[PATCH v16 12/21] powerpc: Use sizeof(struct thread_info) in INIT_SP_LIMIT
From: Michael Ellerman <mpe@ellerman.id.au>

Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
From: Christophe Leroy <redacted> Currently INIT_SP_LIMIT uses sizeof(init_thread_info), but that symbol won't exist when we enable THREAD_INFO_IN_TASK. So just use the sizeof the type which is the same value but will continue to work.
