PCI/MSI: Move code into a separate directory2021-12-09T10:52:22+00:00Thomas Gleixnertglx@linutronix.de2021-12-06T22:27:47+00:00urn:sha1:288c81ce4be7c15544605594966faaeb8803b5da
msi.c is getting larger and really could do with a splitup. Move it into
its own directory to prepare for that.

The guarantees provided by mmiowb() are now provided implicitly by
spin_unlock(), so remove all references to this most confusing of
barriers from our Documentation.
Good riddance.

Add a restructured text file describing how to write drivers with support
for P2P DMA transactions. The document describes how to use the APIs that
were added in the previous few commits.
Also adds an index for the PCI documentation tree even though this is the
only PCI document that has been converted to restructured text at this
time.

which will go in this directory.
