2016-08-16drm/kms: Nuke dirty_info propertyDaniel Vetter
It was added way back together with the dirty_fb ioctl, but neither generic xfree86-modesetting nor the vmware driver use it. Everyone is supposed to just unconditionally call the dirtyfb when they do frontbuffer rendering. And since unused uabi is bad uabi (there's reasons we require open source userspace for everything) let's nuke this.

2016-08-16drm/i915: Embrace the race in busy-ioctlChris Wilson
Daniel Vetter proposed a new challenge to the serialisation inside the busy-ioctl that exposed a flaw that could result in us reporting the wrong engine as being busy. If the request is reallocated as we test its busyness and then reassigned to this object by another thread, we would not notice that the test itself was incorrect. We are faced with a choice of using __i915_gem_active_get_request_rcu() to first acquire a reference to the request preventing the race, or to acknowledge the race and accept the limitations upon the accuracy of the busy flags. Note that we guarantee that we never falsely report the object as idle (providing userspace itself doesn't race), and so the most important use of the busy-ioctl and its guarantees are fulfilled.

2016-08-15gre: set inner_protocol on xmitSimon Horman
Ensure that the inner_protocol is set on transmit so that GSO segmentation, which relies on that field, works correctly. This is achieved by setting the inner_protocol in gre_build_header rather than each caller of that function. It ensures that the inner_protocol is set when gre_fb_xmit() is used to transmit GRE which was not previously the case. I have observed this is not the case when OvS transmits GRE using lwtunnel metadata (which it always does).

2016-08-15USB: bcma: support old USB 2.0 controller on Northstar devicesRafał Miłecki
Currently bcma-hcd driver handles 3 different bcma cores: 1) BCMA_CORE_USB20_HOST (0x819) 2) BCMA_CORE_NS_USB20 (0x504) 3) BCMA_CORE_NS_USB30 (0x505) The first one was introduced years ago and so far was used on MIPS devices only. All Northstar (ARM) devices were using other two cores which allowed easy implementation of separated initialization paths. It seems however Broadcom decided to reuse this old USB 2.0 controller on some recently introduced cheaper Northstar BCM53573 SoCs. I noticed this on Tenda AC9 (based on BCM47189B0 belonging to BCM53573 family). There is no difference in this old controller core identification between MIPS and ARM devices: they share the same id and revision. We need different controller initialization procedure however. To handle this add a check for architecture and implement required initialization for ARM case.

2016-08-13net: remove type_check from dev_get_nest_level()Sabrina Dubroca
The idea for type_check in dev_get_nest_level() was to count the number of nested devices of the same type (currently, only macvlan or vlan devices). This prevented the false positive lockdep warning on configurations such as: eth0 <--- macvlan0 <--- vlan0 <--- macvlan1 However, this doesn't prevent a warning on a configuration such as: eth0 <--- macvlan0 <--- vlan0 eth1 <--- vlan1 <--- macvlan1 In this case, all the locks end up with a nesting subclass of 1, so lockdep thinks that there is still a deadlock: - in the first case we have (macvlan_netdev_addr_lock_key, 1) and then take (vlan_netdev_xmit_lock_key, 1) - in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then take (macvlan_netdev_addr_lock_key, 1) By removing the linktype check in dev_get_nest_level() and always incrementing the nesting depth, lockdep considers this configuration valid.

2016-08-12bpf: fix bpf_skb_in_cgroup helper namingDaniel Borkmann
While hashing out BPF's current_task_under_cgroup helper bits, it came to discussion that the skb_in_cgroup helper name was suboptimally chosen. Tejun says: So, I think in_cgroup should mean that the object is in that particular cgroup while under_cgroup in the subhierarchy of that cgroup. Let's rename the other subhierarchy test to under too. I think that'd be a lot less confusing going forward. [...] It's more intuitive and gives us the room to implement the real "in" test if ever necessary in the future. Since this touches uapi bits, we need to change this as long as v4.8 is not yet officially released. Thus, change the helper enum and rename related bits.

2016-08-13ACPICA: OSL: Fix a regression that old GCC requires a workaround for strchr()Lv Zheng
ACPICA commit be836c36454a624a4fb1d17234080ef8c07993fc There is a GCC false-warning issue on specific GCC versions that "strchr" will be preprocessed and extracted to contain !__buildin_constant_p() checker and it surely is a constant logical value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a warning. The regression is triggered after the standard headers are re-ordered in the EFI porting task. This patch fixes this regression by moving the workaround to a new position after including all other standard headers.

2016-08-13ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headersLv Zheng
ACPICA commit a760a98ec84b1ec782e0bff5f6612af6fb89c10c Originally compiler specific headers are included by the host-specific headers. This makes build configuration management very inconvenient. And many inclusion order issues can be hidden accross different host OSes. It will then likely that some host builds will be broken just because of fixing some inclusion order issues for other host builds. This patch splits the compiler-specific header inclusions out of the host-specific headers so that compiler-specific inclusion order issues will not get entangled in the host-specific inclusion orders. Note that intel compiler defines __GNUC__, so this patch contains special handling because acintel.h and acgcc.h should be mutual exclusive.

2016-08-13ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issueLv Zheng
ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09 When /Za is specified, headers of some Windows SDKs contain bugs breaking VC builds, and MSVC9's default SDK is one of such header-buggy library. In order to solve this issue, many VC developers stop using /Za. However we've been asked to have this fixed without removing /Za. In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h> to be the last standard file included by every source file in the projects. This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this issue can be fixed by ensuring that "acapps.h" is always the last standard file included by all of the ACPICA source files. This is in fact also a useful cleanup because applications can only include one header (e.x., acpidump.h) instead of including acapps.h separately. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.

2016-08-13ACPICA: Clib/EFI: Fix wrong order of standard integer types/IO handlesLv Zheng
ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d EFI header should use standard C library stuffs (integer types and IO handles) rather than implementing such standard stuffs. This patch fixes this issue by: 1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n; 2. Defining EFI types using standard integer types and standard IO handles; 3. Tuning header inclusion order and environment definition order; 4. Removing wrong standard header inclusion from ACPICA core files; 5. Moving several application headers from acpidump.h to acenv.h. This patch corrects some of them. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.
