xhci: Use GFP_NOIO during device reset.
commit a6d940dd759bf240d28624198660ed34582a327b upstream.
When xhci_discover_or_reset_device() is called after a host controller
power loss, the virtual device may need to be reallocated. Make sure
xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing
the kernel to flush pending I/O while reallocating memory for a virtual
device for a USB mass storage device that's holding the backing store for
dirty memory buffers.
This patch should be queued for the 2.6.37 stable tree.
