Since the "ins.name" is not set while using raw instruction,
'perf annotate' with insn-stat gives wrong data:
Result from "./perf annotate --data-type --insn-stat":
Annotate Instruction stats
total 615, ok 419 (68.1%), bad 196 (31.9%)
Name : Good Bad
-----------------------------------------------------------
: 419 196
This patch sets "dl->ins.name" in arch specific function
"check_ppc_insn" while initialising "struct disasm_line".
Also update "ins_find" function to pass "struct disasm_line" as a
parameter so as to set its name field in arch specific call.
With the patch changes:
Annotate Instruction stats
total 609, ok 446 (73.2%), bad 163 (26.8%)
Name/opcode : Good Bad

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 reStructuredText 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.
