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.

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.
