* refactor: kpm: memory management migrate to sukisu side
* fix: build warning in some gki2 device
fix stack frame size warning (maybe) in gki2 device, specialy in ShirkNeko's device
* chore: use pr_info instead of printk
* feat: check the validity of pointers sent from user space
Sometimes, ksud or other root processes might request a kpm ioctl,
but data incorrectly, such as invalid pointer,
which cause the kernel to crash.
If the request is made by ksud at boot time, the situation is even worse,
as it can cause the system to enter the boot loop.
Therefore, I believe we need to check pointer integrity in kernel space to fix this problem.
