Overview

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

drm/amdgpu: change vm->task_info handling

This patch changes the handling and lifecycle of vm->task_info object. The major changes are:

vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted.
introducing two new helper funcs for task_info lifecycle management
- amdgpu_vm_get_task_info: reference counts up task_info before returning this info
- amdgpu_vm_put_task_info: reference counts down task_info
last put to task_info() frees task_info from the vm.

This patch also does logistical changes required for existing usage of vm->task_info.

V2: Do not block all the prints when task_info not found (Felix)

V3: Fixed review comments from Felix

Fix wrong indentation
No debug message for -ENOMEM
Add NULL check for task_info
Do not duplicate the debug messages (ti vs no ti)
Get first reference of task_info in vm_init(), put last in vm_fini()

V4: Fixed review comments from Felix

fix double reference increment in create_task_info
change amdgpu_vm_get_task_info_pasid
additional changes in amdgpu_gem.c while porting
