Re: [PATCH 1/2] mm: add locked parameter to get_user_pages()

This patch adds an int *locked parameter to get_user_pages() to allow VM_FAULT_RETRY faulting behaviour similar to get_user_pages_[un]locked().

It additionally clears the way for get_user_pages_locked() to be removed as its sole remaining useful characteristic was to allow for VM_FAULT_RETRY behaviour when faulting in pages.

It should not introduce any functional changes, however it does allow for subsequent changes to get_user_pages() callers to take advantage of VM_FAULT_RETRY.
