      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"

        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.

        of devices using runtime PM during system-wide suspend, improve the
        intel_pstate driver documentation and clean up the cpufreq core.
      
        Specifics:
      
         - Make the recently added Tegra194 cpufreq driver use
           read_cpuid_mpir() instead of cpu_logical_map() to avoid exporting
           logical_cpu_map (Sumit Gupta).
      
         - Drop the automatic system wakeup event reporting for devices with
           pending runtime-resume requests during system-wide suspend to avoid
           spurious aborts of the suspend flow (Rafael Wysocki).
      
         - Fix build warning in the intel_pstate driver documentation and
           improve the wording in there (Randy Dunlap).
      
         - Clean up two pieces of code in the cpufreq core (Viresh Kumar)"

       - Fix kernel build with the integrated LLVM assembler which doesn't see
         the -Wa,-march option.
      
       - Fix "make vdso_install" when COMPAT_VDSO is disabled.
      
       - Make KVM more robust if the AT S1E1R instruction triggers an
         exception (architecture corner cases).

      kernel.h: Silence sparse warning in lower_32_bits · ef91bb19
      Herbert Xu authored
      I keep getting sparse warnings in crypto such as:
      
        CHECK   drivers/crypto/ccree/cc_hash.c
         drivers/crypto/ccree/cc_hash.c:49:9: warning: cast truncates bits from constant value (47b5481dbefa4fa4 becomes befa4fa4)
         drivers/crypto/ccree/cc_hash.c:49:26: warning: cast truncates bits from constant value (db0c2e0d64f98fa7 becomes 64f98fa7)
         [.. many more ..]
      
      This patch removes the warning by adding a mask to keep sparse
      happy.
