Summary
drm/amdkfd: fix a vulnerability of integer overflow in kfd debugger
Details

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

drm/amdkfd: fix a vulnerability of integer overflow in kfd debugger

getqueueids() computes arraysize = numqueues * sizeof(uint32t), which could overflow on 32-bit sizet build. using arraysize() instead, it saturates to SIZEMAX on overflow.

(cherry picked from commit 2d57a0475f085c08b49312dfd8edcb461845f285)
