Hello,
I also haven't seen this format in other kernel code, but, in cma, they use
this format as following.
function(arg1, arg2, ...): some message
If we all dislike this format, we can change it after merging this
patchset. Until then, it seems better to me to leave it as is.

This pr_debug() comes from ppc kvm's kvm_cma_init_reserved_areas().
I want to maintain all log messages as much as possible to reduce confusion
with this generalization.
Thanks.
