Pull x86 fixes from Thomas Gleixner:
"A small set of fixes for x86:
- Cure the fallout from the MSI irqdomain overhaul which missed that
the Intel IOMMU does not register virtual function devices and
therefore never reaches the point where the MSI interrupt domain is
assigned. This made the VF devices use the non-remapped MSI domain
which is trapped by the IOMMU/remap unit
- Remove an extra space in the SGI_UV architecture type procfs output
for UV5
- Remove a unused function which was missed when removing the UV BAU
TLB shootdown handler"
