/readdir; however, these guys are trickier than lookups, so I went for switching them one-by-one. To do that, a new method '->iterate_shared()' is added and filesystems are switched to it as they are either confirmed to be OK with shared lock on directory or fixed to be OK with that. I hope to kill the original method come next cycle (almost all in-tree filesystems are switched already), but it's still not quite finished. - several filesystems get switched to parallel readdir. The interesting part here is dealing with dcache preseeding by readdir; that needs minor adjustment to be safe with directory locked only shared. Most of the filesystems doing that got switched to in those commits. Important exception: NFS. Turns out that NFS folks, with their, er, insistence on VFS getting the fuck out of the way of the Smart Filesystem Code That Knows How And What To Lock(tm) have grown the locking of their own. They had their own homegrown rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink is the reader there). Of course, with VFS getting the fuck out of the way, as requested, the actual smarts of the smart filesystem code etc. had become exposed... - do_last/lookup_open/atomic_open cleanups. As the result, open() without O_CREAT locks the directory only shared. Including the ->atomic_open() case. Backmerge from #for-linus in the middle of that - atomic_open() fix got brought in. - then comes NFS switch to saner (VFS-based ;-) locking, killing the homegrown "lookup and readdir are writers" kinda-sorta rwsem. All exclusion for sillyunlink/lookup is done by the parallel lookups mechanism. Exclusion between sillyunlink and rmdir is a real rwsem now - rmdir being the writer. Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel now. - the rest of the series consists of switching a lot of filesystems to parallel readdir; in a lot of cases ->llseek() gets simplified as well. One backmerge in there (again, #for-linus - rockridge fix)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (74 commits) ext4: switch to ->iterate_shared() hfs: switch to ->iterate_shared() hfsplus: switch to ->iterate_shared() hostfs: switch to ->iterate_shared() hpfs: switch to ->iterate_shared() hpfs: handle allocation failures in hpfs_add_pos() gfs2: switch to ->iterate_shared() f2fs: switch to ->iterate_shared() afs: switch to ->iterate_shared() befs: switch to ->iterate_shared() befs: constify stuff a bit isofs: switch to ->iterate_shared() get_acorn_filename(): deobfuscate a bit btrfs: switch to ->iterate_shared() logfs: no need to lock directory in lseek switch ecryptfs to ->iterate_shared 9p: switch to ->iterate_shared() fat: switch to ->iterate_shared() romfs, squashfs: switch to ->iterate_shared() more trivial ->iterate_shared conversions ...

But looking closer into it, I found that the right settings could bypass the checks and crash the kernel. Luckily, this is only accessible by root. The first fix is to convert all the variables into long, such that we don't get into issues between 32 bit variables being assigned 64 bit ones. This fixes the RB_WARN_ON() triggering. The next fix is to get rid of a duplicate DIV_ROUND_UP() that when called twice with the right value, can cause a kernel crash. The first DIV_ROUND_UP() is to normalize the input and it is checked against the minimum allowable value. But then DIV_ROUND_UP() is called again, which can overflow due to the (a + b - 1)/b, logic. The first called upped the value, the second can overflow (with the +b part). The second call to DIV_ROUND_UP() came in via a second change a while ago and the code is cleaned up to remove it" * tag 'trace-fixes-v4.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Prevent overflow of size in ring_buffer_resize() ring-buffer: Use long for nr_pages to avoid overflow failures

