This makes the Linux kernel build as ELFv2 on big endian ppc64. The upstream
|
|
doesn't seem to be interested in this but it's a small patch that is unlikely
|
|
to break/easy to remake and in worst case can always be ditched.
|
|
|
|
Using ELFv2 has some potential performance benefits and is already always used
|
|
on little endian. It requires a relatively modern toolchain, which we already
|
|
have.
|
|
|
|
Ping q66 if it does not apply.
