Subject: [PATCH] ppc64/kdump: Fix ELF header endianess
|
||
|
|
|
||
|
|
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.
