Subject: Re: [PATCH 1/2] boot: increase stack size for kernel boot loader decompressor

Hi Ingo,

I see you have applied the following patch to x86#for-akpm. It was
really ment for testing only. I think you ment to use this one instead?

[PATCH 1/2] boot: increase stack size for kernel boot loader decompressor
http://lkml.org/lkml/2008/3/25/497

Otherwise, please consider [PATCH] x86: cleanup boot-heap usage instead.
http://lkml.org/lkml/2008/4/8/90

Greetings,
	Alexander
