Pull irq fixes from Thomas Gleixner: "This udpate delivers: - A fix for dynamic interrupt allocation on x86 which is required to exclude the GSI interrupts from the dynamic allocatable range.

As trace event triggers are now part of the mainline kernel, I added my trace event trigger tests to my test suite I run on all my kernels. Now these tests get run under different config options, and one of those options is CONFIG_PROVE_RCU, which checks under lockdep that the rcu locking primitives are being used correctly. This triggered the following splat: =============================== [ INFO: suspicious RCU usage. ] 3.15.0-rc2-test+ #11 Not tainted ------------------------------- kernel/trace/trace_events_trigger.c:80 suspicious rcu_dereference_check() usage! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 0 4 locks held by swapper/1/0: #0: ((&(&j_cdbs->work)->timer)){..-...}, at: [<ffffffff8104d2cc>] call_timer_fn+0x5/0x1be #1: (&(&pool->lock)->rlock){-.-...}, at: [<ffffffff81059856>] __queue_work+0x140/0x283 #2: (&p->pi_lock){-.-.-.}, at: [<ffffffff8106e961>] try_to_wake_up+0x2e/0x1e8 #3: (&rq->lock){-.-.-.}, at: [<ffffffff8106ead3>] try_to_wake_up+0x1a0/0x1e8 stack backtrace: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 3.15.0-rc2-test+ #11 Hardware name: /DG965MQ, BIOS MQ96510J.86A.0372.2006.0605.1717 06/05/2006 0000000000000001 ffff88007e083b98 ffffffff819f53a5 0000000000000006 ffff88007b0942c0 ffff88007e083bc8 ffffffff81081307 ffff88007ad96d20 0000000000000000 ffff88007af2d840 ffff88007b2e701c ffff88007e083c18 Call Trace: <IRQ> [<ffffffff819f53a5>] dump_stack+0x4f/0x7c [<ffffffff81081307>] lockdep_rcu_suspicious+0x107/0x110 [<ffffffff810ee51c>] event_triggers_call+0x99/0x108 [<ffffffff810e8174>] ftrace_event_buffer_commit+0x42/0xa4 [<ffffffff8106aadc>] ftrace_raw_event_sched_wakeup_template+0x71/0x7c [<ffffffff8106bcbf>] ttwu_do_wakeup+0x7f/0xff [<ffffffff8106bd9b>] ttwu_do_activate.constprop.126+0x5c/0x61 [<ffffffff8106eadf>] try_to_wake_up+0x1ac/0x1e8 [<ffffffff8106eb77>] wake_up_process+0x36/0x3b [<ffffffff810575cc>] wake_up_worker+0x24/0x26 [<ffffffff810578bc>] insert_work+0x5c/0x65 [<ffffffff81059982>] __queue_work+0x26c/0x283 [<ffffffff81059999>] ? __queue_work+0x283/0x283 [<ffffffff810599b7>] delayed_work_timer_fn+0x1e/0x20 [<ffffffff8104d3a6>] call_timer_fn+0xdf/0x1be^M [<ffffffff8104d2cc>] ? call_timer_fn+0x5/0x1be [<ffffffff81059999>] ? __queue_work+0x283/0x283 [<ffffffff8104d823>] run_timer_softirq+0x1a4/0x22f^M [<ffffffff8104696d>] __do_softirq+0x17b/0x31b^M [<ffffffff81046d03>] irq_exit+0x42/0x97 [<ffffffff81a08db6>] smp_apic_timer_interrupt+0x37/0x44 [<ffffffff81a07a2f>] apic_timer_interrupt+0x6f/0x80 <EOI> [<ffffffff8100a5d8>] ? default_idle+0x21/0x32 [<ffffffff8100a5d6>] ? default_idle+0x1f/0x32 [<ffffffff8100ac10>] arch_cpu_idle+0xf/0x11 [<ffffffff8107b3a4>] cpu_startup_entry+0x1a3/0x213 [<ffffffff8102a23c>] start_secondary+0x212/0x219 The cause is that the triggers are protected by rcu_read_lock_sched() but the data is dereferenced with rcu_dereference() which expects it to be protected with rcu_read_lock().

