The patch titled
Subject: i915: use find_lock_page instead of find_lock_entry
has been removed from the -mm tree. Its filename was
i915-use-find_lock_page-instead-of-find_lock_entry.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
Subject: i915: use find_lock_page instead of find_lock_entry
i915 does not want to see value entries. Switch it to use
find_lock_page() instead, and remove the export of find_lock_entry().
Move find_lock_entry() and find_get_entry() to mm/internal.h to discourage
any future use.
