It seems to be the most used argument for -c option so far. In the
beginning when you want to have the overall process report, so it makes
sense to make it the default one.Signed-off-by: Jiri Olsa

Adding "Total records" column into cacheline pareto table, between
cycles and cpu info.$ perf c2c report
...--- ---------- cycles ---------- Total cpu

It's useful to see how many recorded samples represent each offset.

Adding support for cascading options added by Namhyung in:
commit 369a2478973a ("tools lib subcmd: Support cascading options")
This way the report and record command share options with with c2c
command and can save some option duplicates. For now it's the 'v'
option.Signed-off-by: Jiri Olsa

Currently we display the cacheline list sorted on remote HITMs by
default.The problem is that they might not be always counted and 'perf c2c
report' displays an empty output. Thus it's more convenient to display
and sort the cacheline list based on the total of HITMs and have the
best change to see data in the default report run.Signed-off-by: Jiri Olsa

Set resort/display fields for both cachelines and single cacheline
displays.Cachelines are sorted on:
rmt_hitm
will be made configurable in following patches.
Following fields are display for cachelines:
dcacheline
tot_recs
percent_hitm
tot_hitm,lcl_hitm,rmt_hitm
stores,stores_l1hit,stores_l1miss
dram_lcl,dram_rmt
ld_llcmiss
tot_loads
ld_fbhit,ld_l1hit,ld_l2hit
ld_lclhit,ld_rmthitThe single cacheline is sort by:
offset,rmt_hitm,lcl_hitm
will be made configurable in following patches.
Following fields are display for each cacheline:
percent_rmt_hitm
percent_lcl_hitm
percent_stores_l1hit
percent_stores_l1miss
offset
pid
tid
mean_rmt
mean_lcl
mean_load

It is to be displayed in the single cacheline output:
node
It displays nodes hits related to cacheline accesses.
The node filed comes in 3 flavors:
- node IDs separated by ','
- node IDs with stats for each ID, in following format:
Node{cpus %hitms %stores}
- node IDs with list of affected CPUs in following format:
Node{cpu list}User can switch the flavor with -N option (-NN,-NNN).
It will be available in TUI to switch this with 'n' key.Signed-off-by: Jiri Olsa