Pull power management updates from Rafael Wysocki: "The majority of changes go into the cpufreq subsystem this time. To me, quite obviously, the biggest ticket item is the new "schedutil" governor. Interestingly enough, it's the first new cpufreq governor since the beginning of the git era (except for some out-of-the-tree ones). There are two main differences between it and the existing governors. First, it uses the information provided by the scheduler directly for making its decisions, so it doesn't have to track anything by itself. Second, it can invoke drivers (supporting that feature) to adjust CPU performance right away without having to spawn work items to be executed in process context or similar. Currently, the acpi-cpufreq driver is the only one supporting that mode of operation, but then it is used on a large number of systems. The "schedutil" governor as included here is very simple and mostly regarded as a foundation for future work on the integration of the scheduler with CPU power management (in fact, there is work in progress on top of it already). Nevertheless it works and the preliminary results obtained with it are encouraging. There also is some consolidation of CPU frequency management for ARM platforms that can add their machine IDs the the new stub dt-platdev driver now and that will take care of creating the requisite platform device for cpufreq-dt, so it is not necessary to do that in platform code any more. Several ARM platforms are switched over to using this generic mechanism. In addition to that, the intel_pstate driver is now going to respect CPU frequency limits set by the platform firmware (or a BMC) and provided via the ACPI _PPC object. The devfreq subsystem is getting a new "passive" governor for SoCs subsystems that will depend on somebody else to manage their voltage rails and its support for Samsung Exynos SoCs is consolidated. The rest is support for new hardware (Intel Broxton support in intel_idle for one example), bug fixes, optimizations and cleanups in a number of places. Specifics: - New cpufreq "schedutil" governor (making decisions based on CPU utilization information provided by the scheduler and capable of switching CPU frequencies right away if the underlying driver supports that) and support for fast frequency switching in the acpi-cpufreq driver (Rafael Wysocki) - Consolidation of CPU frequency management on ARM platforms allowing them to get rid of some platform-specific boilerplate code if they are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao, Marc Gonzalez) - Support for ACPI _PPC and CPU frequency limits in the intel_pstate driver (Srinivas Pandruvada) - Fixes and cleanups in the cpufreq core and generic governor code (Rafael Wysocki, Sai Gurrappadi) - intel_pstate driver optimizations and cleanups (Rafael Wysocki, Philippe Longepe, Chen Yu, Joe Perches) - cpufreq powernv driver fixes and cleanups (Akshay Adiga, Shilpasri Bhat) - cpufreq qoriq driver fixes and cleanups (Jia Hongtao) - ACPI cpufreq driver cleanups (Viresh Kumar) - Assorted cpufreq driver updates (Ashwin Chaugule, Geliang Tang, Javier Martinez Canillas, Paul Gortmaker, Sudeep Holla) - Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann) - Fixes and cleanups in the OPP (Operating Performance Points) framework, mostly related to OPP sharing, and reorganization of OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla) - New "passive" governor for devfreq (for SoC subsystems that will rely on someone else for the management of their power resources) and consolidation of devfreq support for Exynos platforms, coding style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham) - PM core fixes and cleanups, mostly to make it work better with the generic power domains (genpd) framework, and updates for that framework (Ulf Hansson, Thierry Reding, Colin Ian King) - Intel Broxton support for the intel_idle driver (Len Brown) - cpuidle core optimization and fix (Daniel Lezcano, Dave Gerlach) - ARM cpuidle cleanups (Jisheng Zhang) - Intel Kabylake support for the RAPL power capping driver (Jacob Pan) - AVS (Adaptive Voltage Switching) rockchip-io driver update (Heiko Stuebner) - Updates for the cpupower tool (Arjun Sreedharan, Colin Ian King, Mattia Dongili, Thomas Renninger)" * tag 'pm-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (112 commits) intel_pstate: Clean up get_target_pstate_use_performance() intel_pstate: Use sample.core_avg_perf in get_avg_pstate() intel_pstate: Clarify average performance computation intel_pstate: Avoid unnecessary synchronize_sched() during initialization cpufreq: schedutil: Make default depend on CONFIG_SMP cpufreq: powernv: del_timer_sync when global and local pstate are equal cpufreq: powernv: Move smp_call_function_any() out of irq safe block intel_pstate: Clean up intel_pstate_get() cpufreq: schedutil: Make it depend on CONFIG_SMP cpufreq: governor: Fix handling of special cases in dbs_update() PM / OPP: Move CONFIG_OF dependent code in a separate file cpufreq: intel_pstate: Ignore _PPC processing under HWP cpufreq: arm_big_little: use generic OPP functions for {init, free}_opp_table PM / OPP: add non-OF versions of dev_pm_opp_{cpumask_, }remove_table cpufreq: tango: Use generic platdev driver PM / OPP: pass cpumask by reference cpufreq: Fix GOV_LIMITS handling for the userspace governor cpupower: fix potential memory leak PM / devfreq: style/typo fixes PM / devfreq: exynos: Add the detailed correlation for Exynos5422 bus ..

Commit d61a3ead ("[PATCH] IPMI: reserve I/O ports separately") changed the way I/O ports were reserved and includes this comment in log: Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI controller. This causes problems when trying to register the entire I/O region. Therefore we must register each I/O port separately. There is a similar problem with memio regions on an arm64 platform (AMD Seattle). Where I see: ipmi message handler version 39.2 ipmi_si AMDI0300:00: probing via device tree ipmi_si AMDI0300:00: ipmi_si: probing via ACPI ipmi_si AMDI0300:00: [mem 0xe0010000] regsize 1 spacing 4 irq 23 ipmi_si: Adding ACPI-specified kcs state machine IPMI System Interface driver. ipmi_si: Trying ACPI-specified kcs state machine at mem \ address 0xe0010000, slave address 0x0, irq 23 ipmi_si: Could not set up I/O space The problem is that the ACPI core registers disjoint regions for the platform device: e0010000-e0010000 : AMDI0300:00 e0010004-e0010004 : AMDI0300:00 and the ipmi_si driver tries to register one region e0010000-e0010004. Based on a patch from Mark Salter <msalter@redhat.com>, who also wrote all the above text. Signed-off-by: NCorey Minyard <cminyard@mvista.com> Tested-by: NMark Salter <msalter@redhat.com>
