2016-09-23MIPS: Fix pre-r6 emulation FPU initialisationPaul Burton1-0/+2
In the mipsr2_decoder() function, used to emulate pre-MIPSr6 instructions that were removed in MIPSr6, the init_fpu() function is called if a removed pre-MIPSr6 floating point instruction is the first floating point instruction used by the task. However, init_fpu() performs varous actions that rely upon not being migrated. For example in the most basic case it sets the coprocessor 0 Status.CU1 bit to enable the FPU & then loads FP register context into the FPU registers. If the task were to migrate during this time, it may end up attempting to load FP register context on a different CPU where it hasn't set the CU1 bit, leading to errors such as: do_cpu invoked from kernel context![#2]: CPU: 2 PID: 7338 Comm: fp-prctl Tainted: G D 4.7.0-00424-g49b0c82 #2 task: 838e4000 ti: 88d38000 task.ti: 88d38000 $ 0 : 00000000 00000001 ffffffff 88d3fef8 $ 4 : 838e4000 88d38004 00000000 00000001 $ 8 : 3400fc01 801f8020 808e9100 24000000 $12 : dbffffff 807b69d8 807b0000 00000000 $16 : 00000000 80786150 00400fc4 809c0398 $20 : 809c0338 0040273c 88d3ff28 808e9d30 $24 : 808e9d30 00400fb4 $28 : 88d38000 88d3fe88 00000000 8011a2ac Hi : 0040273c Lo : 88d3ff28 epc : 80114178 _restore_fp+0x10/0xa0 ra : 8011a2ac mipsr2_decoder+0xd5c/0x1660 Status: 1400fc03 KERNEL EXL IE Cause : 1080002c (ExcCode 0b) PrId : 0001a920 (MIPS I6400) Modules linked in: Process fp-prctl (pid: 7338, threadinfo=88d38000, task=838e4000, tls=766527d0) Stack : 00000000 00000000 00000000 88d3fe98 00000000 00000000 809c0398 809c0338 808e9100 00000000 88d3ff28 00400fc4 00400fc4 0040273c 7fb69e18 004a0000 004a0000 004a0000 7664add0 8010de18 00000000 00000000 88d3fef8 88d3ff28 808e9100 00000000 766527d0 8010e534 000c0000 85755000 8181d580 00000000 00000000 00000000 004a0000 00000000 766527d0 7fb69e18 004a0000 80105c20 ...

2016-09-23arm64: Call numa_store_cpu_info() earlier.David Daney1-8/+6
The wq_numa_init() function makes a private CPU to node map by calling cpu_to_node() early in the boot process, before the non-boot CPUs are brought online. Since the default implementation of cpu_to_node() returns zero for CPUs that have never been brought online, the workqueue system's view is that *all* CPUs are on node zero. When the unbound workqueue for a non-zero node is created, the tsk_cpus_allowed() for the worker threads is the empty set because there are, in the view of the workqueue system, no CPUs on non-zero nodes. The code in try_to_wake_up() using this empty cpumask ends up using the cpumask empty set value of NR_CPUS as an index into the per-CPU area pointer array, and gets garbage as it is one past the end of the array. This results in: [ 0.881970] Unable to handle kernel paging request at virtual address fffffb1008b926a4 [ 1.970095] pgd = fffffc00094b0000 [ 1.973530] [fffffb1008b926a4] *pgd=0000000000000000, *pud=0000000000000000, *pmd=0000000000000000 [ 1.982610] Internal error: Oops: 96000004 [#1] SMP [ 1.987541] Modules linked in: [ 1.990631] CPU: 48 PID: 295 Comm: cpuhp/48 Tainted: G W 4.8.0-rc6-preempt-vol+ #9 [ 1.999435] Hardware name: Cavium ThunderX CN88XX board (DT) [ 2.005159] task: fffffe0fe89cc300 task.stack: fffffe0fe8b8c000 [ 2.011158] PC is at try_to_wake_up+0x194/0x34c [ 2.015737] LR is at try_to_wake_up+0x150/0x34c [ 2.020318] pc : [<fffffc00080e7468>] lr : [<fffffc00080e7424>] pstate: 600000c5 [ 2.027803] sp : fffffe0fe8b8fb10 [ 2.031149] x29: fffffe0fe8b8fb10 x28: 0000000000000000 [ 2.036522] x27: fffffc0008c63bc8 x26: 0000000000001000 [ 2.041896] x25: fffffc0008c63c80 x24: fffffc0008bfb200 [ 2.047270] x23: 00000000000000c0 x22: 0000000000000004 [ 2.052642] x21: fffffe0fe89d25bc x20: 0000000000001000 [ 2.058014] x19: fffffe0fe89d1d00 x18: 0000000000000000 [ 2.063386] x17: 0000000000000000 x16: 0000000000000000 [ 2.068760] x15: 0000000000000018 x14: 0000000000000000 [ 2.074133] x13: 0000000000000000 x12: 0000000000000000 [ 2.079505] x11: 0000000000000000 x10: 0000000000000000 [ 2.084879] x9 : 0000000000000000 x8 : 0000000000000000 [ 2.090251] x7 : 0000000000000040 x6 : 0000000000000000 [ 2.095621] x5 : ffffffffffffffff x4 : 0000000000000000 [ 2.100991] x3 : 0000000000000000 x2 : 0000000000000000 [ 2.106364] x1 : fffffc0008be4c24 x0 : ffffff0ffffada80 [ 2.111737] [ 2.113236] Process cpuhp/48 (pid: 295, stack limit = 0xfffffe0fe8b8c020) [ 2.120102] Stack: (0xfffffe0fe8b8fb10 to 0xfffffe0fe8b90000) [ 2.125914] fb00: fffffe0fe8b8fb80 fffffc00080e7648 . . .

2016-09-22perf/core: Limit matching exclusive events to one PMUAlexander Shishkin1-1/+1
An "exclusive" PMU is the one that can only have one event scheduled in at any given time. There may be more than one of such PMUs in a system, though, like Intel PT and BTS. It should be allowed to have one event for either of those inside the same context (there may be other constraints that may prevent this, but those would be hardware-specific). However, the exclusivity code is written so that only one event from any of the "exclusive" PMUs is allowed in a context. Fix this by making the exclusive event filter explicitly match two events' PMUs.

2016-09-22perf/x86/intel/bts: Make it an exclusive PMUAlexander Shishkin1-1/+2
Just like intel_pt, intel_bts can only handle one event at a time, which is the reason we introduced PERF_PMU_CAP_EXCLUSIVE in the first place. However, at the moment one can have as many intel_bts events within the same context at the same time as one pleases. Only one of them, however, will get scheduled and receive the actual trace data. Fix this by making intel_bts an "exclusive" PMU.

So for this case a fence_array is not created instead we just assigned the fence to sync_file->fence. Then we do not use the fences array anymore nor does free it. This patch frees the array.

2016-09-22drm/i2c: tda998x: don't register the connectorBrian Starkey1-8/+0
The connector shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As drm_dev_register() now registers all of the connectors anyway, there's no need to explicitly do it in individual drivers so remove the calls to drm_connector_register()/drm_connector_unregister(). This allows componentised drivers to use tda998x without having racy initialisation.
