Problem:
If enabled 32bit kasan on T5W with VMAP, kernel can not boot.
This case can not happen on T5D.
Solution:
Rootcause is bss cleared but real data keeps in cache, not flushed
into DDR, and physical kasan shadow page soon be mapped to shadow
memory while in shadow virtual address we see random data, which
caused kasan check failed in vmap fixup function and crashed. So
just add a dcache flush function call after bss cleared.

2. The kernel path and kernel version can be obtained through calculation,
so there is no need to add additional parameters
3. Optimize the maximum number of patches to improve performance
4. Optimize lunch patch
5. Optimize debug logs
