Problem:
Coverity failures
Solution:
1. Mark coverity event_tag: returned_null and
use_after_free as false positive.
2. Coverity supposes krealloc() will free tmp_buf and return
tmp_buf as tmp_buf2. This is incorrect, since tmp_buf is
freed only when returned value(tmp_buf2) is NOT the same as
tmp_buf in krealloc()

Problem:
TEXTOFFSET was changed from 0x00208000 to 0x02008000, causing some
devices to fail to start.
1. t5d Android U upgrade project, ko becomes build, uImage size
increases to 36MB. It is too big to relocate.
2. There is only 48MB in 0x020080000~0x5000000 area, and cannot
open kasan.
Solution:
1. use new config CONFIG_AMLOGIC_RAMDUMP_TEXTOFFSET instead of
CONFIG_AMLOGIC_RAMDUMP. And TEXTOFFSET is 0x00208000 default.
2. Use a new solution instead of modifying TEXT. Specifically,
during kernel panic, move 0-24MB to a higher address. Reboot to
uboot and then copy back.

Problem:
container_of thermal_governor_list head is not thermal_governor structure,
then we can't use gov->name to visit.
Solution:
use sprint_symbol to convert gov->name, and then use the converted symbol
to compare with the target governor name.if match then set the target
governor ,else skip current node.
note:
1.this solution strictly rely on CONFIG_KALLSYMS, if CONFIG_KALLSYMS
is not set for gki20 project, then the solution would fail.
2.remember to configure default governor in config file for non-gki20
project.
