Subject: [PATCH 0/2] mm: unexport __get_user_pages_unlocked()
This patch series continues the cleanup of get_user_pages*() functions taking
advantage of the fact we can now pass gup_flags as we please.
It firstly adds an additional 'locked' parameter to get_user_pages_remote() to
allow for its callers to utilise VM_FAULT_RETRY functionality. This is necessary
as the invocation of __get_user_pages_unlocked() in process_vm_rw_single_vec()
makes use of this and no other existing higher level function would allow it to
do so.
Secondly existing callers of __get_user_pages_unlocked() are replaced with the
appropriate higher-level replacement - get_user_pages_unlocked() if the current
task and memory descriptor are referenced, or get_user_pages_remote() if other
task/memory descriptors are referenced (having acquiring mmap_sem.)
