      PCI(E)GART isn't quite stable it seems, fall back to old method until I get
the time to sort it out properly.

      x86/amd-iommu: Use only per-device dma_ops · 27c2127a
      Joerg Roedel authored 
      Unfortunatly there are systems where the AMD IOMMU does not
cover all devices. This breaks with the current driver as it
initializes the global dma_ops variable. This patch limits
the AMD IOMMU to the devices listed in the IVRS table fixing
DMA for devices not covered by the IOMMU.

      x86/amd-iommu: Fix 3 possible endless loops · 0de66d5b
      Joerg Roedel authored 
      The driver contains several loops counting on an u16 value
where the exit-condition is checked against variables that
can have values up to 0xffff. In this case the loops will
never exit. This patch fixed 3 such loops.

      [S390] use generic RCU page-table freeing code · 36409f63
      Martin Schwidefsky authored 
      Replace the s390 specific rcu page-table freeing code with the
generic variant. This requires to duplicate the definition for the
struct mmu_table_batch as s390 does not use the generic tlb flush
code.

While we are at it remove the restriction that page table fragments
can not be reused after a single fragment has been freed with rcu
and split out allocation and freeing of page tables with pgstes.

      [S390] qdio: Split SBAL entry flags · 3ec90878
      Jan Glauber authored 
      The qdio SBAL entry flag is made-up of four different values that are
independent of one another. Some of the bits are reserved by the
hardware and should not be changed by qdio. Currently all four values
are overwritten since the SBAL entry flag is defined as an u32.

Split the SBAL entry flag into four u8's as defined by the hardware
and don't touch the reserved bits.

      Currently KVM masks out the known good facilities only for the first
double word, but passed the 2nd double word without filtering. This
breaks some code on newer systems:

      [S390] kvm-s390: Fix host crash on misbehaving guests · a578b37c
      Christian Borntraeger authored 
      commit 9ff4cfb3 ([S390] kvm-390: Let
kernel exit SIE instruction on work) fixed a problem of commit
commit cd3b70f5 ([S390] virtualization
aware cpu measurement) but uncovered another one.

If a kvm guest accesses guest real memory that doesnt exist, the
page fault handler calls the sie hook, which then rewrites
the return psw from sie_inst to either sie_exit or sie_reenter.
On return, the page fault handler will then detect the wrong access
as a kernel fault causing a kernel oops in sie_reenter or sie_exit.

We have to add these two addresses to the exception  table to allow
graceful exits.
