Summary
drm/amdkfd: Destroy KFD debugfs after destroy KFD wq
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: Destroy KFD debugfs after destroy KFD wq

Since KFD proc content was moved to kernel debugfs, we can't destroy KFD debugfs before kfdprocessdestroywq. Move kfdprocessdestroywq prior to kfddebugfsfini to fix a kernel NULL pointer problem. It happens when /sys/kernel/debug/kfd was already destroyed in kfddebugfsfini but kfdprocessdestroywq calls kfddebugfsremoveprocess. This line debugfsremoverecursive(entry->proc_dentry); tries to remove /sys/kernel/debug/kfd/proc/<pid> while /sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel NULL pointer.

(cherry picked from commit 0333052d90683d88531558dcfdbf2525cc37c233)
