+Subject: kdump fix ELF header endianess
+References: bnc#888150
+Signed-off-by: Tony Jones <tonyj@suse.de>
+Upstream: pending
+
+The ELF header created among the loading of the kdump kernel should be
+flagged using the current endianess and not always as big endian.
+
+Without this patch the data exposed in /proc/vmcore are not readable when
+running in LE mode.
