File kdump-recover-from-missing-CRASHTIME.patch of Package kdump

From: Petr Tesarik <ptesarik@suse.com>
Subject: Recover from missing CRASHTIME= in VMCOREINFO
References: bsc#1112387
Upstream: merged
Git-commit: 0bc94943a1df4d923aa20b9bd1ff01ed2e49d70c

CRASHTIME= may be missing in Xen Dom0 dumps.
Vmcoreinfo::getLLongValue throws an exception in that case, but then
OSRELEASE will not even be attempted. Consequently, kernel and
system map files are not copied, producing the following message:

INFO: Don't copy the kernel and System.map because of missing crash kernel release.
