[RFC PATCH] x86_64: double the x86_64 kernel stack size?

[Zhouyi Zhou]

Somethings I compiled the Linux network modules (especially bridge and netfilter)
without optimization, the kernel always crashes because of exhausted kernel stack.

The similar problem has been discussed in
http://lists.linuxfoundation.org/pipermail/bridge/2005-January/004402.html

Is it OK the double the x86_64 kernel stack size?
