Inspired by commit d57d6fe5bf34 ("drivers: hv: log when enabling crash_kexec_post_notifiers"),
a good idea is to signal on dmesg about unconditionally enabling the kernel
parameter crash_kexec_post_notifiers, which affects how kdump works.
By checking the source code, found 2 more cases besides Hyper-V, so let's
print that on dmesg for them as well.
