2021-04-30ocfs2: map flags directly in flags_to_o2dlm()Joseph Qi
Use macro map_flag() is tricky and coccicheck outputs the following warning: fs/ocfs2/stack_o2cb.c:69:5-16: Unneeded variable: "o2dlm_flags" So map flags directly in flags_to_o2dlm() to make coccicheck happy.

2021-04-30ia64: ensure proper NUMA distance and possible map initializationValentin Schneider
John Paul reported a warning about bogus NUMA distance values spurred by commit: 620a6dc40754 ("sched/topology: Make sched_init_numa() use a set for the deduplicating sort") In this case, the afflicted machine comes up with a reported 256 possible nodes, all of which are 0 distance away from one another. This was previously silently ignored, but is now caught by the aforementioned commit. The culprit is ia64's node_possible_map which remains unchanged from its initialization value of NODE_MASK_ALL. In John's case, the machine doesn't have any SRAT nor SLIT table, but AIUI the possible map remains untouched regardless of what ACPI tables end up being parsed. Thus, !online && possible nodes remain with a bogus distance of 0 (distances \in [0, 9] are "reserved and have no meaning" as per the ACPI spec). Follow x86 / drivers/base/arch_numa's example and set the possible map to the parsed map, which in this case seems to be the online map.

2021-04-30tracing: Restructure trace_clock_global() to never blockSteven Rostedt (VMware)
It was reported that a fix to the ring buffer recursion detection would cause a hung machine when performing suspend / resume testing. The following backtrace was extracted from debugging that case: Call Trace: trace_clock_global+0x91/0xa0 __rb_reserve_next+0x237/0x460 ring_buffer_lock_reserve+0x12a/0x3f0 trace_buffer_lock_reserve+0x10/0x50 __trace_graph_return+0x1f/0x80 trace_graph_return+0xb7/0xf0 ? trace_clock_global+0x91/0xa0 ftrace_return_to_handler+0x8b/0xf0 ? pv_hash+0xa0/0xa0 return_to_handler+0x15/0x30 ? ftrace_graph_caller+0xa0/0xa0 ? trace_clock_global+0x91/0xa0 ? __rb_reserve_next+0x237/0x460 ? ring_buffer_lock_reserve+0x12a/0x3f0 ? trace_event_buffer_lock_reserve+0x3c/0x120 ? trace_event_buffer_reserve+0x6b/0xc0 ? trace_event_raw_event_device_pm_callback_start+0x125/0x2d0 ? dpm_run_callback+0x3b/0xc0 ? pm_ops_is_empty+0x50/0x50 ? platform_get_irq_byname_optional+0x90/0x90 ? trace_device_pm_callback_start+0x82/0xd0 ? dpm_run_callback+0x49/0xc0 With the following RIP: RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200 Since the fix to the recursion detection would allow a single recursion to happen while tracing, this lead to the trace_clock_global() taking a spin lock and then trying to take it again: ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* lock taken */ (something else gets traced by function graph tracer) ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* DEAD LOCK! */ Tracing should *never* block, as it can lead to strange lockups like the above. Restructure the trace_clock_global() code to instead of simply taking a lock to update the recorded "prev_time" simply use it, as two events happening on two different CPUs that calls this at the same time, really doesn't matter which one goes first. Use a trylock to grab the lock for updating the prev_time, and if it fails, simply try again the next time. If it failed to be taken, that means something else is already updating it.

ssh://git.freedesktop.org/git/tegra/linux into drm-next drm/tegra: Changes for v5.13-rc1 The changes this time around contain a couple of fixes for host1x along with some improvements for Tegra DRM. Most notably the Tegra DRM driver now supports the hardware cursor on Tegra186 and later, more correctly reflects the capabilities of the display pipelines on various Tegra SoC generations and knows how to deal with the dGPU sector layout by using framebuffer modifiers.

2021-04-29rtc: omap: use rtc_write to access OMAP_RTC_OSC_REGDario Binacchi
The RTC_OSC_REG register is 32-bit, but the useful information is found in the 7 least significant bits (bits 7-31 are reserved). And in fact, as you can see from the code, all read accesses are 8-bit, as well as some writes. Let's make sure all writes are 8-bit. Moreover, in contexts where consecutive reads / writes after the busy check must take place within 15 us, it is better not to waste time on useless accesses.

2021-04-29rtc: rtc_update_irq_enable: rework UIE emulationAlexandre Belloni
Now that the core is aware of whether alarms are available, it is possible to decide whether UIE emulation is required before actually trying to set the alarm. This greatly simplifies rtc_update_irq_enable because there is now only one error value to track and is not relying on the return value of __rtc_set_alarm anymore.
