This macro isn't used in Linux, now. Delete in include/linux/sched.h
and arch's include/asm. This would confuse people who are
implementing the COMPAT feature for architecture.

It would help to list how long it has been unused for. Looking through
the git history, I see commit a06db751c321 ("pagemap: check
permissions and capabilities at open time") removing the last user.
I would normally offer to take the entire series through the asm-generic
tree, as I do for this kind of cross-architecture work. I'll probably
not have time before the merge window to pick it up though, so it
may be better to go through the architecture trees, or possibly
linux-mm for anything that fails to get picked up.
For the series:

I think you should use test_thread_flag() instead.
Or even better: use is_32bit_task() and bring back this macro as a
single line, something like:
#define TASK_SIZE (is_32bit_task() ? TASK_SIZE_USER32 : TASK_SIZE_USER64)

Okay, looks better. I would fix it in the next version.

Note that is_32bit_task() exists on powerpc, parisc and sparc.
For other ones you can still use test_thread_flag() instead of
test_tsk_thread_flag(current)
