Sergey reported a might sleep warning triggered from the hpet resume path. It's caused by the call to disable_irq() from interrupt disabled context. The problem with the low level resume code is that it is not accounted as a special system_state like we do during the boot process. Calling the same code during system boot would not trigger the warning. That's inconsistent at best. In this particular case it's trivial to replace the disable_irq() with disable_hardirq() because this particular code path is solely used from system resume and the involved hpet interrupts can never be force threaded.

Kirill reported a warning from UBSAN about undefined behavior when using protection keys. He is running on hardware that actually has support for it, which is not widely available. The warning triggers because of very large shifts of integers when doing a pkey_free() of a large, invalid value. This happens because we never check that the pkey "fits" into the mm_pkey_allocation_map(). I do not believe there is any danger here of anything bad happening other than some aliasing issues where somebody could do: pkey_free(35); and the kernel would effectively execute: pkey_free(8); While this might be confusing to an app that was doing something stupid, it has to do something stupid and the effects are limited to the app shooting itself in the foot.

The hot removal of IOAPIC is handling PCI and ACPI removal in one go. That only works when the PCI drivers released the interrupt resources, but breaks when a IOAPIC interrupt is still associated to a PCI device. The new pcibios_release_device() callback allows to solve that problem by splitting the removal into two steps: 1) PCI removal: Release all PCI resources including eventually not yet released IOAPIC interrupts via the new pcibios_release_device() callback. 2) ACPI removal: After release of all PCI resources the ACPI resources can be released without issue.

由 Rui Wang 提交于
The revert of 991de2e5 ("PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()") causes a problem for IOAPIC hotplug. The problem is that IRQs are allocated and freed in pci_enable_device() and pci_disable_device(). But there are some drivers which don't call pci_disable_device(), and they have good reasons not calling it, so if they're using IOAPIC their IRQs won't have a chance to be released from the IOAPIC. When this happens IOAPIC hot-removal fails with a kernel stack dump and an error message like this: [149335.697989] pin16 on IOAPIC2 is still in use. It turns out that we can fix it in a different way without moving IRQ allocation into pcibios_alloc_irq(), thus avoiding the regression of 991de2e5. We can keep the allocation and freeing of IRQs as is within pci_enable_device()/pci_disable_device(), without breaking any previous assumption of the rest of the system, keeping compatibility with both the legacy and the modern drivers. We can accomplish this by implementing the existing __weak hook of pcibios_release_device() thus when a pci device is about to be deleted we get notified in the hook and take the chance to release its IRQ, if any, from the IOAPIC. Implement pcibios_release_device() for x86 to release any IRQ not released by the driver.

Kernel erases R8..R11 registers prior returning to userspace from int80: https://lkml.org/lkml/2009/10/1/164 GCC can reuse these registers and doesn't expect them to change during syscall invocation. I met this kind of bug in CRIU once GCC 6.1 and CLANG stored local variables in those registers and the kernel zerofied them during syscall: https://github.com/xemul/criu/commit/990d33f1a1cdd17bca6c2eb059ab3be2564f7fa2 By that reason I suggest to add those registers to clobbers in selftests.

Merging the two codebases lets us share the memory allocation pools, and results in a net deletion of 500 lines of code.

Pull networking fixes from David Miller: 1) Don't save TIPC header values before the header has been validated, from Jon Paul Maloy. 2) Fix memory leak in RDS, from Zhu Yanjun. 3) We miss to initialize the UID in the flow key in some paths, from Julian Anastasov. 4) Fix latent TOS masking bug in the routing cache removal from years ago, also from Julian. 5) We forget to set the sockaddr port in sctp_copy_local_addr_list(), fix from Xin Long. 6) Missing module ref count drop in packet scheduler actions, from Roman Mashak. 7) Fix RCU annotations in rht_bucket_nested, from Herbert Xu. 8) Fix use after free which happens because L2TP's ipv4 support returns non-zero values from it's backlog_rcv function which ipv4 interprets as protocol values.

The link between the iommu sysfs-device and the struct amd_iommu is no longer stored as driver-data. Update the code to the new correct way of getting from device to amd_iommu.

Round the initrd memblock reservation to page boundaries to prevent other data sharing the initrd pages. This prevents an allocation possibly overlapping with the initrd, which would later get trampled on in free_initrd_mem(). Signed-off-by: NRussell King <rmk+kernel@armlinux.org.uk>

The tegra DRM driver produces a harmless warning when built for NOMMU: drivers/gpu/drm/tegra/gem.c: In function 'tegra_drm_mmap': drivers/gpu/drm/tegra/gem.c:508:12: unused variable 'prot' This is because pgprot_writecombine() on ARM returns a constant and ignores its argument. The version in asm-generic doesn't have that problem, so let's use that one instead. We don't actually care about the value on NOMMU, and this is consistent with what some other architectures do.

The decompress.c file contains a declaration for strstr() so we can include some compression library code. With the updated LZ4 implementation, we run into the same problem again for strlen(): In file included from ../include/linux/rcupdate.h:40:0, from ../include/linux/srcu.h:33, from ../include/linux/notifier.h:15, from ../include/linux/memory_hotplug.h:6, from ../include/linux/mmzone.h:749, from ../include/linux/gfp.h:5, from ../include/linux/kmod.h:22, from ../include/linux/module.h:13, from ../arch/arm/boot/compressed/../../../../lib/lz4/lz4_decompress.c:39, from ../arch/arm/boot/compressed/../../../../lib/decompress_unlz4.c:13, from ../arch/arm/boot/compressed/decompress.c:55: include/linux/cpumask.h: In function 'cpumask_parse': include/linux/cpumask.h:592:53: error: implicit declaration of function 'strlen';did you mean 'strstr'?
