Peter Anvin" , Andrew Morton , linux-kernel@vger.kernel.org Subject: [PATCH 1/2] boot: increase stack size for kernel boot loader decompressor Content-Disposition: inline; filename=compressed-head_64 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org * Increase stack size for the kernel bootloader decompressor. This is needed to boot a kernel with NR_CPUS = 4096. I tested with 8k stack size but that wasn't sufficient.
