The only difference is the free_thread_info function, which frees
xstate.
Use the new arch_release_task_struct() function instead and switch
over to the core allocator.

These days 4 kilobytes of stack just aren't enough for reliably operation,
and people using lots of threads have long switched to 64-bit kernels, so
remove the CONFIG_4KSTACKS option.

Impact: simplification
We only need to map the kernel in head_32.S, not the whole of
lowmem. We use 512MB as a reasonable (but arbitrary) limit on
the maximum size of the kernel image.

pgtable*.h is intended for definitions relating to actual pagetables
and their entries, so move all the definitions for
(pte|pmd|pud|pgd)(val)?_t to the appropriate pgtable*.h headers.
