This series contains updates for the Linux-kernel memory model: 1-3. Add SRCU support, courtesy of Alan Stern. 4. Update README for adding of SRCU support. 5. Update memory-barriers.txt on enforcing heavy ordering for port-I/O accesses, courtesy of Will Deacon. This one needs an ack, preferably by someone from Intel. Matthew Wilcox posted some feedback from an Intel manual here, which might be considered to be a close substitute, but... ;-) http://lkml.kernel.org/r/20181127192234.GF10377@bombadil.infradead.org 6. Update Documentation/explanation.txt to include SRCU support, courtesy of Alan Stern. 7. Dynamically check SRCU lock-to-unlock matching, courtesy of Luc Maranget. This needs an ack.
