Merge tag 'driver-core-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core merge from Greg Kroah-Hartman:
 "Here is the big driver core update for 3.7-rc1.

  A number of firmware_class.c updates (as you saw a month or so ago),
  and some hyper-v updates and some printk fixes as well.  All patches
  that are outside of the drivers/base area have been acked by the
  respective maintainers, and have all been in the linux-next tree for a
  while.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

+
+<test> 用于表示要测量的目标
+请先确保您已经有正确的System.map / vmlinux配置！
+
+对于linux系统来说，配置vmlinuz最容易的方法可能就是使用“make install”，然后修改
+/sbin/installkernel将vmlinux拷贝到/boot目录，而System.map通常是默认安装好的
+
+Readprofile
+-----------
+2.6系列内核需要版本相对较新的readprofile，比如util-linux 2.12a中包含的，可以从:
+
+http://www.kernel.org/pub/linux/utils/util-linux/ 下载
+
+大部分linux发行版已经包含了.
+
+启用readprofile需要在kernel启动命令行增加”profile=2“
+
+clear		readprofile -r
+		<test>
+dump output	readprofile -m /boot/System.map > captured_profile
+
+Oprofile
+--------
+
+从http://oprofile.sourceforge.net/获取源代码（请参考Changes以获取匹配的版本）
+在kernel启动命令行增加“idle=poll”
+
+配置CONFIG_PROFILING=y和CONFIG_OPROFILE=y然后重启进入新kernel
+
+./configure --with-kernel-support
+make install
+
+想得到好的测量结果，请确保启用了本地APIC特性。如果opreport显示有0Hz CPU，
+说明APIC特性没有开启。另外注意idle=poll选项可能有损性能。
+
+One time setup:
+		opcontrol --setup --vmlinux=/boot/vmlinux
+
+clear		opcontrol --reset
+start		opcontrol --start
+		<test>
+stop		opcontrol --stop
+dump output	opreport >  output_file
+
+如果只看kernel相关的报告结果，请运行命令 opreport -l /boot/vmlinux > output_file
+
+通过reset选项可以清理过期统计数据，相当于重启的效果。
