CP-4109: Netback debugfs patch
CA-140333: fix use of xen-pciback.hide kernel option

Improve test for whether to add a "reset" sysfs file.  It would
previously get it wrong if probe() was called before all the sysfs
files were created (pci sysfs file were being created during a
late_initcall()).
CP-4109: Fix filename
CA-140556: Fix possible memory access problem in events_fifo.c

sync_test_bit function require a long* read access to pointer.
This is a problem if the you are using last entry in the page causing
an access to next page. If this page is not readable you get a memory
access failure (page fault).
CP-8891: Port ioctl to restrict evtchn

This is quite a straightforward port.
No ioctl was added so no additional checks to do.
Events get added to tree only for the restricted domain so is
not possible to deal with other events from Xen.

CP-8890: Implement ioctl to restrict privcmd

Solution base on old implementation but does not require changes to
userspace beside restricting the handle (no changes to other hypercalls).
