Subject: Support symbol __cpu_online_mask
|
|
References: FATE#323473, bsc#1070291
|
|
Upstream: merged
|
|
Git-commit: d6d5b443c82471818d43cb87c9280a0252e763e7
|
|
|
|
In the upstream kernel, by commit 5aec01b83 cpu_online_mask was replaced
|
|
with macros and new variables __cpu_online_mask was added instead of it.
|
|
Sadump uses cpu_online_mask to check the cpu was online or not,
|
|
therefore it also need __cpu_online_mask symbol for this in the latest
|
|
kernel.
