kernel: Provide READ_ONCE and ASSIGN_ONCE
As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses. Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This merge does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types. This is targetted for the next merge window as Linux next already contains new offenders regarding ACCESS_ONCE vs. non-scalar types. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iQIcBAABAgAGBQJUkrVGAAoJEBF7vIC1phx8stkP/2LmN5y6LOseoEW06xa5MX4m cbIKsZNtsGHl7EDcTzzuWs6Sq5/Cj7V3yzeBF7QGbUKOqvFWU3jvpUBCCfjMg37C 77/Vf0ZPrxTXXxeJ4Ykdy2CGvuMtuYY9TWkrRNKmLU0xex7lGblEzCt9z6+mZviw 26/DN8ctjkHRvIUAi+7RfQBBc3oSMYAC1mzxYKBAsAFLV+LyFmsGU/4iofZMAsdt XFyVXlrLn0Bjx/MeceGkOlMDiVx4FnfccfFaD4hhuTLBJXWitkUK/MRa4JBiXWzH agY8942A8/j9wkI2DFp/pqZYqA/sTXLndyOWlhE//ZSti0n0BSJaOx3S27rTLkAc 5VmZEVyIrS3hyOpyyAi0sSoPkDnjeCHmQg9Rqn34/poKLd7JDrW2UkERNCf/T3eh GI2rbhAlZz3v5mIShn8RrxzslWYmOObpMr3HYNUdRk8YUfTf6d6aZ3txHp2nP4mD VBAEzsvP9rcVT2caVhU2dnBzeaZAj3zeDxBtjcb3X2osY9tI7qgLc9Fa/fWKgILk 2evkLcctsae2mlLNGHyaK3Dm/ZmYJv+57MyaQQEZNfZZgeB1y4k0DkxH4w1CFmCi s8XlH5voEHgnyjSQXXgc/PNVlkPAKr78ZyTiAfiKmh8rpe41/W4hGcgao7L9Lgiu SI0uSwKibuZt4dHGxQuG =IQ5o -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/borntraeger/linux Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger: "kernel: Provide READ_ONCE and ASSIGN_ONCE As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses.

Pull x86 apic updates from Thomas Gleixner: "After stopping the full x86/apic branch, I took some time to go through the first block of patches again, which are mostly cleanups and preparatory work for the irqdomain conversion and ioapic hotplug support. Unfortunaly one of the real problematic commits was right at the beginning, so I rebased this portion of the pending patches without the offenders. It would be great to get this into 3.19. That makes reworking the problematic parts simpler. The usual tip testing did not unearth any issues and it is fully bisectible now. I'm pretty confident that this wont affect the calmness of the xmas season. Changes: - Split the convoluted io_apic.c code into domain specific parts (vector, ioapic, msi, htirq) - Introduce proper helper functions to retrieve irq specific data instead of open coded dereferencing of pointers - Preparatory work for ioapic hotplug and irqdomain conversion - Removal of the non functional pci-ioapic driver - Removal of unused irq entry stubs - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC allocations for everything which is called from there. - Small cleanups and fixes" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ iommu/vt-d: Use helpers to access irq_cfg data structure associated with IRQ x86: irq_remapping: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Make MSI and HT_IRQ indepenent of X86_IO_APIC x86, irq: Move IRQ initialization routines from io_apic.c into vector.c x86, irq: Move IOAPIC related declarations from hw_irq.h into io_apic.h x86, irq: Move HT IRQ related code from io_apic.c into htirq.c x86, irq: Move PCI MSI related code from io_apic.c into msi.c x86, irq: Replace printk(KERN_LVL) with pr_lvl() utilities x86, irq: Make UP version of irq_complete_move() an inline stub x86, irq: Move local APIC related code from io_apic.c into vector.c x86, irq: Introduce helpers to access struct irq_cfg x86, irq: Protect __clear_irq_vector() with vector_lock x86, irq: Rename local APIC related functions in io_apic.c as apic_xxx() x86, irq: Refine hw_irq.h to prepare for irqdomain support x86, irq: Convert irq_2_pin list to generic list x86, irq: Kill useless parameter 'irq_attr' of IO_APIC_get_PCI_irq_vector() x86, irq, acpi: Get rid of special handling of GSI for ACPI SCI x86, irq: Introduce helper to check whether an IOAPIC has been registered ... |

