File kdump-calibrate-initdata.patch of Package kdump

From: Petr Tesarik <ptesarik@suse.com>
Date: Thu Nov 5 11:51:49 2015 +0100
Subject: Add kernel initdata to boot requirements
References: bsc#953732
Patch-mainline: v.0.8.16
Git-commit: 96c35d6d53115684003f26c5415e82404e39a6dd

Kernel memory requirements at boot are greater than at run time.
The values are based on SLE12 (or SLE11 for architectures missing
in SLE12).
