git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull SMP hotplug update from Thomas Gleixner: "This contains a trivial typo fix and an extension to the core code for dynamically allocating states in the prepare stage. The extension is necessary right now because we need a proper way to unbreak LTTNG, which iscurrently non functional due to the removal of the notifiers. Surely it's out of tree, but it's widely used by distros. The simple solution would have been to reserve a state for LTTNG, but I'm not fond about unused crap in the kernel and the dynamic range, which we admittedly should have done right away, allows us to remove quite some of the hardcoded states, i.e. those which have no ordering requirements.

commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC chip and did not add it to the new IO-APIC-IR irq chip. Unfortunately the software resend fallback is not enabled on X86, so edge interrupts which are received during the lazy disabled state of the interrupt line are not retriggered and therefor lost.

When the plane is invisible we may have all sorts of bogus stuff in the coordinates, which we must ignore or else we might fail the plane update. This started to happen on SKL when I moved the plane offset computation to happen in the check phase.

2017-01-18drm/i915: Remove WaDisableLSQCROPERFforOCL KBL workaround.Francisco Jerez2-18/+0
The WaDisableLSQCROPERFforOCL workaround has the side effect of disabling an L3SQ optimization that has huge performance implications and is unlikely to be necessary for the correct functioning of usual graphic workloads. Userspace is free to re-enable the workaround on demand, and is generally in a better position to determine whether the workaround is necessary than the DRM is (e.g. only during the execution of compute kernels that rely on both L3 fences and HDC R/W requests). The same workaround seems to apply to BDW (at least to production stepping G1) and SKL as well (the internal workaround database claims that it does for all steppings, while the BSpec workaround table only mentions pre-production steppings), but the DRM doesn't do anything beyond whitelisting the L3SQCREG4 register so userspace can enable it when it sees fit. Do the same on KBL platforms. Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%, and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master -- This is followed by a regression of 35% and 10% respectively for the same benchmarks and platform caused by my recent patch series switching userspace to use the dataport constant cache instead of the sampler to implement uniform pull constant loads, which caused us to hit more heavily the L3 cache (and on platforms other than KBL had the opposite effect of improving performance of the same two benchmarks). The overall effect on KBL of this change combined with the recent userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf was affected by the constant cache changes (though it improved as it did on other platforms rather than regressing), but is not significantly affected by this patch (with statistical significance of 5% and sample size 20). v2: Drop some more code to avoid unused variable warning.

2017-01-18ovl: fix possible use after free on redirect dir lookupAmir Goldstein1-9/+18
ovl_lookup_layer() iterates on path elements of d->name.name but also frees and allocates a new pointer for d->name.name. For the case of lookup in upper layer, the initial d->name.name pointer is stable (dentry->d_name), but for lower layers, the initial d->name.name can be d->redirect, which can be freed during iteration. [SzM] Keep the count of remaining characters in the redirect path and calculate the current position from that. This works becuase only the prefix is modified, the ending always stays the same.

Setting it in c_can_pci_probe() like c_can_plat_probe() prevents c_can_pci.ko from crashing, with and without CONFIG_PM. This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.

2017-01-17bpf: Fix test_lru_sanity5() in test_lru_map.cMartin KaFai Lau1-26/+27
test_lru_sanity5() fails when the number of online cpus is fewer than the number of possible cpus. It can be reproduced with qemu by using cmd args "--smp cpus=2,maxcpus=8". The problem is the loop in test_lru_sanity5() is testing 'i' which is incorrect. This patch: 1. Make sched_next_online() always return -1 if it cannot find a next cpu to schedule the process. 2. In test_lru_sanity5(), the parent process does sched_setaffinity() first (through sched_next_online()) and the forked process will inherit it according to the 'man sched_setaffinity'.

2017-01-17ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFSNeil Armstrong2-1/+5
The current hardware is not able to run with all cores enabled at a cluster frequency superior at 1536MHz. But the currently shipped u-boot for the platform still reports an OPP table with possible DVFS frequency up to 2GHz, and will not change since the off-tree linux tree supports limiting the OPPs with a kernel parameter. A recent u-boot change reports the boot-time DVFS around 100MHz and the default performance cpufreq governor sets the maximum frequency. Previous version of u-boot reported to be already at the max OPP and left the OPP as is. Nevertheless, other governors like ondemand could setup the max frequency and make the system crash. This patch disables the DVFS clock and disables cpufreq.

2017-01-17xfs: don't wrap ID in xfs_dq_get_next_idEric Sandeen1-0/+4
The GETNEXTQOTA ioctl takes whatever ID is sent in, and looks for the next active quota for an user equal or higher to that ID. But if we are at the maximum ID and then ask for the "next" one, we may wrap back to zero. In this case, userspace may loop forever, because it will start querying again at zero. We'll fix this in userspace as well, but for the kernel, return -ENOENT if we ask for the next quota ID past UINT_MAX so the caller knows to stop.