The exciting thing here is the getting rid of stop_machine on module
removal. This is possible by using a simple atomic_t for the counter, rather than our fancy per-cpu counter: it turns out that no one is doing a module increment per net packet, so the slowdown should be in the noise.

vhost/virtio: virtio 1.0 related fixes
Most importantly, this fixes using virtio_pci as a module. Further, the big virtio 1.0 conversion missed a couple of places. This fixes them up. This isn't 100% sparse-clean yet because on many architectures get_user triggers sparse warnings when used with __bitwise tag (when same tag is on both pointer and value read).

More ACPI and power management updates for 3.19-rc1
- Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").

mm: cma: split cma-reserved in dmesg log
When the system boots up, in the dmesg logs we can see the memory statistics along with total reserved as below. Memory: 458840k/458840k available, 65448k reserved, 0K highmem When CMA is enabled, still the total reserved memory remains the same. However, the CMA memory is not considered as reserved. But, when we see /proc/meminfo, the CMA memory is part of free memory. This creates confusion. This patch corrects the problem by properly subtracting the CMA reserved memory from the total reserved memory in dmesg logs. Below is the dmesg snapshot from an arm based device with 512MB RAM and 12MB single CMA region. Before this change: Memory: 458840k/458840k available, 65448k reserved, 0K highmem After this change: Memory: 458840k/458840k available, 53160k reserved, 12288k cma-reserved, 0K highmem Signed-off-by: Pintu Kumar <pintu.k@samsung.com> Signed-off-by: Vishnu Pratap Singh <vishnu.ps@samsung.com> Acked-by: Michal Nazarewicz <mina86@mina86.com> Cc: Rafael Aquini <aquini@redhat.com> Cc: Jerome Marchand <jmarchan@redhat.com> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

3.19 changes for KVM:

XSAVES hosts were broken because the (non-KVM) XSAVES patches inadvertently changed the KVM userspace ABI whenever XSAVES was enabled; hence, this part is going to stable.

kernel: Provide READ_ONCE and ASSIGN_ONCE
ACCESS_ONCE does not work reliably on non-scalar types.

Pull user namespace related fixes from Eric Biederman: "As these are bug fixes almost all of thes changes are marked for backporting to stable. The first change (implicitly adding MNT_NODEV on remount) addresses a regression that was created when security issues with unprivileged remount were closed. I go on to update the remount test to make it easy to detect if this issue reoccurs. Then there are a handful of mount and umount related fixes. Then half of the changes deal with the a recently discovered design bug in the permission checks of gid_map. Unix since the beginning has allowed setting group permissions on files to less than the user and other permissions (aka ---rwx---rwx). As the unix permission checks stop as soon as a group matches, and setgroups allows setting groups that can not later be dropped, results in a situtation where it is possible to legitimately use a group to assign fewer privileges to a process. Which means dropping a group can increase a processes privileges. The fix I have adopted is that gid_map is now no longer writable without privilege unless the new file /proc/self/setgroups has been set to permanently disable setgroups. The bulk of user namespace using applications even the applications using applications using user namespaces without privilege remain unaffected by this change. Unfortunately this ix breaks a couple user space applications, that were relying on the problematic behavior (one of which was tools/selftests/mount/unprivileged-remount-test.c). To hopefully prevent needing a regression fix on top of my security fix I rounded folks who work with the container implementations mostly like to be affected and encouraged them to test the changes. > So far nothing broke on my libvirt-lxc test bed. :-) > Tested with openSUSE 13.2 and libvirt 1.2.9. > Tested-by: Richard Weinberger <richard@nod.at> > Tested on Fedora20 with libvirt 1.2.11, works fine. > Tested-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> > Ok, thanks - yes, unprivileged lxc is working fine with your kernels. > Just to be sure I was testing the right thing I also tested using > my unprivileged nsexec testcases, and they failed on setgroup/setgid > as now expected, and succeeded there without your patches. > Tested-by: Serge Hallyn <serge.hallyn@ubuntu.com> > I tested this with Sandstorm.

ceph: fix file lock interruption
When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng <zyan@redhat.com> |

