All users of TASK_SIZE_OF(tsk) have migrated to mm->task_size or
TASK_SIZE_MAX since:
commit d696ca016d57 ("x86/fsgsbase/64: Use TASK_SIZE_MAX for
FSBASE/GSBASE upper limits"),
commit a06db751c321 ("pagemap: check permissions and capabilities at
open time"),

+#define TASK_SIZE            (current->thread.task_size)

I'm not sure I like he hidden 'current' argument to an
apparent constant.

Me neither.  But this patch is merely changing the implementation.
