Revert "KVM: Save/restore state of assigned PCI device"
From: Alex Williamson<[email protected]>
This reverts ed78661f2614d3c9f69c23e280db3bafdabdf5bb as it assumes
the saved PCI state will remain valid for the entire length of time
that it is attached to a guest. This fails when userspace makes use
of the pci-sysfs reset interface, which invalidates the saved device
state, leaving nothing to be restored after the device is reset on
de-assignment. This leaves the device in an unusable state.
3.0.0 will add an interface for KVM to save the PCI state in a
buffer unaffected by other callers of pci_reset_function(), but the
most appropriate stable fix seems to be reverting this change since
the original assumption about the device saved state persisting is
incorrect.
Thanks, queued for 2.6.39.
