      Pull x86 fixes from Thomas Gleixner:
       "Three interrupt related fixes for X86:
      
         - Move disabling of the local APIC after invoking fixup_irqs() to
           ensure that interrupts which are incoming are noted in the IRR and
           not ignored.
      
         - Unbreak affinity setting.
      
           The rework of the entry code reused the regular exception entry
           code for device interrupts. The vector number is pushed into the
           errorcode slot on the stack which is then lifted into an argument
           and set to -1 because that's regs->orig_ax which is used in quite
           some places to check whether the entry came from a syscall.
      
           But it was overlooked that orig_ax is used in the affinity cleanup
           code to validate whether the interrupt has arrived on the new
           target. It turned out that this vector check is pointless because
           interrupts are never moved from one vector to another on the same
           CPU. That check is a historical leftover from the time where x86
           supported multi-CPU affinities, but not longer needed with the now
           strict single CPU affinity. Famous last words ...
      
         - Add a missing check for an empty cpumask into the matrix allocator.
      
           The affinity change added a warning to catch the case where an
           interrupt is moved on the same CPU to a different vector. This
           triggers because a condition with an empty cpumask returns an
           assignment from the allocator as the allocator uses for_each_cpu()
           without checking the cpumask for being empty. The historical
           inconsistent for_each_cpu() behaviour of ignoring the cpumask and
           unconditionally claiming that CPU0 is in the mask struck again.
           Sigh.
      
        plus a new entry into the MAINTAINER file for the HPE/UV platform"

        the usb gadget patch now does not break some systems, and actually
        does what it was intended to do. Many thanks to Marek Szyprowski for

        Additionally, some more new USB quirks have been added to get some new
        devices to work properly based on user reports.
      
        Other than that, the patches are all here, and they contain:
      
         - usb gadget driver fixes
      
         - xhci driver fixes

      genirq/matrix: Deal with the sillyness of for_each_cpu() on UP · 784a0830
      Thomas Gleixner authored
      Most of the CPU mask operations behave the same way, but for_each_cpu() and
      it's variants ignore the cpumask argument and claim that CPU0 is always in
      the mask. This is historical, inconsistent and annoying behaviour.
      
      The matrix allocator uses for_each_cpu() and can be called on UP with an
      empty cpumask. The calling code does not expect that this succeeds but
      until commit e027ffff ("x86/irq: Unbreak interrupt affinity setting")
      this went unnoticed. That commit added a WARN_ON() to catch cases which
      move an interrupt from one vector to another on the same CPU. The warning
      triggers on UP.
      
      Add a check for the cpumask being empty to prevent this.

      KVM: arm64: Set HCR_EL2.PTW to prevent AT taking synchronous exception · 71a7f8cb
      James Morse authored
      AT instructions do a translation table walk and return the result, or
      the fault in PAR_EL1. KVM uses these to find the IPA when the value is
      not provided by the CPU in HPFAR_EL1.
      
      If a translation table walk causes an external abort it is taken as an
      exception, even if it was due to an AT instruction. (DDI0487F.a's D5.2.11
      "Synchronous faults generated by address translation instructions")
      
      While we previously made KVM resilient to exceptions taken due to AT
      instructions, the device access causes mismatched attributes, and may
      occur speculatively. Prevent this, by forbidding a walk through memory
      described as device at stage2. Now such AT instructions will report a
      stage2 fault.
      
      Such a fault will cause KVM to restart the guest. If the AT instructions
      always walk the page tables, but guest execution uses the translation cached
      in the TLB, the guest can't make forward progress until the TLB entry is
      evicted. This isn't a problem, as since commit 5dcd0fdb ("KVM: arm64:
      Defer guest entry when an asynchronous exception is pending"), KVM will
      return to the host to process IRQs allowing the rest of the system to keep
      running.

      KVM: arm64: Survive synchronous exceptions caused by AT instructions · 88a84ccc
      James Morse authored
      KVM doesn't expect any synchronous exceptions when executing, any such
      exception leads to a panic(). AT instructions access the guest page
      tables, and can cause a synchronous external abort to be taken.
      
      The arm-arm is unclear on what should happen if the guest has configured
      the hardware update of the access-flag, and a memory type in TCR_EL1 that
      does not support atomic operations. B2.2.6 "Possible implementation
      restrictions on using atomic instructions" from DDI0487F.a lists
      synchronous external abort as a possible behaviour of atomic instructions
      that target memory that isn't writeback cacheable, but the page table
      walker may behave differently.
      
      Make KVM robust to synchronous exceptions caused by AT instructions.
      Add a get_user() style helper for AT instructions that returns -EFAULT
      if an exception was generated.
      
      While KVM's version of the exception table mixes synchronous and
      asynchronous exceptions, only one of these can occur at each location.
      
      Re-enter the guest when the AT instructions take an exception on the
      assumption the guest will take the same exception. This isn't guaranteed
      to make forward progress, as the AT instructions may always walk the page
      tables, but guest execution may use the translation cached in the TLB.
      
      This isn't a problem, as since commit 5dcd0fdb ("KVM: arm64: Defer guest
      entry when an asynchronous exception is pending"), KVM will return to the
      host to process IRQs allowing the rest of the system to keep running.

      KVM: arm64: Add kvm_extable for vaxorcism code · e9ee186b
      James Morse authored
      KVM has a one instruction window where it will allow an SError exception
      to be consumed by the hypervisor without treating it as a hypervisor bug.
      This is used to consume asynchronous external abort that were caused by
      the guest.
      
      As we are about to add another location that survives unexpected exceptions,
      generalise this code to make it behave like the host's extable.
      
      KVM's version has to be mapped to EL2 to be accessible on nVHE systems.
      
      The SError vaxorcism code is a one instruction window, so has two entries
      in the extable. Because the KVM code is copied for VHE and nVHE, we end up
      with four entries, half of which correspond with code that isn't mapped.
