Subject: [PATCH] utils: Remove arbitrary limit on socket_id/core_id
|
|
|
|
While in most cases the values are going to be much
|
|
smaller than our arbitrary 4096 limit, there is really
|
|
no guarantee that would be the case: in fact, a few
|
|
aarch64 servers have been spotted in the wild with
|
|
core_id as high as 6216.
|
|
|
|
Take advantage of virBitmap's ability to automatically
|
|
alter its size at runtime to accomodate such values.
