IB/hfi1: Specify mm when releasing pages This change adds a pointer to the process mm_struct when calling hfi1_release_user_pages(). Previously, the function used the mm_struct of the current process to adjust the number of pinned pages. However, is some cases, namely when unpinning pages due to a MMU notifier call, we want to drop into that code block as it will cause a deadlock (the MMU notifiers take the process' mmap_sem prior to calling the callbacks). By allowing to caller to specify the pointer to the mm_struct, the caller has finer control over that part of hfi1_release_user_pages().
