Make process_attr() respect -F-ip, noting also that the condition in
process_attr() (callchain_param.record_mode != CALLCHAIN_NONE) is always
true so test the sample type directly.
Example:
Before:
$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.033 MB perf.data ]
$ perf script --call-trace | head -5
uname 30992 [006] 41758.313696574: cbr: 42 freq: 4219 MHz (156%) 0 [unknown] ([unknown] )
uname 30992 [006] 41758.313696907: _start 7f71792c4100 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-2.31.so )
uname 30992 [006] 41758.313699574: _dl_start 7f71792c4103 _start+0x3 (/usr/lib/x86_64-linux-gnu/ld-2.31.so )
uname 30992 [006] 41758.313699907: _dl_start 7f71792c4e18 _dl_start+0x28 (/usr/lib/x86_64-linux-gnu/ld-2.31.so )
uname 30992 [006] 41758.313701574: _dl_start 7f71792c5128 _dl_start+0x338 (/usr/lib/x86_64-linux-gnu/ld-2.31.so )
After:
$ perf script --call-trace | head -5
uname 30992 [006] 41758.313696574: cbr: 42 freq: 4219 MHz (156%)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
