	The Documentation/ folder no longer exists. Either everything important can be found in the man pages or other documentation files. Fix the mentioning of Documentation/. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-04-11	docs: move some of them to the root directory	Daniel Borkmann	1	-0/+833
	Lets move CodingStyle, SubmittingPatches, and Sponsors into the root directory of netsniff-ng and remove the Documentation folder. Some of those files are quite bloated, and most of these things should be in the man-pages anyway. They should be the only big sources of documentation, nothing else. The rest is currently put here: http://pub.netsniff-ng.org/docs/ Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

irqdomain: Avoid activating interrupts more than once

Since commit f3b0946d629c ("genirq/msi: Make sure PCI MSIs are activated early"), we can end-up activating a PCI/MSI twice (once at allocation time, and once at startup time). This is normally of no consequences, except that there is some HW out there that may misbehave if activate is used more than once (the GICv3 ITS, for example, uses the activate callback to issue the MAPVI command, and the architecture spec says that "If there is an existing mapping for the EventID-DeviceID combination, behavior is UNPREDICTABLE"). While this could be worked around in each individual driver, it may make more sense to tackle the issue at the core level. In order to avoid getting in that situation, let's have a per-interrupt flag to remember if we have already activated that interrupt or not.
