From: Sukadev Bhattiprolu
perf_mem_data_src is an union that is initialized via the ->val field
and accessed via the bitmap fields. For this to work on big endian
platforms, we also need a big-endian represenation of perf_mem_data_src.

perf_sample_data_init initialize the data source variable "->val"
with PERF_MEM_NA. New value should not be ORed since the userspace
perf tool will look at bitmap field when displaying the hierarchy levels.
