2016-09-07Drivers: hv: vmbus: suppress some "hv_vmbus: Unknown GUID" warningsDexuan Cui
Some VMBus devices are not needed by Linux guest[1][2], and, VMBus channels of Hyper-V Sockets don't really mean usual synthetic devices, so let's suppress the warnings for them.

2016-09-07jump_labels: Allow array initialisersCatalin Marinas
The static key API is currently designed around single variable definitions. There are cases where an array of static keys is desirable, so extend the API to allow this rather than using the internal static key implementation directly.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree. Most relevant updates are the removal of per-conntrack timers to use a workqueue/garbage collection approach instead from Florian Westphal, the hash and numgen expression for nf_tables from Laura Garcia, updates on nf_tables hash set to honor the NLM_F_EXCL flag, removal of ip_conntrack sysctl and many other incremental updates on our Netfilter codebase. More specifically, they are: 1) Retrieve only 4 bytes to fetch ports in case of non-linear skb transport area in dccp, sctp, tcp, udp and udplite protocol conntrackers, from Gao Feng. 2) Missing whitespace on error message in physdev match, from Hangbin Liu. 3) Skip redundant IPv4 checksum calculation in nf_dup_ipv4, from Liping Zhang. 4) Add nf_ct_expires() helper function and use it, from Florian Westphal. 5) Replace opencoded nf_ct_kill() call in IPVS conntrack support, also from Florian. 6) Rename nf_tables set implementation to nft_set_{name}.c 7) Introduce the hash expression to allow arbitrary hashing of selector concatenations, from Laura Garcia Liebana. 8) Remove ip_conntrack sysctl backward compatibility code, this code has been around for long time already, and we have two interfaces to do this already: nf_conntrack sysctl and ctnetlink. 9) Use nf_conntrack_get_ht() helper function whenever possible, instead of opencoding fetch of hashtable pointer and size, patch from Liping Zhang. 10) Add quota expression for nf_tables. 11) Add number generator expression for nf_tables, this supports incremental and random generators that can be combined with maps, very useful for load balancing purpose, again from Laura Garcia Liebana. 12) Fix a typo in a debug message in FTP conntrack helper, from Colin Ian King. 13) Introduce a nft_chain_parse_hook() helper function to parse chain hook configuration, this is used by a follow up patch to perform better chain update validation. 14) Add rhashtable_lookup_get_insert_key() to rhashtable and use it from the nft_set_hash implementation to honor the NLM_F_EXCL flag. 15) Missing nulls check in nf_conntrack from nf_conntrack_tuple_taken(), patch from Florian Westphal. 16) Don't use the DYING bit to know if the conntrack event has been already delivered, instead a state variable to track event re-delivery states, also from Florian. 17) Remove the per-conntrack timer, use the workqueue approach that was discussed during the NFWS, from Florian Westphal. 18) Use the netlink conntrack table dump path to kill stale entries, again from Florian. 19) Add a garbage collector to get rid of stale conntracks, from Florian. 20) Reschedule garbage collector if eviction rate is high. 21) Get rid of the __nf_ct_kill_acct() helper. 22) Use ARPHRD_ETHER instead of hardcoded 1 from ARP logger. 23) Make nf_log_set() interface assertive on unsupported families. ==================== Signed-off-by: David S.

2016-09-06usercopy: fold builtin_const check into inline functionKees Cook
Instead of having each caller of check_object_size() need to remember to check for a const size parameter, move the check into check_object_size() itself. This actually matches the original implementation in PaX, though this commit cleans up the now-redundant builtin_const() calls in the various architectures.

2016-09-06ARM: 8611/1: l2x0: add PMU supportMark Rutland
The L2C-220 (AKA L220) and L2C-310 (AKA PL310) cache controllers feature a Performance Monitoring Unit (PMU), which can be useful for tuning and/or debugging. This hardware is always present and the relevant registers are accessible to non-secure accesses. Thus, no special firmware interface is necessary. This patch adds support for the PMU, plugging into the usual perf infrastructure. The overflow interrupt is not always available (e.g. on RealView PBX A9 it is not wired up at all), and the hardware counters saturate, so the driver does not make use of this. Instead, the driver periodically polls and reset counters as required to avoid losing events due to saturation.

2016-09-05efi/libstub: Introduce ExitBootServices helperJeffrey Hugo
The spec allows ExitBootServices to fail with EFI_INVALID_PARAMETER if a race condition has occurred where the EFI has updated the memory map after the stub grabbed a reference to the map. The spec defines a retry proceedure with specific requirements to handle this scenario. This scenario was previously observed on x86 - commit d3768d885c6c ("x86, efi: retry ExitBootServices() on failure") but the current fix is not spec compliant and the scenario is now observed on the Qualcomm Technologies QDF2432 via the FDT stub which does not handle the error and thus causes boot failures. The user will notice the boot failure as the kernel is not executed and the system may drop back to a UEFI shell, but will be unresponsive to input and the system will require a power cycle to recover. Add a helper to the stub library that correctly adheres to the spec in the case of EFI_INVALID_PARAMETER from ExitBootServices and can be universally used across all stub implementations.

efi_get_memory_map() allocates a buffer to store the memory map that it retrieves. This buffer may need to be reused by the client after ExitBootServices() is called, at which point allocations are not longer permitted. To support this usecase, provide the allocated buffer size back to the client, and allocate some additional headroom to account for any reasonable growth in the map that is likely to happen between the call to efi_get_memory_map() and the client reusing the buffer.

2016-09-05iommu/amd: Introduce amd_iommu_update_ga()Suravee Suthikulpanit
Introduces a new IOMMU API, amd_iommu_update_ga(), which allows KVM (SVM) to update existing posted interrupt IOMMU IRTE when load/unload vcpu. Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2016-09-05iommu/amd: Adding GALOG interrupt handlerSuravee Suthikulpanit
This patch adds AMD IOMMU guest virtual APIC log (GALOG) handler. When IOMMU hardware receives an interrupt targeting a blocking vcpu, it creates an entry in the GALOG, and generates an interrupt to notify the AMD IOMMU driver. At this point, the driver processes the log entry, and notify the SVM driver via the registered iommu_ga_log_notifier function.

2016-09-05efi: Make for_each_efi_memory_desc_in_map() cope with running on XenJan Beulich
While commit 55f1ea15216 ("efi: Fix for_each_efi_memory_desc_in_map() for empty memmaps") made an attempt to deal with empty memory maps, it didn't address the case where the map field never gets set, as is apparently the case when running under Xen.

2016-09-05locking/barriers: Don't use sizeof(void) in lockless_dereference()Johannes Berg
My previous commit: 112dc0c8069e ("locking/barriers: Suppress sparse warnings in lockless_dereference()") caused sparse to complain that (in radix-tree.h) we use sizeof(void) since that rcu_dereference()s a void *. Really, all we need is to have the expression *p in here somewhere to make sure p is a pointer type, and sizeof(*p) was the thing that came to my mind first to make sure that's done without really doing anything at runtime. Another thing I had considered was using typeof(*p), but obviously we can't just declare a typeof(*p) variable either, since that may end up being void. Declaring a variable as typeof(*p)* gets around that, and still checks that typeof(*p) is valid, so do that. This type construction can't be done for _________p1 because that will actually be used and causes sparse address space warnings, so keep a separate unused variable for it.
