x86: Check stack overflow in detail
Currently, only kernel stack is checked for the overflow, which
is not sufficient for systems that need a high reliability. To
enhance it, it is required to check the IRQ and exception
stacks, as well.
This patch checks all the stack types and will cause messages of
stacks in detail when free stack space drops below a certain
limit except user stack.
