30316047d6 refactor: kpm: memory management migrate to sukisu side (#539) 
* 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.

e41fa8ef62 Revert renaming symbols in KernelSU driver 
- In order to reduce the extra patch code and increase the rate of hunk succeed, we do not rename the symbols in KernelSU drvier but instead do it all in kernel/kallsym.c

- Make susfs_starts_with() global as it maybe useful in future

ba71b410db kernel: kpm: add compatibility for kernel 4.14 and lower (#76) 
`thread_pid` is not defined in kernel 4.14 and lower, leading to compilation issue.
To fix this, use `pids[PIDTYPE_PID].pid` for kernel versions 4.14 and lower.
Else use `thread_pid` for kernel versions 4.19 and higher.
