According to Alex, most APUs from that time seem to have the same issue
(vbios says 48Mhz, actual is 100Mhz). I only have a CHIP_STONEY so I
limit the fixup to CHIP_STONEY

The existing validations are incorrect and insufficient. This is
motivated by OOB access in amdgpu_vm_update_range when
offset_in_bo+map_size overflows.

Extend the address and size validations to AMDGPU_VA_OP_UNMAP and
AMDGPU_VA_OP_CLEAR by moving the validations to amdgpu_gem_va_ioctl.
Internal users of amdgpu_vm_bo_map are no longer validated but they
should be fine.
Userspace (radeonsi and radv) seems fine as well.

kgd_mem should be accessed with p->mutex locked, or it could have been

Set *q to NULL on errors, otherwise pqm_create_queue would free it
