Name: core_kernel_init.patch
Author: Ashok Raj (Intel Corporation)
D: This patch changes __init to __devinit to init_idle so that when a new
cpu
D: arrives, it can call these functions at a later time.

Re: [RFC IA64 Hotplug] [Patch 1/7] core_kernel_init.patch

[Andrew Morton]

These patches were disastrously wordwrapped by your mailer (usually an
indication that the code is using too-long lines, too).

Having nothing better to do, I fixed them all up and applied them to my
tree, thanks.

One of the patches adds a KDB initialisation hook to init/main.c.  Was this
deliberate?

Nope. The kdb was inadvertently included by mistake.. sorry about that.

I forgot one step in using the LOOKOUT to get the word wrap thingy to fix..
I will be careful the next time :-(
