[PATCH V3] ARM: dts: omap3: Fix am3517 mdio and emac clock references

by Adam Ford

A previous patch removed OMAP clock aliases that were perceived to be unnecessary. Unfortunately, it broke the ethernet on the am3517-evm. This patch enables the MDIO clock and EMAC clock.

[PATCH] vmw_balloon: fix inflation with batching

by Nadav Amit

Embarrassingly, the recent fix introduced worse problem than it solved, causing the balloon not to inflate. The VM informed the hypervisor that the pages for lock/unlock are sitting in the wrong address, as it used the page that is used the uninitialized page variable.

[PATCH] usb/host/pci-quirks: Only reset USB bus on NVIDIA devices

by Paul Menzel

Currently, on the AMD board Asus F2A85-M Pro there is a 100 ms delay as the USB bus of each of the two OHCI PCI devices is reset. As a 50 ms delay is done per the USB specification. Commit c6187597 (OHCI: final fix for NVIDIA problems (I hope)) unconditionally does the bus reset for all chipsets, while it was only doen for NVIDIA chipsets before. As it should not be needed for non-NVIDIA chipsets, only do the reset for Nvidia devices. Tested on Asus F2A85-M PRO and ASRock E350M1. The USB keyboard works and the LUKS passphrase can be e ntered.

[PATCH] IB/hfi1: Fix user context tail allocation for DMA_RTAIL

by Mike Marciniszyn

commit 1bc0299d976e000ececc6acd76e33b4582646cb7 upstream. The following code fails to allocate a buffer for the tail address that the hardware DMAs into when the user context DMA_RTAIL is set. if (HFI1_CAP_KGET_MASK(rcd->flags, DMA_RTAIL)) { rcd->rcvhdrtail_kvaddr = dma_zalloc_coherent( &dd->pcidev->dev, PAGE_SIZE, &dma_hdrqtail, gfp_flags); if (!rcd->rcvhdrtail_kvaddr) goto bail_free; rcd->rcvhdrqtailaddr_dma = dma_hdrqtail; } So the rcvhdrtail_kvaddr would then be NULL. The mmap logic fails to check for a NULL rcvhdrtail_kvaddr. The fix is to test for both user and kernel DMA_TAIL options during the allocation as well as testing for a NULL rcvhdrtail_kvaddr during the mmap processing. Additionally, all downstream testing of the capmask for DMA_RTAIL have been eliminated in favor of testing rcvhdrtail_kvaddr. The patch had to be adjusted for lack of VNIC and interating contexts differently in the 4.9 code base. Reviewed-by: Michael J.

[PATCH] sched/nohz: Skip remote tick on idle task entirely

by Frederic Weisbecker

Some people have reported that the warning in sched_tick_remote() occasionally triggers, especially in favour of some RCU-Torture pressure: WARNING: CPU: 11 PID: 906 at kernel/sched/core.c:3138 sched_tick_remote+0xb6/0xc0 Modules linked in: CPU: 11 PID: 906 Comm: kworker/u32:3 Not tainted 4.18.0-rc2+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1 04/01/2014 Workqueue: events_unbound sched_tick_remote RIP: 0010:sched_tick_remote+0xb6/0xc0 Code: e8 0f 06 b8 00 c6 03 00 fb eb 9d 8b 43 04 85 c0 75 8d 48 8b 83 e0 0a 00 00 48 85 c0 75 81 eb 88 48 89 df e8 bc fe ff ff eb aa <0f> 0b eb +c5 66 0f 1f 44 00 00 bf 17 00 00 00 e8 b6 2e fe ff 0f b6 Call Trace: process_one_work+0x1df/0x3b0 worker_thread+0x44/0x3d0 kthread+0xf3/0x130 ? set_worker_desc+0xb0/0xb0 ? kthread_create_worker_on_cpu+0x70/0x70 ret_from_fork+0x35/0x40 This happens when the remote tick applies on an idle task. Usually the idle_cpu() check avoids that, but it is performed before we lock the runqueue and it is therefore racy. It was intended to be that way in order to prevent from useless runqueue locks since idle task tick callback is a no-op. Now if the racy check slips out of our hands and we end up remotely ticking an idle task, the empty task_tick_idle() is harmless. Still it won't pass the WARN_ON_ONCE() test that ensures rq_clock_task() is not too far from curr->se.exec_start because update_curr_idle() doesn't update the exec_start value like other scheduler policies. Hence the reported false positive. So let's have another check, while the rq is locked, to make sure we don't remote tick on an idle task. The lockless idle_cpu() still applies to avoid unecessary rq lock contention. Reported-by: Jacek Tomaka <jacekt(a)dug.com> Reported-by: Paul E.
