Thanks!

As the commit message says, Rust modules still fail to load with a
larger mem=, because Rust code uses the small code model. Zigit Zo
posted a fix for this in 2024 [1]. It is the same change as the one I
would send:

	KBUILD_RUSTFLAGS += -Ccode-model=large

It was not merged. Was it because the patch has no Signed-off-by?
