Merge tag 'nfs-for-3.19-1' into nfsd for-3.19 branch

Mainly what I need is 860a0d9e51 "sunrpc: add some tracepoints in
svc_rqst handling functions", which subsequent server rpc patches from
jlayton depend on.  I'm merging this later tag on the assumption that's
more likely to be a tested and stable point.

A device node may contain either "interrupts" or "interrupts-extended", but not
both. If both properties are present, then the operating system should log an
error and use only the data in "interrupts".

Additionally to the properties specified in the above standards a host bridge
driver implementation may support the following properties:
- linux,pci-domain:
If present this property assigns a fixed PCI domain number to a host bridge,
otherwise an unstable (across boots) unique number will be assigned.
It is required to either not set this property at all or set it for all
host bridges in the system, otherwise potentially conflicting domain numbers
may be assigned to root buses behind different host bridges. The domain
number for each host bridge in the system must be unique.
