Sadly, I can confirm: weston swelling to double size = on qemuarm64 is caused by this recent change in glibc:

=
+EXTRA_OECONF_append_aarch64 =3D " --enable-memory-tagging"<= /div>

You can verify with this innocent looking program.= Run 'free' while it is running and compare with and without taggin= g:

main()
{
=C2=A0 =C2=A0for (int i=3D0; i&l= t;768; i++)
=C2=A0 =C2=A0 =C2=A0 =C2=A0calloc(1,262368);
=C2=A0 =C2= =A0sleep(200);
}

I'll queue a revert.

It seems that mesa, for some reason, allocates a lot m= ore RAM in qemuarm64 (150 Mb more or so), than it does in qemux86_64. I'= ;ll investigate.
