This sets CONFIG_KASAN_SHADOW_OFFSET for _all_ X86 configurations, doesn't it?

-config KASAN_SHADOW_OFFSET - hex - default 0xdffffc0000000000 if X86_64
While here it used to depend, at least, on HAVE_ARCH_KASAN. But grepping the tree shows the two places where CONFIG_KASAN_SHADOW_OFFSET is currently used are guarded by #ifdef CONFIG_KASAN. So perhaps the default line should actually read default 0xdffffc0000000000 if KASAN after the move. Would that work? Paul Bolle
