binder: replace vmalloc range if need more memory [1/1]
PD#SWPL-5553
Problem:
Binder will allocate about 1MB vmalloc memory for IPC for each process,
but under code like GTVS, there are about over 100 vmalloc ranges
allocated by binder, which cause vmalloc address range not enough for
other modules.
Solution:
1, only vmalloc 4KB at first;
2, if user space need more memory, try to allocate a new vmalloc
range with large size and move all related data to new place
3, dump vmalloc info if vmalloc failed
Verify:
