Subject: [PATCH] loader/aarch64: attempt to avoid text relocations in the
|
||
|
|
unknown code
|
||
|
|
|
||
|
|
The commit below added a TEXTREL into the loader library, TEXTRELs
|
||
|
|
and security people don't get on well, so we'd like to avoid that.
|
||
|
|
|
||
|
|
This is my attempt at fixing it, I'm not an aarch64 expert at all,
|
||
|
|
so I'd really appreciate someone who is to take a look.
|
||
|
|
