2019-06-03sched/core: Provide a pointer to the valid CPU maskSebastian Andrzej Siewior6-9/+9
In commit: 4b53a3412d66 ("sched/core: Remove the tsk_nr_cpus_allowed() wrapper") the tsk_nr_cpus_allowed() wrapper was removed. There was not much difference in !RT but in RT we used this to implement migrate_disable(). Within a migrate_disable() section the CPU mask is restricted to single CPU while the "normal" CPU mask remains untouched. As an alternative implementation Ingo suggested to use: struct task_struct { const cpumask_t *cpus_ptr; cpumask_t cpus_mask; }; with t->cpus_ptr = &t->cpus_mask; In -RT we then can switch the cpus_ptr to: t->cpus_ptr = &cpumask_of(task_cpu(p)); in a migration disabled region. The rules are simple: - Code that 'uses' ->cpus_allowed would use the pointer. - Code that 'modifies' ->cpus_allowed would use the direct mask.

2019-06-02sparc: perf: fix updated event period in response to PERF_EVENT_IOC_PERIODYoung Xiao1-0/+4
The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the sample period of a running perf_event. Consequently, when calculating the next event period, the new period will only be considered after the previous one has overflowed. This patch changes the calculation of the remaining event ticks so that they are offset if the period has changed.

2019-06-02powerpc/pseries: Fix xive=off command lineGreg Kurz2-2/+66
On POWER9, if the hypervisor supports XIVE exploitation mode, the guest OS will unconditionally requests for the XIVE interrupt mode even if XIVE was deactivated with the kernel command line xive=off. Later on, when the spapr XIVE init code handles xive=off, it disables XIVE and tries to fall back on the legacy mode XICS. This discrepency causes a kernel panic because the hypervisor is configured to provide the XIVE interrupt mode to the guest : kernel BUG at arch/powerpc/sysdev/xics/xics-common.c:135! ... NIP xics_smp_probe+0x38/0x98 LR xics_smp_probe+0x2c/0x98 Call Trace: xics_smp_probe+0x2c/0x98 (unreliable) pSeries_smp_probe+0x40/0xa0 smp_prepare_cpus+0x62c/0x6ec kernel_init_freeable+0x148/0x448 kernel_init+0x2c/0x148 ret_from_kernel_thread+0x5c/0x68 Look for xive=off during prom_init and don't ask for XIVE in this case. One exception though: if the host only supports XIVE, we still want to boot so we ignore xive=off. Similarly, have the spapr XIVE init code to looking at the interrupt mode negotiated during CAS, and ignore xive=off if the hypervisor only supports XIVE.

2019-06-02powerpc/powernv/npu: Fix reference leakGreg Kurz1-1/+14
Since 902bdc57451c, get_pci_dev() calls pci_get_domain_bus_and_slot(). This has the effect of incrementing the reference count of the PCI device, as explained in drivers/pci/search.c: * Given a PCI domain, bus, and slot/function number, the desired PCI * device is located in the list of PCI devices. If the device is * found, its reference count is increased and this function returns a * pointer to its data structure. The caller must decrement the * reference count by calling pci_dev_put(). If no device is found, * %NULL is returned. Nothing was done to call pci_dev_put() and the reference count of GPU and NPU PCI devices rockets up. A natural way to fix this would be to teach the callers about the change, so that they call pci_dev_put() when done with the pointer. This turns out to be quite intrusive, as it affects many paths in npu-dma.c, pci-ioda.c and vfio_pci_nvlink2.c. Also, the issue appeared in 4.16 and some affected code got moved around since then: it would be problematic to backport the fix to stable releases. All that code never cared for reference counting anyway. Call pci_dev_put() from get_pci_dev() to revert to the previous behavior.

2019-06-01treewide: fix typos of SPDX-License-IdentifierMasahiro Yamada1-1/+1
Prior to the adoption of SPDX, it was difficult for tools to determine the correct license due to incomplete or badly formatted license text. The SPDX solves this issue, assuming people can correctly spell "SPDX-License-Identifier" although this assumption is broken in some places. Since scripts/spdxcheck.py parses only lines that exactly matches to the correct tag, it cannot (should not) detect this kind of error. If the correct tag is missing, scripts/checkpatch.pl warns like this: WARNING: Missing or malformed SPDX-License-Identifier tag in line * So, people should notice it before the patch submission, but in reality broken tags sometimes slip in. The checkpatch warning is not useful for checking the committed files globally since large number of files still have no SPDX tag. Also, I am not sure about the legal effect when the SPDX tag is broken. Anyway, these typos are absolutely worth fixing.

Lots of exciting new features in the first PR of this developement cycle! The main changes are: 1) misc verifier improvements, from Alexei. 2) bpftool can now convert btf to valid C, from Andrii. 3) verifier can insert explicit ZEXT insn when requested by 32-bit JITs. This feature greatly improves BPF speed on 32-bit architectures. From Jiong. 4) cgroups will now auto-detach bpf programs. This fixes issue of thousands bpf programs got stuck in dying cgroups. From Roman. 5) new bpf_send_signal() helper, from Yonghong. 6) cgroup inet skb programs can signal CN to the stack, from Lawrence. 7) miscellaneous cleanups, from many developers. ==================== Signed-off-by: David S.

2019-05-31bpf, riscv: clear high 32 bits for ALU32 add/sub/neg/lsh/rsh/arshLuke Nelson1-0/+18
In BPF, 32-bit ALU operations should zero-extend their results into the 64-bit registers. The current BPF JIT on RISC-V emits incorrect instructions that perform sign extension only (e.g., addw, subw) on 32-bit add, sub, lsh, rsh, arsh, and neg. This behavior diverges from the interpreter and JITs for other architectures. This patch fixes the bugs by performing zero extension on the destination register of 32-bit ALU operations.

2019-05-31ARM: mach-shmobile: Don't init CNTVOFF/counter if PSCI is availableOleksandr Tyshchenko1-0/+17
If PSCI is available then most likely we are running on PSCI-enabled U-Boot which, we assume, has already taken care of resetting CNTVOFF and updating counter module before switching to non-secure mode and we don't need to. As the psci_smp_available() helper always returns false if CONFIG_SMP is disabled, it can't be used safely as an indicator of PSCI usage. For that reason, we check for the mandatory PSCI operation to be available. Please note, an extra check to prevent secure_cntvoff_init() from being called for secondary CPUs in headsmp-apmu.S is not needed, as SMP code for APMU based system is not executed if PSCI is in use.

2019-05-31nds32: Avoid IEX status being incorrectly modifiedVincent Chen9-46/+58
In order for kernel to capture each denormalized output, the UDF trapping enable bit is always raised in $fpcsr. Because underflow case will issue not an underflow exception but also an inexact exception, it causes that the IEX, IEX cumulative exception, flag in $fpcsr to be raised in each denormalized output handling. To make the emulation transparent to the user, the emulator needs to clear the IEX flag in $fpcsr if the result is a denormalized number. However, if the IEX flag has been raised before this floating point emulation, this cleanup may be incorrect. To avoid the IEX flags in $fpcsr be raised in each denormalized output handling, the IEX trap shall be always enabled.
