Subject: [PATCH] ppc64/kdump: Fix ELF header endianess
|
|
|
de80c6 |
|
|
|
de80c6 |
The ELF header created among the loading of the kdump kernel should be
|
|
|
de80c6 |
flagged using the current endianess and not always as big endian.
|
|
|
de80c6 |
|
|
|
de80c6 |
Without this patch the data exposed in /proc/vmcore are not readable when
|
|
|
de80c6 |
running in LE mode.
