2015-07-13cxl: use more common format specifierRasmus Villemoes1-5/+5
A precision of 16 (%.16llx) has the same effect as a field width of 16 along with passing the 0 flag (%016llx), but the latter is much more common in the kernel tree. Update cxl to use that.

2015-01-22cxl: Add tracepointsIan Munsie1-0/+459
This patch adds tracepoints throughout the cxl driver, which can provide insight into: - Context lifetimes - Commands sent to the PSL and AFU and their completion status - Segment and page table misses and their resolution - PSL and AFU interrupts - slbia calls from the powerpc copro_fault code These tracepoints are mostly intended to aid in debugging (particularly for new AFU designs), and may be useful standalone or in conjunction with hardware traces collected by the PSL (read out via the trace interface in debugfs) and AFUs.
