Add a new sort option "data_page_size" for --mem-mode sort. With this
option applied, perf can sort and report by sample's data page size.
Here is an example:
perf report --stdio --mem-mode
--sort=comm,symbol,phys_daddr,data_page_size
# To display the perf.data header info, please use
# --header/--header-only options.
#
#
# Total Lost Samples: 0
#
# Samples: 9K of event 'mem-loads:uP'
# Total weight : 9028
# Sort order : comm,symbol,phys_daddr,data_page_size
#
# Overhead Command Symbol Data Physical
# Address
# Data Page Size
