       - stm32: fix the kernel build by selecting the hierarchical irqdomain
         symbol properly - this happens to be done in the pin control
         framework but whatever, it had dependencies to GPIO so we need to
         apply it here.
      
       - Select the hierarchical IRQ domain also for Xgene.
      
       - Fix wakeups to work on MXC.
      
       - Fix up the device tree binding on Exar that went astray, also add the
         right bindings.
      
       - Fix the unwanted events for edges from the library.
      
       - Fix the unbalanced chanined IRQ on the Tegra.

      Pull clk fixes from Stephen Boyd:
       "A handful of critical fixes for changes introduce this merge window.
      
         - The TI sci_clk_get() API was pretty broken and nobody noticed.
      
         - There were some CPUfreq crashes on C.H.I.P devices because we
           failed to propagate rates up the clk tree.
      
         - Also, the Intel Atom PMC clk driver needs to mark a clk critical if
           the firmware has it enabled already so that audio doesn't get
           killed on Baytrail.
      
         - Gemini devices have a dead serial console because the reset control
           usage in the serial driver assume one method of reset that gemini
           doesn't support (this will be fixed in the next version in the
           reset framework so this is the small fix for -rc series).
      
         - Finally we have two rate calculation fixes, one for Exynos and one
           for Meson SoCs, that fix rate inconsistencies"

      Pull ARM SoC fixes from Arnd Bergmann:
       "This comes a bit later than I planned, and as a consequence is a
        larger than it should be.
      
        Most of the changes are devicetree fixes, across lots of platforms:
        Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic
        Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
      
        Also across many platforms, I applied an older series of simple
        randconfig build fixes. This includes making the CONFIG_MTD_XIP option
        compile again, which had been broken for many years and probably has
        not been missed, but it felt wrong to just remove it completely.
      
        The only other changes are:
      
         - We enable HWSPINLOCK in defconfig to get some Qualcomm boards to
           work out of the box.
      
         - A few regression fixes for Texas Instruments OMAP2+.

      sparc64: Fix exception handling in UltraSPARC-III memcpy. · 0ede1c40
      David S. Miller authored
      Mikael Pettersson reported that some test programs in the strace-4.18
      testsuite cause an OOPS.
      
      After some debugging it turns out that garbage values are returned
      when an exception occurs, causing the fixup memset() to be run with
      bogus arguments.
      
      The problem is that two of the exception handler stubs write the
      successfully copied length into the wrong register.

      arm64: Fix potential race with hardware DBM in ptep_set_access_flags() · 6d332747
      Catalin Marinas authored
      In a system with DBM (dirty bit management) capable agents there is a
      possible race between a CPU executing ptep_set_access_flags() (maybe
      non-DBM capable) and a hardware update of the dirty state (clearing of
      PTE_RDONLY). The scenario:
      
      a) the pte is writable (PTE_WRITE set), clean (PTE_RDONLY set) and old
         (PTE_AF clear)
      b) ptep_set_access_flags() is called as a result of a read access and it
         needs to set the pte to writable, clean and young (PTE_AF set)
      c) a DBM-capable agent, as a result of a different write access, is
         marking the entry as young (setting PTE_AF) and dirty (clearing
         PTE_RDONLY)
      
      The current ptep_set_access_flags() implementation would set the
      PTE_RDONLY bit in the resulting value overriding the DBM update and
      losing the dirty state.
      
      This patch fixes such race by setting PTE_RDONLY to the most permissive
      (lowest value) of the current entry and the new one.
      
      Fixes: 66dbd6e6 ("arm64: Implement ptep_set_access_flags() for hardware AF/DBM")

      The da9063/da9210 regulator quirk for R-Car Gen2 boards uses a bus
      notifier, and unregisters the notifier when it is no longer needed.
      However, a notifier must not be unregistered from within the call chain.

      take the semaphore during early boot. This is no longer the case as of
      upstream commit 1c3c5eab ("sched/core: Enable might_sleep() and
      smp_processor_id() checks early") and a deadlock occurs.

      powerpc/64: Fix __check_irq_replay missing decrementer interrupt · 3db40c31
      Nicholas Piggin authored
      If the decrementer wraps again and de-asserts the decrementer
      exception while hard-disabled, __check_irq_replay() has a test to
      notice the wrap when interrupts are re-enabled.
      
      The decrementer check must be done when clearing the PACA_IRQ_HARD_DIS
      flag, not when the PACA_IRQ_DEC flag is tested. Previously this worked
      because the decrementer interrupt was always the first one checked
      after clearing the hard disable flag, but HMI check was moved ahead of
      that, which introduced this bug.
      
      This can cause a missed decrementer interrupt if we soft-disable
      interrupts then take an HMI which is recorded in irq_happened, then
      hard-disable interrupts for > 4s to wrap the decrementer.

      This can be reproduced by booting L1 guest w/ 'noapic' grub parameter, which
      means that tells the kernel to not make use of any IOAPICs that may be present
      in the system.
      
      Actually external_intr variable in nested_vmx_vmexit() is the req_int_win
      variable passed from vcpu_enter_guest() which means that the L0's userspace
      requests an irq window. I observed the scenario (!kvm_cpu_has_interrupt(vcpu) &&
      L0's userspace reqeusts an irq window) is true, so there is no interrupt which
      L1 requires to inject to L2, we should not attempt to emualte "Acknowledge
      interrupt on exit" for the irq window requirement in this scenario.
      
      This patch fixes it by not attempt to emulate "Acknowledge interrupt on exit"
      if there is no L1 requirement to inject an interrupt to L2.

      [Added code comment to make it obvious that the behavior is not correct.
       We should do a userspace exit with open interrupt window instead of the
       nested VM exit.  This patch still improves the behavior, so it was
       accepted as a (temporary) workaround.]

      mmc: block: bypass the queue even if usage is present for hotplug · 7c84b8b4
      Shawn Lin authored
      The commit 304419d8 ("mmc: core: Allocate per-request data using the
      block layer core") refactored mechanism of queue handling caused
      mmc_init_request() can be called just after mmc_cleanup_queue() caused null
      pointer dereference.
      
      Another commit bbdc74dc ("mmc: block: Prevent new req entering queue
      after its cleanup") tried to fix the problem. However it actually miss one
      corner case.
      
      We could still reproduce the issue mentioned with these steps:
      (1) insert a SD card and mount it
      (2) hotplug it, so it will leave md->usage still be counted
      (3) reboot the system which will sync data and umount the card

      So mmc_blk_put wouldn't calling blk_cleanup_queue which actually the
      QUEUE_FLAG_DYING and QUEUE_FLAG_BYPASS should stay. Block core expect
      blk_queue_bypass_{start, end} internally to bypass/drain the queue before
      actually dying the queue, so it didn't expose API to set the queue bypass.
      I think we should set QUEUE_FLAG_BYPASS whenever queue is removed, although
      the md->usage is still counted, as no dispatch queue could be found then.
