Please, ignore this patch.

We will need more changes before being able to merge this code. In
particular, create_stack from sched.c should stop using uk_palloc since
it is expecting a pointer aligned at STACK_SIZE (c.f. uk_thread_current
from thread.h).

This can be done by using uk_posix_memalign in create_stack, but before
that uk_posix_memalign_ifpages should be fixed to support
align > __PAGE_SIZE.

I will submit a patch series soon.
