The gfp arg is not used in shmem_add_to_page_cache.
Remove this unused arg.

Looks right, but checkpatch.pl has some complaints about the spaces:
please fix those.  Maybe you started off with tabs, and gmail turned
them into spaces.  gmail is an outstandingly excellent mailer (;)
but unhelpful on patches.  See Documentation/email-clients.txt or
Documentation/zh_CN/email-clients.txt.  Maybe "git send-email" will
get around it for you.

Thanks,
Hugh
