While looking into something different I noticed that there are a couple of
Kconfig options which were only selected by IA-64 and which are now unused.

So remove them and simplify the code a bit.

Heiko Carstens (3):
  arch: remove ARCH_THREAD_STACK_ALLOCATOR
  arch: remove ARCH_TASK_STRUCT_ALLOCATOR
  arch: remove ARCH_TASK_STRUCT_ON_STACK
