mm: remove unused macro INIT_PASID

[PATCH] mm: remove unused macro INIT_PASID

Posted by Cheng-Han Wu 7 months, 3 weeks ago

The macro INIT_PASID was originally used by mm_init_pasid. 
However, since commit a6cbd44093ef ("kernel/fork: Initialize mm's PASID"), 
mm_init_pasid has been removed. 
Therefore, INIT_PASID is no longer needed and is removed.
