Add support to hikey dts for the syscon-reboot-mode driver. After trying an approach using a sram driver and node, a number of issues cropped up which would make it so we would be duplicating a lot of extra syscon infrastructure in order to support mfds on sram. After talking with Bjorn, using the syscon driver for this seems like an better choice.

2016-08-24nvme: Fix nvme_get/set_features() with a NULL result pointerAndy Lutomirski1-2/+2
nvme_set_features() callers seem to expect that passing NULL as the result pointer is acceptable. Teach nvme_set_features() not to try to write to the NULL address. For symmetry, make the same change to nvme_get_features(), despite the fact that all current callers pass a valid result pointer. I assume that this bug hasn't been reported in practice because the callers that pass NULL are all in the SCSI translation layer and no one uses the relevant operations.

2016-08-24drm/tegra: dsi: Enhance runtime power managementThierry Reding3-39/+69
The MIPI DSI output on Tegra SoCs requires some external logic to calibrate the MIPI pads before a video signal can be transmitted. This MIPI calibration logic requires to be powered on while the MIPI pads are being used, which is currently done as part of the DSI driver's probe implementation. This is suboptimal because it will leave the MIPI calibration logic powered up even if the DSI output is never used. On Tegra114 and earlier this behaviour also causes the driver to hang while trying to power up the MIPI calibration logic because the power partition that contains the MIPI calibration logic will be powered on by the display controller at output pipeline configuration time. Thus the power up sequence for the MIPI calibration logic happens before it's power partition is guaranteed to be enabled. Fix this by splitting up the API into a request/free pair of functions that manage the runtime dependency between the DSI and the calibration modules (no registers are accessed) and a set of enable, calibrate and disable functions that program the MIPI calibration logic at points in time where the power partition is really enabled. While at it, make sure that the runtime power management also works in ganged mode, which is currently also broken.

2016-08-24perf/core: Use this_cpu_ptr() when stopping AUX eventsWill Deacon1-1/+1
When tearing down an AUX buf for an event via perf_mmap_close(), __perf_event_output_stop() is called on the event's CPU to ensure that trace generation is halted before the process of unmapping and freeing the buffer pages begins. The callback is performed via cpu_function_call(), which ensures that it runs with interrupts disabled and is therefore not preemptible. Unfortunately, the current code grabs the per-cpu context pointer using get_cpu_ptr(), which unnecessarily disables preemption and doesn't pair the call with put_cpu_ptr(), leading to a preempt_count() imbalance and a BUG when freeing the AUX buffer later on: WARNING: CPU: 1 PID: 2249 at kernel/events/ring_buffer.c:539 __rb_free_aux+0x10c/0x120 Modules linked in: [...] Call Trace: [<ffffffff813379dd>] dump_stack+0x4f/0x72 [<ffffffff81059ff6>] __warn+0xc6/0xe0 [<ffffffff8105a0c8>] warn_slowpath_null+0x18/0x20 [<ffffffff8112761c>] __rb_free_aux+0x10c/0x120 [<ffffffff81128163>] rb_free_aux+0x13/0x20 [<ffffffff8112515e>] perf_mmap_close+0x29e/0x2f0 [<ffffffff8111da30>] ? perf_iterate_ctx+0xe0/0xe0 [<ffffffff8115f685>] remove_vma+0x25/0x60 [<ffffffff81161796>] exit_mmap+0x106/0x140 [<ffffffff8105725c>] mmput+0x1c/0xd0 [<ffffffff8105cac3>] do_exit+0x253/0xbf0 [<ffffffff8105e32e>] do_group_exit+0x3e/0xb0 [<ffffffff81068d49>] get_signal+0x249/0x640 [<ffffffff8101c273>] do_signal+0x23/0x640 [<ffffffff81905f42>] ? _raw_write_unlock_irq+0x12/0x30 [<ffffffff81905f69>] ? _raw_spin_unlock_irq+0x9/0x10 [<ffffffff81901896>] ? __schedule+0x2c6/0x710 [<ffffffff810022a4>] exit_to_usermode_loop+0x74/0x90 [<ffffffff81002a56>] prepare_exit_to_usermode+0x26/0x30 [<ffffffff81906d1b>] retint_user+0x8/0x10 This patch uses this_cpu_ptr() instead of get_cpu_ptr(), since preemption is already disabled by the caller.

