mm: fix XIP file writes
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: mm: fix XIP file writes
From: Nick Piggin <npiggin@xxxxxxx>
Writing to XIP files at a non-page-aligned offset results in data corruption
because the writes were always sent to the start of the page.
