kdump-0.8.7-bsp.patch

From: Petr Tesarik <ptesarik@suse.cz>
Subject: Add disable_cpu_apicid for BSP to the commandline
References: bnc#861981
Patch-mainline: v0.8.8
Since the BSP cannot be brought up in the kdump environment, and there is no
reliable way of getting the APIC ID of an offlined CPU, it must be figured
out by the primary kernel and passed as a command-line option.

From: Petr Tesarik <ptesarik@suse.cz>
Subject: Use nr_cpus instead of maxcpus with recent kernels.
References: FATE#315725
Patch-mainline: v0.8.8
Linux 2.6.34+ has nr_cpus, which limits the number of possible CPUs
(unlike maxcpus, which only limits the number of online CPUs at boot).
For compatibility, use maxcpus with older kernels.
