With sanitizers enabled, it becomes possible to overflow the stack when only a single page is used. Follow arm64's example and use the default kernel stack size instead. This is a bit wasteful, but without a guard page, overflow merely corrupts adjacent .bss entries and is thus difficult to debug. Note, with a GENERIC kernel we already consume over half of the available boot stack space, see the review for an example.
