I suspect this may be caused by the test assuming that stack growth is
downward, but I don't really understand the test well enough to be sure.
I'll disable this set of tests for m68k going forward, so I am not going
to report the problem again in the future.
On m68k, the stack does grow downward.
Sorry, I meant to say upward, but apparently I was wrong.
Maybe because m68k only has 2 byte alignment for 32 bit items.
That causes grief in many places.
Although kmalloc() returning a larger alignment would fix some
of them without using much more memory?
We're actually planning to switch the default alignment in Gentoo and Debian on m68k
to 32 bits since a lot of upstream projects such as OpenJDK, Qt, LLVM, Firebird and
Mold and many more expect 32-bit alignment.
