[PATCH v2 00/14] XIVE2 changes for TIMA operations

[Michael Kowal]

In XIVE Gen 2 there are many operations that were not modeled and are
needed for PowerVM.  These changes are associated with the following Thread
Interrupt Management Area subjects:
 - OS context
 - Thread context
 - Pulling contexts to 'cache lines'
 - Pool targets
 - Enhaced trace data for XIVE Gen2

version 2:
- use dma_memory_write() instead of cpu_physical_memory_write()
- use ternery operator in NVG/NVC pnv_xive2_vst_read/write()
- removed xive2_nvgc_set_backlog() until it is needed
- re-defined word 2 valid bits since it is the same in each Reporting
- provided better fix for possible NSR operation overflow
- moved changes for operations that can occur on ring, in a new patch set 
(10/13)
