[PATCH] PCI/portdrv: do not disable device on remove()

by Sinan Kaya

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. pci_disable_device() has a much wider impact then port service itself and it prevents all inbound transactions to reach to the system and impacts the entire PCI traffic behind the bridge. Issue is that pcie_port_device_remove() doesn't maintain any coordination with the rest of the PCI device drivers in the system before clearing the bus master bit. This has been found to cause crashes on HP DL360 Gen9 machines during reboot. Besides, kexec is already clearing the bus master bit in pci_device_shutdown() after all PCI drivers are removed. Just remove the extra clear here.

[PATCH for-next 0/5] IB/hfi1,isert: Updates for-next 5/15/2018

by Dennis Dalessandro

Hi Doug and Jason, Here are some patches to go to for-next. One is a code cleanup. The rest are bug fixes that are probably not serious enough for an -rc6. The one that may be on the fence is the isert patch. Since it only affects debug kernels it can probably even wait till for-next. It has been marked stable though. --- Alex Estrin (1): IB/isert: Fix for lib/dma_debug check_sync warning Kamenee Arumugam (1): IB/Hfi1: Mask Unsupported Request error bit in PCIe AER Michael J.

+ kasan-fix-memory-hotplug-during-boot.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: kasan: fix memory hotplug during boot has been added to the -mm tree. Its filename is kasan-fix-memory-hotplug-during-boot.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/kasan-fix-memory-hotplug-during-bo… and later at http://ozlabs.org/~akpm/mmotm/broken-out/kasan-fix-memory-hotplug-during-bo… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: kasan: fix memory hotplug during boot Using module_init() is wrong. E.g. ACPI adds and onlines memory before our memory notifier gets registered. This makes sure that ACPI memory detected during boot up will not result in a kernel crash. Easily reproducible with QEMU, just specify a DIMM when starting up.

[PATCH for-next] IB/qib: Fix DMA api warning with debug kernel

Fix by testing for pci_dma_mapping_error() in all cases and properly handling the failure in the caller. Additionally, streamline qib_map_page() arguments to satisfy just the single caller.
