File makedumpfile-ppc64-VA-range-SUSE.patch of Package makedumpfile

From: Petr Tesarik <ptesarik@suse.cz>
Subject: Use correct l3 index size with SLE15-SP1 ppc64le kernels
References: bsc#1123015
Upstream: never, SUSE-specific

SLE 15 SP1 backported commit c2b4d8b7417a ("powerpc/mm/hash64: Increase
the VA range"), to Linux 4.12, so let's check SUSE_PRODUCT_CODE.
