KGTP (Linux Kernel debugger and tracer) 20120424 release(doc update)[0/3]

[Hui Zhu <teawater@gmail.com>]

KGTP is a realtime and lightweight Linux Kernel debugger and tracer.
It makes Linux Kernel supply a GDB remote debug interface. Then GDB in current machine or remote machine can debug and trace Linux through GDB tracepoint and some other functions without stopping the Linux Kernel.
And even if the board doesn't have GDB on it and doesn't have interface for remote debug. It can debug the Linux Kernel using offline debug (See http://code.google.com/p/kgtp/wiki/HOWTO#/sys/kernel/debug/gtpframe_and_offline_debug).
And it can work with Android (See http://code.google.com/p/kgtp/wiki/HowToUseKGTPinAndroid).
Now, it supports X86-32, X86-64, MIPS and ARM.
