Recently the loongarch defconfig stopped working with the default 128 MiB
of memory. The VM just spins infinitively.
Increasing the available memory to 1 GiB, similar to s390, fixes the
issue. To avoid having to do this for each architecture on its own,
proactively apply to all architectures.

Did we take care of this one? Apologies if I didn't. We can include
this in 6.14 pr.
