OK, thanks for that note. According to that history.git [1],
then: drivers/video/pvr2fb.c had get_user_pages_fast() support added to
pvr2fb_write() back in 2004, but only for CONFIG_SH_DMA, as part of

     commit 434502754f2 ("[PATCH] SH Merge")

...and that commit created the minor bug that patch 0001 here
addresses. (+Cc Paul just for the sake of completeness.)
