Ravi Bangoria 863b61caae perf annotate: Do not truncate instruction names at 6 chars
[ Upstream commit 05d0e62d9f ]

There are many instructions, esp on PowerPC, whose mnemonics are longer
than 6 characters. Using precision limit causes truncation of such
mnemonics.

Fix this by removing precision limit. Note that, 'width' is still 6, so
alignment won't get affected for length <= 6.

Before:

   li     r11,-1
   xscvdp vs1,vs1
   add.   r10,r10,r11

After:

  li     r11,-1
  xscvdpsxds vs1,vs1
  add.   r10,r10,r11

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
