When CONFIG_ARCH_TASK_STRUCT_ON_STACK=y (i.e. ARCH=ia64), task_struct and the thread stack are shared.
The ifdef condition of CONFIG_ARCH_TASK_STRUCT_ON_STACK is opposite.
Now that the init thread stack is constructed by the linker script, this is not a practical problem, but let's fix the code just in case.
Fixes: 0500871f21b2 ("Construct init thread stack in the linker script rather than by union") Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> ---
