Yup, SeongJae Park sent me the same report, and it just made it to
top-of-tree as commit 24be4d0b46bb ("arch/arm64/mm/fault: Fix
undeclared variable error in do_page_fault()")
This was actually an architecture I test myself, but I think UP ends
up turning off CONFIG_PER_VMA_LOCK.
I do wonder how much point there is to have a non-SMP build of
architectures like x86-64 and arm64 at all...
But I guess people still run them in qemu.
