Hello,
This is patchset to add new callchain related config options so that
users don't need to pass their preference to the cmdline everytime.
Following config options will be added, and users can set appropriate
values to ~/.perfconfig file. Note that the dump-size option is
meaningful only if record-mode = dwarf.
$ cat ~/.perfconfig
[call-graph]
record-mode = dwarf
dump-size = 4096
print-type = graph
order = callee
threshold = 0.5
print-limit = 128
sort-key = function
$ perf record -vg sleep 1
callchain: type DWARF
callchain: stack dump size 4096
mmap size 528384B
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.054 MB perf.data (~2378 samples) ]
Looking at the vmlinux_path (7 entries long)
Using /lib/modules/3.16.3-1-ARCH/build/vmlinux for symbols
You can also get this from 'perf/callchain-config-v1' branch on my tree

Any comments are welcomed, thanks
