Subject: Try both kexec_load(2) and kexec_file_load(2)
|
||
|
|
References: bsc#951144
|
||
|
|
Upstream: merged
|
||
|
|
Git-commit: ab9c22489ef7627e3f0ad67f46ea19e8d401d044
|
||
|
|
|
||
|
|
The logic in load.sh will use kexec_load first. If kexec_load fails
|
||
|
|
or is blocked by kernel, then it will try kexec_load_file on
|
||
|
|
x86_64.
