Alex Deucher 009c4d78bc drm/amdkfd: don't allow mapping the MMIO HDP page with large pages 
commit be4a2a81b6b90d1a47eaeaace4cc8e2cb57b96c7 upstream.

We don't get the right offset in that case.  The GPU has
an unused 4K area of the register BAR space into which you can
remap registers.  We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM.  However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.