Pull ACPI and power management fixes from Rafael Wysocki: "A bunch of regression fixes this time. They fix two regressions in the PNP subsystem, one in the ACPI processor driver and one in the ACPI EC driver, four cpufreq driver regressions and an unrelated bug in one of the drivers. The regressions are recent or introduced in 3.14. Specifics: - There are two bugs in the ACPI PNP core that cause errors to be returned if optional ACPI methods are not present. After an ACPI core change made in 3.14 one of those errors leads to serial port suspend failures on some systems. Fix from Rafael J Wysocki. - A recently added PNP quirk related to Intel chipsets intorduced a build error in unusual configurations (PNP without PCI). Fix from Bjorn Helgaas. - An ACPI EC workaround related to system suspend on Samsung machines added in 3.14 introduced a race causing some valid EC events to be discarded. Fix from Kieran Clancy. - The acpi-cpufreq driver fails to load on some systems after a 3.14 commit related to APIC ID parsing that overlooked one corner case. Fix from Lan Tianyu. - Fix for a recently introduced build problem in the ppc-corenet cpufreq driver from Tim Gardner. - A recent cpufreq core change to ensure serialization of frequency transitions for drivers with a ->target_index() callback overlooked the fact that some of those drivers had been doing operations introduced by it into the core already by themselves. That resulted in a mess in which the core and the drivers try to do the same thing and block each other which leads to deadlocks.

There are only a couple of architectures that override _STK_LIM_MAX to a non-infinity value. This changes the stack allocation semantics in subtle ways. For example, GNU make changes its stack allocation to the hard maximum defined by _STK_LIM_MAX. As a results, threads executed by processes running under make are allocated a stack size of _STK_LIM_MAX rather than a sensible default value. This causes various thread stress tests to fail when they can't muster more than about 50 threads. The attached change implements the default behavior used by the majority of architectures.

This reverts commit 9fb6c9c7. Tjmax on some Intel CPUs is below 85 degrees C. One known example is L5630 with Tjmax of 71 degrees C. There are other Xeon processors with Tjmax of 70 or 80 degrees C. Also, the Intel IA32 System Programming document states that the temperature target is in bits 23:16 of MSR 0x1a2 (MSR_TEMPERATURE_TARGET), which is 8 bits, not 7. So even if turbostat uses similar checks to validate Tjmax, there is no evidence that the checks are actually required. On the contrary, the checks are known to cause problems and therefore need to be removed. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=75071.

According commit d640113f (ACPI: processor: fix acpi_get_cpuid for UP processor), BIOS may not provide _MAT or MADT tables and acpi_get_apicid() always returns -1. For these cases, original code will pass apic_id with vaule of -1 to acpi_map_cpuid() and it will check the acpi_id. If acpi_id is equal to zero, ignores apic_id and return zero for CPU0. Commit b981513f (ACPI / scan: bail out early if failed to parse APIC ID for CPU) changed the behavior. Return ENODEV when find apic_id is less than zero after calling acpi_get_apicid(). This causes acpi-cpufreq driver fails to be loaded on some machines. This patch is to fix it.

The ACPI PNP subsystem returns errors from pnpacpi_set_resources() and pnpacpi_disable_resources() if the _SRS or _DIS methods are not present, respectively, but it should not do that, because those methods are optional. For this reason, modify pnpacpi_set_resources() and pnpacpi_disable_resources(), respectively, to ignore missing _SRS or _DIS. This problem has been uncovered by commit 202317a5 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace) and manifested itself by causing serial port suspend to fail on some systems.

arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.

The array debugfs_known_mountpoints[] will cause extra '/' character output. Remove it. pre: $ perf probe -l /sys/kernel/debug//tracing/uprobe_events file does not exist - please rebuild kernel with CONFIG_UPROBE_EVENTS. post: $ perf probe -l /sys/kernel/debug/tracing/uprobe_events file does not exist - please rebuild kernel with CONFIG_UPROBE_EVENTS.

Modules installed outside of the kernel's build system should go into "%s/lib/modules/%s/extra", but at present, perf will only look at them when they are in "%s/lib/modules/%s/kernel". Lets encourage good citizenship by relaxing this requirement to "%s/lib/modules/%s". This way open source modules that are out-of-tree have no incentive to start populating a directory reserved for in-kernel modules and I can stop hex-editing my system's perf binary when profiling OSS out-of-tree modules. Feedback from Namhyung Kim correctly revealed that the hex-edits that I had been doing meant that perf was also traversing the build and source symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly exclude them from traversal with a minor tweak to the traversal routine.

There's false assumption in the library detection code assuming -liberty and -lz are always present once bfd is detected. The fails on Ubuntu (14.04) as reported by Ingo.
