Problem:
The core-dump file cannot be saved to /data in Android.
Solution:
a. Fix BUG for bad page state when lazy_clear_work is running.
b. Print the parameter infor required for the crash tools.
c. Support for storing crashdump files in Android /data/vender/ramdump/
1) When a kernel panic occurs, flush cache all.
2) Restart to uboot stage and compress the full DDR.
3) Set kernel dts rsv mem based on compressed infor.
4) Crop reserved memory sub nodes to reduce mem usage.
5) Kernel stage parsing dts to configure rsv mem.
6) Android init.rc read sysnode, and generate crash file.
