The patch titled
x86_64: configure stack size
has been removed from the -mm tree. Its filename was
x86_64-configure-stack-size.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: x86_64: configure stack size
From: Christoph Lameter <clameter@xxxxxxx>
Make the stack size configurable necessary. SGI NUMA configurations may need
more stack because cpumasks and nodemasks are at times kept on the stack.
This patch allows to run with 16k or 32k kernel stacks.
