linux-threadripper is available AUR

Contains bus reset fixes for PCIe passthrough on the AMD Threadripper platform.

Caused by (virt-manager):

Error starting domain: internal error: Unknown PCI header type '127'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 125, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 82, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1508, in startup
    self._backend.create()
  File "/usr/lib/python2.7/site-packages/libvirt.py", line 1069, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error: Unknown PCI header type '127'

It is now possible to start and stop VMs with PCIe passthrough without having to restart the Host.
