2018-11-07drm/amd/display: Drop reusing drm connector for MSTJerry (Fangzhi) Zuo2-35/+7
[why] It is not safe to keep existing connector while entire topology has been removed. Could lead potential impact to uapi. Entirely unregister all the connectors on the topology, and use a new set of connectors when the topology is plugged back on. [How] Remove the drm connector entirely each time when the corresponding MST topology is gone. When hotunplug a connector (e.g., DP2) 1. Remove connector from userspace. 2. Drop it's reference. When hotplug back on: 1. Detect new topology, and create new connectors. 2. Notify userspace with sysfs hotplug event. 3. Reprobe new connectors, and reassign CRTC from old (e.g., DP2) to new (e.g., DP3) connector.

2018-11-07leds: trigger: Fix sleeping function called from invalid contextBaolin Wang1-16/+4
We will meet below issue due to mutex_lock() is called in interrupt context. The mutex lock is used to protect the pattern trigger data, but before changing new pattern trigger data (pattern values or repeat value) by users, we always cancel the timer firstly to clear previous patterns' performance. That means there is no race in pattern_trig_timer_function(), so we can drop the mutex lock in pattern_trig_timer_function() to avoid this issue. Moreover we can move the timer cancelling into mutex protection, since there is no deadlock risk if we remove the mutex lock in pattern_trig_timer_function().

With drivers that are settting a virtual boundary constrain, we are seeing a lot of bio splitting and smaller I/Os being submitted to the driver. This happens because the bio gap detection code does not account cases where PAGE_SIZE - 1 is bigger than queue_virt_boundary() and thus will split the bio unnecessarily.

2018-11-07Btrfs: fix missing delayed iputs on unmountOmar Sandoval1-36/+15
There's a race between close_ctree() and cleaner_kthread(). close_ctree() sets btrfs_fs_closing(), and the cleaner stops when it sees it set, but this is racy; the cleaner might have already checked the bit and could be cleaning stuff. In particular, if it deletes unused block groups, it will create delayed iputs for the free space cache inodes. As of "btrfs: don't run delayed_iputs in commit", we're no longer running delayed iputs after a commit. Therefore, if the cleaner creates more delayed iputs after delayed iputs are run in btrfs_commit_super(), we will leak inodes on unmount and get a busy inode crash from the VFS. Fix it by parking the cleaner before we actually close anything. Then, any remaining delayed iputs will always be handled in btrfs_commit_super(). This also ensures that the commit in close_ctree() is really the last commit, so we can get rid of the commit in cleaner_kthread(). The fstest/generic/475 followed by 476 can trigger a crash that manifests as a slab corruption caused by accessing the freed kthread structure by a wake up function.

2018-11-07i40e: enable NETIF_F_NTUPLE and NETIF_F_HW_TC at driver loadJacob Keller1-3/+3
The assignment of the feature flag NETIF_F_NTUPLE and NETIF_F_HW_TC occurs prior to the initial setup of the local hw_features variable. This means the features are set as user-changeable, but are not set in the currently active feature list. This results in the features being disabled at the driver's initial load. Move the assignment after the initial assignment of hw_features, and assign to the local variable. This ensures that NETIF_F_NTUPLE and NETIF_F_HW_TC are marked as user-changeable, and also enables them by default when the driver loads.

2018-11-07i40e: restore NETIF_F_GSO_IPXIP[46] to netdev featuresJacob Keller1-0/+2
Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for outer checksum", 2017-04-06) the i40e driver has not reported support for IP-in-IP offloads. This likely occurred due to a bad rebase, as the commit extracts hw_enc_features into its own variable. As part of this change, it dropped the NETIF_F_FSO_IPXIP flags from the netdev->hw_enc_features. This was unfortunately not caught during code review. Fix this by adding back the missing feature flags. For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a ("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20), replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT. NETIF_F_GSO_IPXIP6 was added in commit bf2d1df39502 ("intel: Add support for IPv6 IP-in-IP offload", 2016-05-20).

2018-11-07rtc: cmos: Do not export alarm rtc_ops when we do not support alarmsHans de Goede1-4/+12
When there is no IRQ configured for the RTC, the rtc-cmos code does not support alarms, all alarm rtc_ops fail with -EIO / -EINVAL. The rtc-core expects a rtc driver which does not support rtc alarms to not have alarm ops at all. Otherwise the wakealarm sysfs attr will read as empty rather then returning an error, making it impossible for userspace to find out beforehand if alarms are supported. A system without an IRQ for the RTC before this patch: [root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm [root@localhost ~]# After this patch: [root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm cat: /sys/class/rtc/rtc0/wakealarm: No such file or directory [root@localhost ~]# This fixes gnome-session + systemd trying to use suspend-then-hibernate, which causes systemd to abort the suspend when writing the RTC alarm fails.

2018-11-07Documentation: cpu-freq: Frequencies aren't always sortedViresh Kumar1-3/+5
The order in which the frequencies are displayed in cpufreq stats depends on the order in which the frequencies were sorted in the frequency table provided to cpufreq core by the cpufreq driver. They can be completely unsorted as well. The documentation's claim that the stats will be sorted in descending order is hence incorrect and here is an attempt to fix it.

2018-11-07KVM: PPC: Move and undef TRACE_INCLUDE_PATH/FILEScott Wood4-8/+27
TRACE_INCLUDE_PATH and TRACE_INCLUDE_FILE are used by <trace/define_trace.h>, so like that #include, they should be outside #ifdef protection. They also need to be #undefed before defining, in case multiple trace headers are included by the same C file. This became the case on book3e after commit cf4a6085151a ("powerpc/mm: Add missing tracepoint for tlbie"), leading to the following build error: CC arch/powerpc/kvm/powerpc.o In file included from arch/powerpc/kvm/powerpc.c:51:0: arch/powerpc/kvm/trace.h:9:0: error: "TRACE_INCLUDE_PATH" redefined [-Werror] #define TRACE_INCLUDE_PATH . ^ In file included from arch/powerpc/kvm/../mm/mmu_decl.h:25:0, from arch/powerpc/kvm/powerpc.c:48: ./arch/powerpc/include/asm/trace.h:224:0: note: this is the location of the previous definition #define TRACE_INCLUDE_PATH asm ^ cc1: all warnings being treated as errors Reported-by: Christian Zigotzky <[email protected]> Signed-off-by: Scott Wood <[email protected]> Signed-off-by: Michael Ellerman <[email protected]>

This patch fixes a issue which doesn't work extension and clone mode because some CRTC devices don't provide frame counter value properly. - Fix lack of fbdev on Rinato and trats boards. . This patch considers for connector to be registered by DSI after DRM device is registered, and also it makes fbdev initializaion to be done even if no connector at the moment. - Check for dsi->panel object correctly . This patch fixes checking for dsi->panel. of_drm_find_panel function returns panel object or error value so error value should be checked using IS_ERR macro.
