44b582b32a drm/amdgpu: Remove superfluous void * cast in debugfs_create_file() call
There is no need to cast a typed pointer to a void pointer when calling
a function that accepts the latter.  Remove it, as the cast prevents
further compiler checks.

Ras reboot debugfs node allows user one easy control to avoid
gpu recovery hang problem and directly reboot system per card
basis, after ras uncorrectable error happens. However, it is
one common entry, which should get rid of ras_ctrl node and
remove ip dependence when inputting by user. So add one new

v2: in commit mssage, add justification why ras reboot debugfs
node is needed.
v3: use debugfs_create_bool to create debugfs file for boolean value

06f7f57e87 drm/amdgpu: user pages array memory leak fix
user_pages array should always be freed after validation regardless if
user pages are changed after bo is created because with HMM change parse
bo always allocate user pages array to get user pages for userptr bo.

v2: remove unused local variable and amend commit

v3: add back get user pages in gem_userptr_ioctl, to detect application
bug where an userptr VMA is not ananymous memory and reject it.