ARM: SoC/iommu configuration for 3.19
The iomm-config branch contains work from Will Deacon, quoting his description: This series adds automatic IOMMU and DMA-mapping configuration for OF-based DMA masters described using the generic IOMMU devicetree bindings. Although there is plenty of future work around splitting up iommu_ops, adding default IOMMU domains and sorting out automatic IOMMU group creation for the platform_bus, this is already useful enough for people to port over their IOMMU drivers and start using the new probing infrastructure (indeed, Marek has patches queued for the Exynos IOMMU). The branch touches core ARM and IOMMU driver files, and the respective maintainers (Russell King and Joerg Roedel) agreed to have the contents merged through the arm-soc tree. The final version was ready just before the merge window, so we ended up delaying it a bit longer than the rest, but we don't expect to see regressions because this is just additional infrastructure that will get used in drivers starting in 3.20 but is unused so far. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVJCfoGCrR//JCVInAQIfvxAAhVeEKyhroIGiuCmylWK/TdXja+xO46g+ hkrijO0cPB5C7K45AW2a2aCUM0jSjr81dUprQ/uojr3xXxnJ59t7tDAXpKpFy8xi 5gb/wd/Cea90RtR1mUnNr/+P1sJKemcvmhCuib7111E5wd/s617bLd1+zgCuHguj g733GjDE7SUSTEStviDg963pn+l2IartjhRPhAKmGWiLZA7RiWe35pzDTZGCApnd yfZafXxn4IeUcxQUT6lAsW7xShzCUI2CZ8nZ4tG6YcyR2UNB5BVrPb1BAm6Eb28C 1WmyjnAAyXxc6pqPTalO+JctpS7ujjbtwlOOwgthKyKMfpFnqyavablDl6GvtHn8 NIa3HdnKQTXl9/nRXCvIjeWDyaZEZ5ueacfhMm4PWRSIkqKFVgwY18nNkOul9fuz 0UD9EuN0PPHV2hCIp9Kl3Jju5pi2EEzCt/Vn0YGsZTZuVOfREZ3izDtyKFg1tjif AJ5kFRc1X+6hXNDUWUOmLOnjBvupbq2axFbLeAzQxla/O/0pwHWhiuqXu3uB4six 1Hlgt7yI7pob86VcQKTCg1v8kOvQTEuL2BtUWkCpbyrVSafYRVKwlUNnQlmu5F3c sL14hhK9QSHyCmJ7yKchY104QVKmN8v3ks8PyUNoPxq57ChH4E6FVAZpMz08uF5V mIWREpeIPNw= =ELLq -----END PGP SIGNATURE----- Merge tag 'iommu-config-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC/iommu configuration update from Arnd Bergmann: "The iomm-config branch contains work from Will Deacon, quoting his description: This series adds automatic IOMMU and DMA-mapping configuration for OF-based DMA masters described using the generic IOMMU devicetree bindings.

as I thought it might be. I'm pushing this in now. This will allow Thomas to debug his irq work for 3.20. This adds two new features: 1) Allow traceopoints to be enabled right after mm_init(). By passing in the trace_event= kernel command line parameter, tracepoints can be enabled at boot up. For debugging things like the initialization of interrupts, it is needed to have tracepoints enabled very early. People have asked about this before and this has been on my todo list. As it can be helpful for Thomas to debug his upcoming 3.20 IRQ work, I'm pushing this now. This way he can add tracepoints into the IRQ set up and have users enable them when things go wrong. 2) Have the tracepoints printed via printk() (the console) when they are triggered. If the irq code locks up or reboots the box, having the tracepoint output go into the kernel ring buffer is useless for debugging. But being able to add the tp_printk kernel command line option along with the trace_event= option will have these tracepoints printed as they occur, and that can be really useful for debugging early lock up or reboot problems. This code is not that intrusive and it passed all my tests. Thomas tried them out too and it works for his needs.

net: Allow FIXED_PHY to be modular.
Otherwise we get things like: warning: (NET_DSA_BCM_SF2 && BCMGENET && SYSTEMPORT) selects FIXED_PHY which has unmet direct dependencies (NETDEVICES && PHYLIB=y) In order to make this work we have to rename fixed.c to fixed_phy.c because the regulator drivers already have a module named "fixed.o".
