2019-09-04binder: Add default binder devices through binderfs when configuredHridya Valsaraju
Currently, since each binderfs instance needs its own private binder devices, every time a binderfs instance is mounted, all the default binder devices need to be created via the BINDER_CTL_ADD IOCTL. This patch aims to add a solution to automatically create the default binder devices for each binderfs instance that gets mounted. To achieve this goal, when CONFIG_ANDROID_BINDERFS is set, the default binder devices specified by CONFIG_ANDROID_BINDER_DEVICES are created in each binderfs instance instead of global devices being created by the binder driver.

2019-09-04binder: Validate the default binderfs device names.Hridya Valsaraju
Length of a binderfs device name cannot exceed BINDERFS_MAX_NAME. This patch adds a check in binderfs_init() to ensure the same for the default binder devices that will be created in every binderfs instance.

Time has come to get rid of the old eeprom driver. The at24 driver should be used instead. So mark the eeprom driver as deprecated and give users some time to migrate.

2019-09-03coresight: tmc-etr: Fix perf_data checkYabin Cui
When tracing etm data of multiple threads on multiple cpus through perf interface, each cpu has a unique etr_perf_buffer while sharing the same etr device. There is no guarantee that the last cpu starts etm tracing also stops last. This makes perf_data check fail. Fix it by checking etr_buf instead of etr_perf_buffer. Also move the code setting and clearing perf_buf to more suitable places.

TMC etr always copies all available data to perf aux buffer, which may exceed the available space in perf aux buffer. It isn't suitable for not-snapshot mode, because: 1) It may overwrite previously written data. 2) It may make the perf_event_mmap_page->aux_head report having more or less data than the reality. So change to only copy the latest data fitting the available space in perf aux buffer.

2019-09-03coresight: etm4x: Use explicit barriers on enable/disableAndrew Murray
Synchronization is recommended before disabling the trace registers to prevent any start or stop points being speculative at the point of disabling the unit (section 7.3.77 of ARM IHI 0064D). Synchronization is also recommended after programming the trace registers to ensure all updates are committed prior to normal code resuming (section 4.3.7 of ARM IHI 0064D). Let's ensure these syncronization points are present in the code and clearly commented. Note that we could rely on the barriers in CS_LOCK and coresight_disclaim_device_unlocked or the context switch to user space - however coresight may be of use in the kernel. On armv8 the mb macro is defined as dsb(sy) - Given that the etm4x is only used on armv8 let's directly use dsb(sy) instead of mb(). This removes some ambiguity and makes it easier to correlate the code with the TRM.

This change enables the use of SW timestamping on the Raspberry Pi 4. bcmgenet's transmit function bcmgenet_xmit() implements software timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the SOF_TIMESTAMPING_TX_SOFTWARE capability is announced.

2019-08-31net: aquantia: fix out of memory condition on rx sideDmitry Bogdanov
On embedded environments with hard memory limits it is a normal although rare case when skb can't be allocated on rx part under high traffic. In such OOM cases napi_complete_done() was not called. So the napi object became in an invalid state like it is "scheduled". Kernel do not re-schedules the poll of that napi object. Consequently, kernel can not remove that object the system hangs on `ifconfig down` waiting for a poll. We are fixing this by gracefully closing napi poll routine with correct invocation of napi_complete_done. This was reproduced with artificially failing the allocation of skb to simulate an "out of memory" error case and check that traffic does not get stuck.

2019-08-31net: aquantia: linkstate irq should be oneshotIgor Russkikh
Declaring threaded irq handler should also indicate the irq is oneshot. It is oneshot indeed, because HW implements irq automasking on trigger. Not declaring this causes some kernel configurations to fail on interface up, because request_threaded_irq returned an err code. The issue was originally hidden on normal x86_64 configuration with latest kernel, because depending on interrupt controller, irq driver added ONESHOT flag on its own. Issue was observed on older kernels (4.14) where no such logic exists.
