      x86_64, asm: Work around AMD SYSRET SS descriptor attribute issue · 61f01dd9
      Andy Lutomirski authored
      AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with
      SS == 0 results in an invalid usermode state in which SS is apparently
      equal to __USER_DS but causes #SS if used.
      
      Work around the issue by setting SS to __KERNEL_DS __switch_to, thus
      ensuring that SYSRET never happens with SS set to NULL.
      
      This was exposed by a recent vDSO cleanup.
      
      Fixes: e7d6eefa x86/vdso32/syscall.S: Do not load __USER32_DS to %ss

      Pull intel iommu updates from David Woodhouse:
       "This lays a little of the groundwork for upcoming Shared Virtual
        Memory support — fixing some bogus #defines for capability bits and
        adding the new ones, and starting to use the new wider page tables
        where we can, in anticipation of actually filling in the new fields
        therein.
      
        It also allows graphics devices to be assigned to VM guests again.
        This got broken in 3.17 by disallowing assignment of RMRR-afflicted
        devices.  Like USB, we do understand why there's an RMRR for graphics
        devices — and unlike USB, it's actually sane.  So we can make an
        exception for graphics devices, just as we do USB controllers.
      
        Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to
        persistent requests.  X2APIC_OPT_OUT was added to the spec as a nasty
        hack to allow broken BIOSes to forbid us from using X2APIC when they
        do stupid and invasive things and would break if we did.
      
        Someone noticed that since Windows doesn't have full IOMMU support for
        DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid
        initialising the IOMMU on the graphics unit altogether.
      
        This means that it would be available for use in "driver mode", where
        the IOMMU registers are made available through a BAR of the graphics
        device and the graphics driver can do SVM all for itself.
      
        So they started setting the X2APIC_OPT_OUT bit on *all* platforms with
        SVM capabilities.  And even the platforms which *might*, if the
        planets had been aligned correctly, possibly have had SVM capability
        but which in practice actually don't"