2016-08-24timekeeping: Cap array access in timekeeping_debugJohn Stultz1-2/+7
It was reported that hibernation could fail on the 2nd attempt, where the system hangs at hibernate() -> syscore_resume() -> i8237A_resume() -> claim_dma_lock(), because the lock has already been taken. However there is actually no other process would like to grab this lock on that problematic platform. Further investigation showed that the problem is triggered by setting /sys/power/pm_trace to 1 before the 1st hibernation. Since once pm_trace is enabled, the rtc becomes unmeaningful after suspend, and meanwhile some BIOSes would like to adjust the 'invalid' RTC (e.g, smaller than 1970) to the release date of that motherboard during POST stage, thus after resumed, it may seem that the system had a significant long sleep time which is a completely meaningless value. Then in timekeeping_resume -> tk_debug_account_sleep_time, if the bit31 of the sleep time happened to be set to 1, fls() returns 32 and we add 1 to sleep_time_bin[32], which causes an out of bounds array access and therefor memory being overwritten. As depicted by System.map: 0xffffffff81c9d080 b sleep_time_bin 0xffffffff81c9d100 B dma_spin_lock the dma_spin_lock.val is set to 1, which caused this problem. This patch adds a sanity check in tk_debug_account_sleep_time() to ensure we don't index past the sleep_time_bin array.

2016-08-23um: Don't discard .text.exit sectionAndrey Ryabinin1-1/+1
Commit e41f501d3912 ("vmlinux.lds: account for destructor sections") added '.text.exit' to EXIT_TEXT which is discarded at link time by default. This breaks compilation of UML: `.text.exit' referenced in section `.fini_array' of /usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o): defined in discarded section `.text.exit' of /usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o) Apparently UML doesn't want to discard exit text, so let's place all EXIT_TEXT sections in .exit.text.

2016-08-23ubifs: Fix xattr generic handler usageRichard Weinberger1-1/+4
UBIFS uses full names to work with xattrs, therefore we have to use xattr_full_name() to obtain the xattr prefix as string.

2016-08-23ubifs: Fix assertion in layout_in_gaps()Vincent Stehlé1-1/+1
An assertion in layout_in_gaps() verifies that the gap_lebs pointer is below the maximum bound. When computing this maximum bound the idx_lebs count is multiplied by sizeof(int), while C pointers arithmetic does take into account the size of the pointed elements implicitly already. Remove the multiplication to fix the assertion.

2016-08-23iw_cxgb4: Fix cxgb4 arm CQ logic w/IB_CQ_REPORT_MISSED_EVENTSBharat Potnuri2-5/+10
Current cxgb4 arm CQ logic ignores IB_CQ_REPORT_MISSED_EVENTS for request completion notification on a CQ. Due to this ib_poll_handler() assumes all events polled and avoids further iopoll scheduling. This patch adds logic to cxgb4 ib_req_notify_cq() handler to check if CQ is not empty and return accordingly. Based on the return value of ib_req_notify_cq() handler, ib_poll_handler() will schedule a run of iopoll handler.

2016-08-23i40iw: Change mem_resources pointer to a u8Shiraz Saleem1-1/+1
iwdev->mem_resources is incorrectly defined as an unsigned long instead of u8. As a result, the offset into the dynamic allocated structures in i40iw_initialize_hw_resources() is incorrectly calculated and would lead to writing of memory regions outside of the allocated buffer.

* Reuse existing functionality from memdup_user() instead of keeping duplicate source code. This issue was detected by using the Coccinelle software. * The local variable "ret" will be set to an appropriate value a bit later. Thus omit the explicit initialisation at the beginning.
