Peter Zijlstra 5180dff752 x86: Increase exception stack sizes ...

[ Upstream commit 7fae4c24a2 ]

It turns out that a single page of stack is trivial to overflow with
all the tracing gunk enabled. Raise the exception stacks to 2 pages,
which is still half the interrupt stacks, which are at 4 pages.
