Subject: [PATCH v8 5/6] vmcore: Enable /proc/vmcore mmap for s390
Date: Tue, 23 Jul 2013 17:47:58 +0200	[thread overview]
Message-ID: <1374594479-64671-6-git-send-email-holzheu@linux.vnet.ibm.com> (raw)
In-Reply-To: <1374594479-64671-1-git-send-email-holzheu@linux.vnet.ibm.com>

The patch "s390/vmcore: Implement remap_oldmem_pfn_range for s390" allows
now to use mmap also on s390.

So enable mmap for s390 again.
