Subject: [PATCH 0/2] mm: remove get_user_pages_locked()

by adding an int *locked parameter to get_user_pages() callers to this function
can now utilise VM_FAULT_RETRY functionality.

Taken in conjunction with the patch series adding the same parameter to
get_user_pages_remote() this means all slow-path get_user_pages*() functions
will now have the ability to utilise VM_FAULT_RETRY.

Additionally get_user_pages() and get_user_pages_remote() previously mirrored
one another in functionality differing only in the ability to specify task/mm,
this patch series reinstates this relationship.

This patch series should not introduce any functional changes.

Lorenzo Stoakes (2):
  mm: add locked parameter to get_user_pages()
  mm: remove get_user_pages_locked()
