has been removed from the -mm tree. Its filename was
i386-enable-4k-stacks-by-default.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: i386: enable 4k stacks by default
From: Adrian Bunk <bunk@xxxxxxxxx>
This patch enables 4k stacks by default.
4k stacks have become a well-tested feature used fore a long time in Fedora
and even in RHEL 4.
There are no known problems in in-kernel code with 4k stacks still present
after Neil's patch that went into -mm nearly two months ago.
Defaulting to 4k stacks in -mm kernel will give some more testing coverage
and should show whether there are really no problems left.
Keeping the option for now should make the people happy who want to use the
experimental -mm kernel but don't trust the well-tested 4k stacks.
Additionally, make it more obvious that available stack space is not being
halved.

If you say Y here the kernel will use a 4Kb stacksize for the
kernel stack attached to each process/thread. This facilitates
running more threads on a system and also reduces the pressure
on the VM subsystem for higher order allocations. This option
- will also use IRQ stacks to compensate for the reduced stackspace.
