This error could happen when the GFP_HIGHUSER flag is set, such an error
can also be seen on the X86 platform. According to the kernel document in
gfp_types.h, "the GFP_HIGHUSER is for userspace allocations that may be
mapped to userspace, it do not need to be directly accessible by the
kernel."
However, drm/etnaviv will use the pages to implement vmap and mmap
operations of the GEM object function. The flag still set at present.
When we can't get pages, it certainly is a bug. Hence, we should print
this kind of error with drm_err() instead of dev_dbg().
