Subject: [PATCH 1/4] [PATCH v3 1/4] Support symbol __cpu_online_mask
1d9674
1d9674
In the upstream kernel, by commit 5aec01b83 cpu_online_mask was replaced
1d9674
with macros and new variables __cpu_online_mask was added instead of it.
1d9674
Sadump uses cpu_online_mask to check the cpu was online or not,
1d9674
therefore it also need __cpu_online_mask symbol for this in the latest
1d9674
kernel.
