Code which initializes the "clk_init_data.ops" checks pll->rate_table before that field is ever assigned to so it always picks "clk_pll1416x_min_ops".

Rather embarrassingly, our futex() FUTEX_WAKE_OP implementation doesn't explicitly set the return value on the non-faulting path and instead leaves it holding the result of the underlying atomic operation. This means that any FUTEX_WAKE_OP atomic operation which computes a non-zero value will be reported as having failed. Regrettably, I wrote the buggy code back in 2011 and it was upstreamed as part of the initial arm64 support in 2012. The reasons we appear to get away with this are: 1. FUTEX_WAKE_OP is rarely used and therefore doesn't appear to get exercised by futex() test applications 2. If the result of the atomic operation is zero, the system call behaves correctly 3. Prior to version 2.25, the only operation used by GLIBC set the futex to zero, and therefore worked as expected. From 2.25 onwards, FUTEX_WAKE_OP is not used by GLIBC at all. Fix the implementation by ensuring that the return value is either 0 to indicate that the atomic operation completed successfully, or -EFAULT if we encountered a fault when accessing the user mapping.

Thomas-Mich Richter reported he triggered a WARN()ing from event_function_local() on his s390. The problem boils down to: CPU-A CPU-B perf_event_overflow() perf_event_disable_inatomic() @pending_disable = 1 irq_work_queue(); sched-out event_sched_out() @pending_disable = 0 sched-in perf_event_overflow() perf_event_disable_inatomic() @pending_disable = 1; irq_work_queue(); // FAILS irq_work_run() perf_pending_event() if (@pending_disable) perf_event_disable_local(); // WHOOPS The problem exists in generic, but s390 is particularly sensitive because it doesn't implement arch_irq_work_raise(), nor does it call irq_work_run() from it's PMU interrupt handler (nor would that be sufficient in this case, because s390 also generates perf_event_overflow() from pmu::stop). Add to that the fact that s390 is a virtual architecture and (virtual) CPU-A can stall long enough for the above race to happen, even if it would self-IPI. Adding a irq_work_sync() to event_sched_in() would work for all hardare PMUs that properly use irq_work_run() but fails for software PMUs. Instead encode the CPU number in @pending_disable, such that we can tell which CPU requested the disable. This then allows us to detect the above scenario and even redirect the IPI to make up for the failed queue.

commit 5b0d6210 ("mmc: sdhci-omap: Add platform specific reset callback") skips data resets during tuning operation. Because of this, a data error or data finish interrupt might still arrive after a command error has been handled and the mrq ended. This ends up with a "mmc0: Got data interrupt 0x00000002 even though no data operation was in progress" error message. Fix this by adding a platform specific callback for sdhci_irq. Mark the mrq as a failure but wait for a data interrupt instead of calling finish_mrq().

Since commit 648e9218 ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are unconditionally gated off. Unfortunately this will break systems where these clocks are used for external purposes beyond the kernel's knowledge. Fix it by implementing a system specific quirk to mark the necessary pmc_plt_clks as critical.

During a safe hot remove, the OS powers off the slot, which may cause a Data Link Layer State Changed event. The slot has already been set to OFF_STATE, so that event results in re-enabling the device, making it impossible to safely remove it. Clear out the Presence Detect Changed and Data Link Layer State Changed events when the disabled slot has settled down. It is still possible to re-enable the device if it remains in the slot after pressing the Attention Button by pressing it again. Fixes the problem that Micah reported below: an NVMe drive power button may not actually turn off the drive.

Now that we allow drivers to always need to set larger than required DMA masks we need to be a little more careful in the sun4v PCI iommu driver to chose when to select the ATU support - a larger DMA mask can be set even when the platform does not support ATU, so we always have to check if it is avaiable before using it. Add a little helper for that and use it in all the places where we make ATU usage decisions based on the DMA mask.
