Yes, that sounds right. I installed the attached patch into Emacs master 
on Savannah, and am boldly closing the bug as fixed. We can reopen it if 
I'm wrong.

Thanks, Rahguzar, for reporting the bug.

Dear Emacs Maintainers,

I am using GNU/Linux on an Apple M2 processor using the Asahi Linux
project [1]. They provide a kernel with 16KB page size [2]. This causes proced
to show incorrect values for percentage memory (other memory related
attributes might also be affected). E.g. comparing with top I see that
value reported by proced is a quarter of that related by top.
